Abstract Introduction: The use of arthropods in ecological studies in the tropical dry forest (TDF) of Colombia focused mainly on spiders, butterflies, ants, and dung beetles; therefore, it is necessary to understand the seasonal dynamics of the other groups such as Geadephaga in this ecosystem. Objective: To evaluate the spatio-temporal variations and the effect of environmental conditions on the diversity of the Geadephaga communities in two TDF fragments in the Colombian Caribbean. Methods: This study was conducted during four sampling events between February and June 2018, each lasting four days, and four nights. Four sampling stations were selected in each locality (Reserva Campesina La Montaña = RCM and Reserva La Flecha = RLF), separated 350 m one from another, with square plots of 50 × 50 m. A light trap was installed in the center of each square, while pitfall traps were installed in the four vertices, and manual capture, beating sheets and leaf litter sieve were carried out. Results: A total of 348 Carabidae and 114 of Cicindelidae were captured. In both fragments, the richness and abundance presented the lowest values in dry season, while the highest values were observed during the rainy season. Tetracha affinis (Dejean, 1825) was the most abundant species in RCM during rainy season. Conclusions: The richness variation and abundance of Geadephaga corresponds to a seasonal pattern at both locations. A high dissimilarity between the communities of Geadephaga from the two fragments was found, despite having similar environmental conditions.

Resumen Introducción: El uso de artrópodos en estudios ecológicos en el bosque seco tropical (Bs-T) de Colombia se centra mayormente en arañas, mariposas, hormigas y escarabajos coprófagos; por lo tanto, es necesario comprender como es la dinámica estacional de otros grupos como Geadephaga en este ecosistema. Objetivo: Evaluar la variación espacio-temporal y el efecto de las condiciones ambientales sobre la diversidad de las comunidades de Geadephaga en dos fragmentos de Bs-T en el Caribe colombiano. Métodos: El estudio se llevó a cabo en cuatro eventos de muestreo entre febrero y junio de 2018; cada uno con una duración de cuatro días y cuatro noches. En cada localidad (Reserva Campesina La Montaña = RCM y Reserva La Flecha = RLF), se marcaron cuatro estaciones distanciadas 350 m, con parcelas de 50×50 m. En el centro de cada parcela se instaló una trampa de luz, mientras que en los cuatro vértices se instalaron trampas de caída, y se realizó captura manual, cernido de hojarasca y perturbación de follaje. Resultados: Se capturó un total de 348 ejemplares de Carabidae y 114 de Cicindelidae. La riqueza y la abundancia presentaron los valores más bajos durante el período seco, mientras que los mayores valores se observaron durante el período de lluvias, en ambos fragmentos. Tetracha affinis (Dejean, 1825) fue la especie más abundante en la RCM durante el período lluvioso. Conclusiones: La variación de la riqueza y abundancia de Geadephaga responde a un patrón estacional en ambos fragmentos. Se encontró una amplia disimilitud entre las comunidades de Geadephaga de ambos fragmentos, pese a tener condiciones ambientales parecidas.

ABSTRACT Crop damage-based control threshold of 12.5% has been used to reduce the excessive use of insecticides while controlling Spodoptera litura and Helicoverpa armigera in hot peppers (Capsicum annuum L.) cultivation systems. However, it is necessary to develop an easy, practical, inexpensive control threshold to increase farmer eagerness in reducing pesticide use. The study aimed to evaluate a light trap captured based-control threshold for both hot pepper pests. The activity was conducted at Lembang (ca. 1250 m a.s.l.), West Java, Indonesia, from September 2022 to April 2023. Six treatments and four replicates were arranged in a randomized block design. The treatments included the use of four light trap captured based-control thresholds, i.e., ≥ 30, ≥ 25, ≥ 20, ≥ and 15 moth trap-1 wk-1; crop damage based-control threshold of 12.5%; and once per week insecticide application as a control treatment. The study found that the implementation of pests’ control threshold of ≥ 25 moth trap-1 wk-1 could reduce 75% insecticide use compared to the plant damage-based control threshold. The use of this approach could maintain high crop production and generate a return rate of 1.26. The findings will be beneficial for farmers in reducing insecticide use.

