ABSTRACT Insects are fundamental to biodiversity conservation in almost all ecosystems, and their population decline, and extinction directly result from environmental impacts. These facts are aggravated by the lack of knowledge of insect biodiversity, the so-called biodiversity deficits, especially the Linnean and Wallacean shortfalls. In freshwater ecosystems, biodiversity loss is higher among aquatic insects, and caddisflies comprise one of the most vulnerable orders. In this way, research focusing on describing new caddisfly species and understanding their distribution ranges will increase knowledge of caddisfly biodiversity. In the past 14 years, the team from the Laboratório de Entomologia Aquática “Prof. Dr. Claudio Gilberto Froehlich” (LEAq, Universidade Federal da Bahia, Brazil) and collaborators have been addressing these issues, resulting in 55 described species of caddisflies. Taxa in other insect orders have also received attention and an additional 16 species have been described (eight mayflies, four stoneflies, four neuropteran spongillaflies, and antlions). Here, eight caddisfly species are described and illustrated (Atopsyche froehlichi sp. nov., Austrotinodes zeferina sp. nov., Cernotina kariri sp. nov., Neoathripsodes froehlichi sp. nov., Notalina claudiofroehlichi sp. nov., Oecetis marcus sp. nov., Phylloicus froehlichi sp. nov., and Polycentropus claudioi sp. nov.), five of them in honor of LEAq’s patron. In addition, new distributional data are presented for 10 known species. A checklist of the caddisfly fauna of Bahia state is also presented, with 138 species, around 75% and 30% of them recorded and described by the LEAq team, respectively. Currently, for caddisflies, Bahia is the fifth most species-rich state in Brazil, and the first in the Brazilian Northeast region. ecosystems decline impacts socalled so called deficits shortfalls insects way 1 years Prof. Prof “Prof Dr Froehlich LEAq, (LEAq Brazil issues 5 mayflies stoneflies spongillaflies antlions. antlions . antlions) Here Atopsyche sp nov nov. , nov.)

Resumen El objetivo principal fue evaluar la población de macroinvertebrados y fitoplancton como bioindicadores de contaminación en la cuenca del río Chicama, Perú. Se ubicó cuatro estaciones; para macroinvertebrados se evaluó mediante el Trent Biotic Index y Chandler Biotic Score, estableciendo la relación entre las variables (abundancia de taxones) con el coeficiente de correlación de Spearman. La evaluación del fitoplancton se realizó mediante el índice saprobio propuesto por Pantle y Buck. Asimismo, se determinó el índice de Shannon Weaver (H´) y el índice de Simpson (D´). La fauna bentónica con 24 géneros, 18 familias y 9 ordenes, predominancia de Baetis sp., Rhagovelia sp. y Atopsyche sp. El fitoplancton estuvo constituido principalmente por diatomeas (Bacillariophyta) y algunas especies pertenecientes a la clase Chlorophyta, con predominancia de Nitzschia linearis, Fragilaria capucina y Gomphonema sp. Finalmente de los índices evaluados, Trent Biotic Index y Chandler Biotic Score, se determinó contaminación leve a moderada de acuerdo al índice de Pantle y Buck.

Abstract The principal objective was to assess phytoplankton and macroinvertebrates as bioindicators of pollution in Chicama river basin, Peru. Was developed four stations and was assess macroinvertebrates by Trent Biotic Index and Chandler Biotic Score, and it was assess the abundance of taxa related to the variables measures, to establish the relationship between the variables with the Spearman correlation coefficient. The assessment of the phytoplankton are carried out through the index proposed by Pantle and Buck; similarly, the index was calculated from Shannon Weaver (H´) and the index of Simpson (D´). It was registered 24 genera of benthuc fauna, 18 families and 9 orders, with a predominance of Baetis sp., Rhagovelia sp. and Atopsyche sp. and to a lesser degree, in comparison with its predecessors, Tricorythodes sp., Clinotanypus sp., and Simulium sp. In regards phytoplankton was composed mainly by diatoms (Bacillariophyta) and some species belonging to the class Chlorophyta, with predominance of Nitzschia linearis, Fragilaria capucina and Gomphonema sp. Finally, the indices evaluated, Trent biotic index and Chandler Biotic Score determined that there is from slight to moderate pollution according to the index of Pantle and Buck.