Abstract Background: Utricularia jamesoniana, a small epiphytic plant found in wet tropical forests, stands out for its carnivorous habit, intricate trap system, and small but beautiful and complex flowers. This species remains relatively understudied despite its wide geographical distribution and curious adaptations. Questions: Our aim is to elucidate the composition of bacterial and fungal communities inhabiting both the bladders and leaves of Utricularia jamesoniana, facilitating the comprehension of the physiology and ecological dynamics of this carnivorous species. Methods: In this study, we employed 16S rRNA and ITS sequencing to compare the prokaryotic and fungal communities within leaves and traps of U. jamesoniana. Results: The analysis of amplicon sequence variants (ASVs) unveiled notable differences in community composition depending on the plant tissue and type of microorganism. Prokaryotic communities predominantly comprised Proteobacteria and Actinobacteriota, featuring genera such as Acidocella, Bradyrhizobium, Ferritrophicum, and Ferrovum. Fungal communities were dominated by Ascomycota and Basidiomycota, encompassing representatives of Dothideomycetes, Sordariomycetes, Eurotiomycetes, and Agaricomycetes, as well as ASVs related to Mycosphaerellaceae, Colletotrichum, Aspergillus, and Thanatephorus. We determined that the prokaryotic diversity was higher in the bladders with respect to the leaves. Fungal communities, in turn, were more diverse in leaves than in bladders. Conclusions: This study sheds light on the microbial communities associated with this carnivorous epiphyte and provides valuable insights into the intricate relationships between the plant and its microbial inhabitants across different tissues.

Abstract A Collapsible Light Trap (CLT) for collecting insects, particularly aquatic insects, is described here. CLT is a modified Pennsylvania Light Trap with the advantage of being collapsible and lightweight to be carried in a small backpack and very easy to set up in the field. CLT is equipped with LED light strip wrapped around a PVC tube and can be connected to a regular 12 V / 7 Ah battery, running for more than 48 uninterrupted hours. Complete CLT weighs 0.8-1.0 kg, depending on the metal used, and the battery weighs around 2 kg, being easily transportable to more remote collecting areas. Over the years, CLTs have been used for collecting and describing the diversity of aquatic insects from Brazil, particularly caddisflies. Depending on the locality, only one trap for one night can collect over a thousand insect specimens and more than 200 individuals of caddisflies.

ABSTRACT Here, single-trap, multiple-release-recapture field experiments were used for the first time to estimate the trap sampling area and absolute population density from trap catches for the coffee berry borer (CBB) Hypothenemus hampei (Ferrari). Fluorescent-dusted CBBs were released at several distances at all four cardinal points from an ethanol-methanol-baited multifunnel trap. Only 2.6 % of released beetles were recaptured, and recaptures decreased significantly with increasing release distances. The recapture analyses revealed that CBB moves randomly in the field and disperses at a maximum of 22.2 m. Despite the short plume of the trap (1.3 m), the calculated trap sampling area was 0.17 ha, with an overall catch probability of 0.01. Therefore, capturing 100 CBBs trap –1 ha –1 at the early filling stage of coffee beans reflects a 20.2 million borers ha –1 population at harvest. This results in a projected bean loss of 60.3 kg ha –1 . The findings shed light on improvements in using semiochemical traps and interpretations of catch data to enhance the CBB integrated management. Future studies on the performance of attractants and trap designs in different coffee farmscapes are encouraged to adopt the present methodology.

Resumen La Reserva Natural Urutaú está ubicada en el suroeste de la provincia de Misiones, Argentina, entre los departamentos de Candelaria y Capital. Dicha provincia tiene un registro general de 194 especies de mosquitos incluyendo vectores de patógenos y parásitos que causan enfermedades al humano y animales. El objetivo de este trabajo es conocer la comunidad de mosquitos particularmente en el área de la reserva, comparar el desempeño de las técnicas de muestreo de adultos utilizada y considerar la importancia sanitaria de dicha comunidad. Se colectaron larvas, pupas y adultos. Comparando el número de especies e individuos adultos capturados con diferentes metodologías, red/aspirador fue la más eficaz para capturar diversidad de especies, mientras que la trampa de luz CDC lo fue para la variable número de individuos. Confirmamos 30 especies de mosquitos pertenecientes a nueve géneros, estando 12 de ellas implicadas en la transmisión de patógenos o parásitos. Entre ellas, Sabethes (Sabethes) albiprivus Theobald, la única especie de mosquito de la cual se ha aislado el Virus de la fiebre amarilla en Argentina. Adicionalmente, registramos Culex (Culex) lahillei Bachmann & Casal por primera vez en la provincia de Misiones, y tanto Aedes (Protomacleaya) terrens (Walker) como Culex (Melanoconion) ribeirensisForattini & Sallum son nuevas citas para el Departamento Capital, Misiones.

Abstract Urutaú Natural Reserve is a protected area in the southwest of Misiones province, Argentina. Regarding the mosquito fauna, 194 species have been recorded for Misiones province so far. It is known that many of them are vectors of pathogens and parasites that cause human and animal diseases. The objective of this work is to understand the mosquito community in order to consider their importance in pathogens and parasites transmission and compare different capturing techniques for mosquito diversity. Larvae, pupae and adults were collected. Comparing the number of species and individuals captured as adult with different methodologies, Net /insect hand aspirator was the most effective methodology capturing diversity of species while CDC light trap captured significantly higher number of individuals. We confirmed the presence of 30 mosquito species belonging to nine genera, of which 12 are suspected of being involved in pathogen transmission. Among them, Sabethes (Sabethes) albiprivus Theobald, the only mosquito from which the Yellow fever virus has been isolated in Argentina. Additionally, we recorded Culex (Culex) lahillei Bachmann & Casal for the first time in Misiones province, and Aedes (Protomacleaya) terrens (Walker) and Culex (Melanoconion) ribeirensis Forattini & Sallum are new citations for Capital Department, Misiones.

SUMMARY The box tree moth poses a threat to the Anatolian boxwood (Buxus sempervirens) which has significant economic and ecological value in Türkiye. This study aimed to determine the economic feasibility of pest control with solar-powered light-pheromone (SPLP) traps against the box tree moth in the Ağva Forest District of Şile Forest Enterprise, which is the only region in Türkiye with a management plan for boxwood shoot utilization. For the economic feasibility analysis, approaches including net present value, benefit-cost ratio, and the comparison of discounted finite cost of control with the capital value of infinite revenues were used. Considering the revenues of the Şile Forest Enterprise from the sale of the boxwood shoots in a finite period, it was found that pest control with the SPLP traps is not economical, producing a benefit-cost ratio of 0.371 with a net present value of -229,647.10 TL. In addition to the revenue of the enterprise, after taking into account regional income losses, water production value, and the benefits of other non-market ecosystem services provided by boxwood areas, the benefit-cost ratio increased to 2.688, and pest control became economically feasible. It was determined that the capital value of the infinite annual revenues from boxwood shoots was greater than the present value of the pest control costs against the box tree moth in a period.

RESUMEN La polilla del boj, representa una amenaza para el boj de Anatolia (Buxus sempervirens), que tiene un valor económico y ecológico significativo en Turquía. Este estudio tuvo como objetivo determinar la viabilidad económica del control de plagas con trampas de feromonas de luz alimentadas con energía solar (SPLP) contra la polilla del boj en el distrito forestal de Agva de Sile Forest Enterprise, que es la única región de Turquía con un plan de gestión para la utilización de los brotes de boj. En el análisis de viabilidad económica, se utilizaron enfoques que incluían el valor actual neto, la relación costo-beneficio y la comparación del costo finito de control descontado con el valor de capital de los ingresos infinitos. Considerando los ingresos de Sile Forest Enterprise por la venta de los brotes de boj en un período finito, se encontró que el control de plagas con las trampas SPLP no es económico, produciendo una relación costo-beneficio de 0,371 con un valor presente neto de -229.647,10 TL. Además de los ingresos de la empresa, considerando las pérdidas de ingresos regionales, el valor de la producción de agua y los beneficios de otros servicios ecosistémicos no comerciales proporcionados por las áreas de boj, la relación costo-beneficio aumentó a 2,688 y el control de plagas se volvió económicamente viable. Se determinó que el valor de capital de los ingresos anuales infinitos de la utilización de los brotes de boj era mayor que el valor actual de los costos de control de plagas contra la polilla del boj en un período.