Los aspectos morfológicos y de comportamiento de insectos permiten agruparlos en gremios, y representar la dependencia de la comunidad lotica hacia recursos alimentarios particulares. Se evaluó los hábitos alimentarios de organismos inmaduros de Ephemeroptera, Plecoptera y Trichoptera (EPT) de la parte media del río Gaira (Sierra Nevada de Santa Marta, Colombia), por medio del análisis del contenido estomacal. Se identificaron 13 géneros de EPT, pero solo a diez de éstos se les revisó el contenido estomacal, para un total de 100 organismos analizados. Se describieron seis ítems alimentarios: restos animales (RA), tejido de plantas vasculares (TPV), Microalgas (MA), hongos (HN), materia orgánica particulada gruesa (MOPG) y materia orgánica particulada fina (MOPF). Baetodes se registró como Recolector-Raspador, ya que su principal ítem alimentario fue MOPF (46.6%) seguido de HN (38.4%). Chimarra, Leptohyphes, Thraulodes y Lachlania, se categorizaron como Recolectores con proporciones promedio de 86.8%, 93.1%, 93.1% y 93.7% de MOPF, respectivamente. En los géneros Phylloicus, Leptonema y Smicridea se observó principalmente TPV y MOPG con 76.3%, 54,6% y 62.4% junto con proporciones de MOPF de 22.3%, 38.8% y 32.9%, respectivamente. Categorizado como Detritívoro, Phylloicus es funcionalmente clasificado como Fragmentador y Leptonema y Smicridea como Recolectores. Los géneros Anacroneuria y Atopsyche fueron clasificados como Depredadores y fueron los únicos taxones en los que se observó RA en altas proporciones (57.9% y 58.2%). Nuestro estudio sugiere que los organismos examinados ingieren una amplia variabilidad de recursos.

Feeding habits of immature individuals of Ephemeroptera, Plecoptera, and Trichoptera from middle reaches of a tropical mountain stream. Morphological and behavioral aspects of insects allow their grouping in trophic guilds and represent their dependence on food resources. We determined the feeding habits of immature organisms of Ephemeroptera, Plecoptera, and Trichoptera (EPT) from the middle reaches of Gaira stream (Sierra Nevada de Santa Marta, Colombia), using gut content analysis. We identified 13 EPT genera, but only ten were analyzed for a total of 100 organisms. We describe six food items: animal parts (AP), vascular plant tissue (VPT), microalgae (M), fungi (F), coarse particulate organic matter (CPOM) and fine particulate organic matter (FPOM). Baetodes was determined to be a collector-scraper, since FPOM represented 46.6% of food content, followed by F (38.4%). Chimarra, Leptohyphes, Lachlania, and Thraulodes were categorized as collectors with average proportions of FPOM 86.8%, 93.1%, 93.1% and 93.7%, respectively. Phylloicus, Smicridea and Leptonema were main consumers of VPT and CPOM with proportions of 76.3%, 54.6%, and 62.4%, respectively; while ratios of FPOM were 22.3%, 38.8%, and 32.9%, respectively. While all are detritivores, Phylloicus is functionally classified as shredders and Smicridea and Leptonema as collectors. Atopsyche and Anacroneuria were the only taxa in which AP were observed in high proportions, 57.9% and 58.2%, respectively, for that reason they were classified as predators. The organisms examined consume a wide variability of resources. Rev. Biol. Trop. 62 (Suppl. 2): 169-178. Epub 2014 April 01.