Abstract Zinc oxide (ZnO) is prepared by Chemical Bath Deposition (green chemistry) technique at ~ 80.0 ± 2oC temperature. This manuscript continues with previous research examining the Photoluminiecence spectra situated at UV-Vis-egion. In this investigation, three different molar concentrations of the progenitor reagent containing the Zn2+ cation are chosen in order to find the optimal conditions for crystal growth and determine the influence of this parameter on crystal growth. The average grain size and lattice strain using Scherrer’s equation and Williamson-Hall ( W - H ) method are discussed. The normalized absorbance situated at UV-region, electronic transitions located at ~ 239 nm (~ 5.18eV) and ~ 283 nm (~ 4.38eV) associated with quantum confinement are appreciated. We consider that the inorganic nanomaterial has native defects and the strain is caused by point defects (vacancies and interstices). According to emission bands situated at Vis-region by means of Photoluminescence spectroscopic technique, green (GE) and yellow emission (YE) bands are discussed, which are associated with native defects. The Photoluminescence dependence with the trap density and the surface recombination velocity in the light of the Maxwell-Boltzmann theoretical model (MBM) results associated with the electronic transitions related to the native defects situated at Vis-region are investigated. The trap density c m - 3 of nanocrystals located at range ~ 8.9 — 9.9 × 1023. An approximate theoretical-experimental the kinetic model is shown, considering that the coordination complex ion is a key parameter in the crystal growth of Z n O nanocrystals. The optimized geometry of Z n N H 3 4 2 + molecule was obtained with the DFT method using the functional of H-GGA B3LYP.

ABSTRACT Chickpea is a commercially exploited crop on a relatively new scale in Brazil, that is why, little information on the main pests is available. Mostly caterpillars showing Heliothinae morphological characteristics have emerged in production areas. In order to point out the species of these insects in chickpea fields produced in the Federal District and the surrounding areas, this study aimed to determine the morphological and molecular identification of these invertebrates in order to assist producers in pest management in a more sustainable way. Caterpillars were hand-collected directly from the plants in six sites and the moth collection was collected using light traps in four sites, monthly, in 2017 and 2018. The morphological identification was made through the adult insect genitalia and the subsequent molecular identification was performed using the cytochrome oxidase I enzyme with the quantitative PCR technique, which resulted in the development of an efficient and low-cost DNA extraction protocol to be used in samples under unfavorable storage conditions. Morphological and molecular studies showed the presence of Helicoverpa armigera, Helicoverpa zea, Chloridea virescens and Chloridea subflexa, with a predominance of Chloridea virescens in chickpea plants. Chloridea subflexa was verified for the first time feeding on chickpeas in Brazil.

RESUMO O grão-de-bico é uma cultura com exploração comercial em escala relativamente nova no país e, por isso, há poucas informações disponíveis sobre as principais pragas, majoritariamente lagartas, com características morfológicas de Heliothinae, que têm surgido nas áreas de produção. Com o intuito de apontar as espécies desses insetos no grão-de-bico produzido no Distrito Federal e região produtora em seu entorno, este trabalho foi realizado para a identificação morfológica e molecular desses invertebrados para auxiliar os produtores no manejo de pragas de forma mais sustentável. Foram realizadas coletas manuais de lagartas diretamente nas plantas em seis locais e a coleta de mariposas com o uso de armadilhas luminosas em quatro locais, mensalmente, durante os anos de 2017 e 2018. A identificação morfológica foi feita através da genitália dos insetos adultos e a posterior identificação molecular foi realizada através da enzima citocromo oxidase I com a técnica de PCR quantitativo, o que resultou no desenvolvimento de um protocolo de extração de DNA eficiente e de baixo custo para o uso em amostras sob condições desfavoráveis de armazenamento. Os estudos morfológico e molecular resultaram na constatação da presença de Helicoverpa armigera, Helicoverpa zea, Chloridea virescens e Chloridea subflexa, com predominância de Chloridea virescens nas plantas de grão-de-bico.

Abstract Areas planted with Eucalyptus urophylla S.T. Blake variety platyphylla F. Muell. (Myrtaceae) expand annually in most regions of Brazil. Many lepidopteran species defoliate this plant, but with damage varying per species. The objective of this study was to identify the pest status of lepidopteran defoliators based in the faunistic analysis of these insects and of their natural enemies on E. urophylla variety platyphylla plantations in a representative producing region of Brazil. Adult moths of lepidopterans and of their natural enemies were captured using a light trap, installed every two weeks, from September 2016 to August 2018. A total of 183, 10, three and 139 lepidopteran species was captured and classified as primary, secondary, without defined importance to eucalypt plants and non-identified with 1,419, seven, 465 and 876 individuals, respectively. Two primary pest species were constants, two accessories and six accidentals and all secondary ones were accidentals. Six primary pest species were common and dominant and four non-dominants. Faunistic indices indicated the main lepidopteran species that should be monitored in pest management programs. Seven hymenopteran species (65 individuals), three dipterans (49 individuals) and two hemipterans (four individuals) were the natural enemies collected using light traps. The monitoring of lepidopteran pests with light traps can contribute to the management and to reduce damage and control costs for these species, besides identifying natural enemies for biological control programs in Eucalyptus plantations.

Resumo Áreas plantadas com Eucalyptus urophylla S.T. Blake variedade platyphylla F. Muell. (Myrtaceae) se expandem anualmente na maioria das regiões do Brasil. Muitas espécies de lepidópteros desfolham esta planta, mas com danos que variam de acordo com a espécie. O objetivo deste estudo foi identificar o status de praga de lepidópteros desfolhadores com base na análise faunística desses insetos e de seus inimigos naturais em plantios de E. urophylla variedade platyphylla em uma região produtora representativa do Brasil. As mariposas e seus inimigos naturais foram capturadas com armadilha luminosa, instalada quinzenalmente, de setembro de 2016 a agosto de 2018. Um total de 183, 10, três e 139 espécies de lepidópteros foram capturadas e classificadas como primária, secundária, sem importância definida para eucaliptocultura e não identificadas com 1419, sete, 465 e 876 indivíduos, respectivamente. Duas espécies de pragas primárias foram constantes, duas acessórias e seis acidentais e todas as secundárias foram acidentais. Seis espécies de pragas primárias foram comuns e dominantes e quatro não dominantes. Os índices faunísticos indicaram as principais espécies de lepidópteras que devem ser monitoradas em programas de manejo de pragas. Sete espécies de himenópteros (65 indivíduos), três dípteros (49 indivíduos) e dois hemípteros (quatro indivíduos) foram os inimigos naturais coletados com armadilha luminosa. O monitoramento de lepidópteros-praga com armadilha luminosa pode contribuir para o manejo e redução de danos e custos de controle para essas espécies, além de identificar inimigos naturais para programas de controle biológico em cultivos de eucalipto.

The woodwasp, Sirex noctilio, is a global pest of pines. Although it is known to be attracted to light and possess sexually dimorphic body colouration, the visual ecology of S. noctilio is poorly understood. Photoreceptor sensitivity of the compound eyes in S. noctilio is not sexually dimorphic. These previous results suggest that colour tracking of one sex by the other might not be an important input for mate searching. This study aimed to expand our knowledge of the visual system of S. noctilio by means of i) morphological description of the compound eyes and ocelli; and ii) semi-field behavioural tests of the colour preference of newly emerged wasps. Eye and ocellus morphological features were investigated in 21 males and 21 females. Measurement of male and female median ocellus diameter, compound eye surface area, number of ommatidia and facet diameter varied from 0.22 to 0.40 mm, 0.589 to 2.277 mm², 1820 to 4207 and 1.88 × 10-2 to 2.82 × 10-2 mm, respectively. In addition, all traits significantly correlated with body size. Male and female wasps emerged from infested host material in a flight cage with five traps, each reflecting a different colour. Analysis of trap captures did not identify any colour preference, but an effect of trap location was observed with traps in the north-eastern position capturing more woodwasps, suggesting that other factors, e.g., global landmarks or other non-colour visual cues might guide initial flight behaviour of S. noctilio.

Culicoides truuskae Labuschagne and Meiswinkel sp. n. is described and illustrated in both sexes from material collected in South Africa and Namibia. It is restricted to the xeric western margin of the subcontinent, occurring in Fynbos, Nama-Karoo and Succulent Karoo ecoregions in South Africa and Desert and Savanna ecoregions in Namibia experiencing < 600 mm of rainfall annually. Culicoides truuskae sp. n. is part of the Afrotropical 'plain-wing' Culicoides in which the wing lacks a distinguishing pattern of light and dark spots; the diagnostic dark smudge that traverses wing cell r3 may result in C. truuskae sp. n. being misidentified as the sympatric but phyletically unrelated Culicoides herero (Enderlein) - (of the Similis group, subgenus Oecacta Poey). Additionally, this study is the first description of the male of C. herero. C. truuskae sp. n. and Culicoides coarctatus Clastrier and Wirth share similar characters in the male genitalia, although the two species are separable on wing pattern and female flagellum sensilla coeloconica (SCo) distribution. The breeding habitat and adult female blood-feeding preferences of C. truuskae sp. n. are not known. A maximum likelihood phylogenetic tree, using mitochondrial cytochrome c oxidase I (COI) sequence data, is provided to further clarify the relationship between C. truuskae sp. n., C. coarctatus and C. herero. Extensive light trap data, collected over 30 years, are used to map the distribution ranges of C. truuskae sp. n., C. coarctatus and C. herero in Southern Africa. CONTRIBUTION: The description of this new species and the description of the male of C. herero increases our understanding of the diversity and distribution of Culicoides species in southern Africa.

Scope: A general list of species is provided for the department of Santander, as well as two new records for the area of influence of the Sogamoso Hydroelectric Power Plant. Results: A total of 705 Lutzomyia were collected, distributed in 21 species, and some that are vectors of cutaneous leishmaniasis stood out for their abundance and importance including: Lutzomyia gomezi, L. panamensis, and L. ovallesi, and L. longipalpis prevailed in visceral leishmaniasis. Two new reports are presented for Santander: L. sanguinaria and L. strictivilla. Conclusion: The significant presence of vectors involved in the transmission of leishmaniasis represents a risk for this disease to occur in the populations in the study area.

Abstract: In this study, the composition, distribution, and abundance of cumaceans collected in Isla Mujeres and Isla Contoy National Parks, Quintana Roo, Mexico, were evaluated. The specimens were collected with a scoop net (0.30 m wide by 0.48 m long and 330 µm mesh opening). The trawls were carried out on submerged vegetation in 10 m long transects parallel to the coastline. Additionally, at a station in Isla Mujeres, a white light trap with an intensity of 30 lm was used. The values of physicochemical parameters were measured in situ, which were within established by the official Mexican standard for uncontaminated waters; temperature (27.26 ± 0.64 °C); salinity (35.65 ± 0.21); dissolved oxygen (8.01 ± 0.88 mg L-1); total dissolved solids (22.82 ± 0.22 ppm); and pH (8.07 ± 0.15). Regarding the families Bodotriidae and Nannastacidae, a total of 7,590 specimens belonging to 5 genera and 18 species were identified. Cumella sp. “A” was the most abundant species with 5,364 specimens followed by Vaunthompsonia floridana with 1,391 specimens. Vaunthompsonia minor was recorded in 9 of the 11 sampling stations. The geographic distribution ranges of Cyclaspis mexicansis, Cumella achimae, C. bacescui, C. andri, C. caribbeana, C. croixensis, C. medeeae, and C. somersi were extended. The highest diversity and equitability occurred in Isla Mujeres (3.05 and 0.88 bits ind-1, respectively). The genus Vaunthompsonia was dominant in Isla Mujeres, while the genus Cumella was dominant in Isla Contoy.

Resumen: En este estudio se evaluó la composición, distribución y abundancia de cumáceos colectados en los Parques Nacionales Isla Mujeres e Isla Contoy, Quintana Roo, México. Los especímenes fueron recolectados con una red de cuchara (0,30 m de ancho por 0,48 m de largo y 330 µm de apertura de malla). Los arrastres se realizaron sobre vegetación sumergida en transectos de 10 m de largo paralelos a la línea de costa. Adicionalmente, en una estación de Isla Mujeres se utilizó una trampa de luz blanca con una intensidad de 30 lm. Se midieron los parámetros fisicoquímicos in situ, los cuales estuvieron dentro de los valores establecidos por la norma oficial mexicana para aguas no contaminadas; temperatura (27,26 ± 0,64 °C); salinidad (35,65 ± 0,21); oxígeno disuelto (8,01 ± 0,88 mg L-1); sólidos disueltos (22,82 ± 0,22 ppm); y pH (8,07 ± 0,15). En cuanto a las familias Bodotriidae y Nannastacidae, se identificaron un total de 7.590 ejemplares pertenecientes a 5 géneros y 18 especies. Cumella sp. “A” fue la especie más abundante con 5.364 ejemplares seguida de Vaunthompsonia floridana con 1.391 ejemplares. Se registró Vaunthompsonia minor en 9 de las 11 estaciones de muestreo. Se amplió el rango geográfico de distribución de Cyclaspis mexicansis, Cumella achimae, C. bacescui, C. andri, C. caribbeana, C. croixensis, C. medeeae y C. somersi. La mayor diversidad y equidad se presentó en Isla Mujeres (3,05 y 0,88 bits ind-1, respetivamente). El género Vaunthompsonia fue dominante en Isla Mujeres, mientras que el género Cumella fue dominante en Isla Contoy.

Resumen El género Eudevenopus incluye 4 especies válidas, son habitantes de aguas relativamente poco profundas en ambos lados de América. En este artículo se describe e ilustra una quinta especie, recolectada con una trampa de luz en Sisal, península de Yucatán. Eudevenopus winfieldi sp. nov. puede distinguirse de otras especies del género por el dactilo del pereópodo 7, que es tan largo como el própodo, el artejo 1 de la antena 1 del flagelo del macho con 2-4 estetes, un peine de 6 setas pectinadas distales en el margen posterodistal del carpo del gnatópodo 2, el pedúnculo del urópodo 3 tiene una sola seta intermedia robusta en el margen externo. También se proporcionan una clave de identificación y una tabla comparativa para contrastar la especie nueva con E. honduranus, que es la especie reconocida más cercana.

Abstract The genus Eudevenopus includes 4 valid species, inhabitants of relatively shallow waters in both sides of America. A fifth species, collected with a light trap in Sisal, Yucatán Peninsula is described and illustrated in this paper. Eudevenopus winfieldi n. sp. can be distinguished from other species in the genus by the pereopod 7 dactylus, which is as long as propodus, article 1 of flagellum antenna 1 of the male with 2-4 aesthetascs, a comb of 6 distal pectinate setae on the posterodistal margin of the carpus of gnathopod 2, and the uropod 3 peduncle, which has a simple robust intermediate seta on the external margin. An identification key and a comparative table are also provided to contrast the new species from E. honduranus, which is the closest recognised species.
