Abstract Scorpions and assassin bugs are arthropod predators that may impact in trophic chain, coexisting in similar microhabitats and exhibiting antagonistic interactions. This study reports the first case of predation of the scorpion Physoctonus debilis by the assassin bug Microtomus tibialis in a Brazilian Seasonal Dry Tropical Forest biome. During a nocturnal collection, an adult individual of M. tibialis was observed, with the head and body facing downwards, while holding a female of P. debilis, with the aid of the mouthparts under the vegetation. Reports like these are important to understand the evolutionary dynamics and natural history of predators that cohabit in the same microhabitat.

Resumen Los escorpiones y las chinches asesinas son artrópodos depredadores que pueden impactar en la cadena trófica, coexistiendo en microhábitats similares y exhibiendo interacciones antagónicas. Este estudio reporta el primer caso de depredación del escorpión Physoctonus debilis por la chinche asesina Microtomus tibialis en un bioma de Bosque Tropical Seco Estacional Brasileño. Durante una colecta nocturna, se observó un individuo adulto de M. tibialis con la cabeza y el cuerpo hacia abajo, mientras sujetaba a una hembra de P. debilis con la ayuda del aparato bucal bajo la vegetación. Informes como estos son importantes para comprender la dinámica evolutiva y la historia natural de los depredadores que cohabitan en el mismo microhábitat.

Abstract Almost all reduviids are predators; however, recent observations have shown that certain reduviids, particularly members of tribe Harpactorini (Harpactorinae) may be associated with specific plants as a strategy of predation and complementary nectarivory. These observations on the occurrence of the use of nectar as food source by various species of Reduviidae, mostly Harpactorini, in Argentina (Misiones), are recorded here. Additional records of oviposition and preying by Harpactorini and Bactrodinae species on certain plants are also provided.

Resumen Casi todos los redúvidos son depredadores; sin embargo, varias observaciones han demostrado que algunas especies, en particular los miembros de la tribu Harpactorini (Harpactorinae), pueden estar asociados con plantas específicas como estrategia de predación y complementariamente la nectarivoría. Aquí se registran observaciones recientes del uso del néctar como fuente alimentaria por varias especies de Reduviidae, en su mayoría Harpactorini, en Argentina (Misiones). También se proporcionan registros adicionales de oviposición y depredación por especies de Harpactorini y Bactrodinae en ciertas plantas.

Abstract Aedes aegypti is currently the mosquito with major impact on public health in Brazil and a proven vector of several emerging arboviruses. By consequence, its name is frequently being spoken by lay people of the media and general public, as well as by researchers in this country both in general media and academic events. However, the generic name Aedes, contrary to its etymological origin and worldwide correct pronunciation (“A-e-des”), has been frequently mispronounced as “Edes” on many occasions by media spokespersons and by researchers and lay people in Brazil. However, based on historical and linguistic evidence, it is confirmed here that the correct historical pronunciation (A-e-des) must be maintained and observed in Brazil as it is enunciated all over the World.

Ghilianella beckeri sp. nov. de Emesinae proveniente do Estado de Rondônia, Brasil é descrita. A espécie mais parecida com G. beckeri sp. nov. é G. approximata (McAtee & Malloch 1925). Machos de G . beckeri sp. nov. podem ser separados dos de G. approximata porque estes últimos possuem: (1) o sétimo tergito muito mais curto, ultrapassando levemente o pigóforo e com tegumento liso; (2) processo mediano posterior do pigóforo bifurcado; e (3) parâmeros inermes. Fêmeas de G. approximata podem ser distinguidas das de G . beckeri n. sp. por possuírem: (1) as expansões do quinto tergito abdominal distintamente dentro das margens laterais do disco; (2) o sétimo tergito mais longo do que largo; e (3) oitavo tergito semicircular, com discreta carena mediana.

Ghilianella beckeri n. sp. of Emesinae from Rondônia State, Brazil is described. The most similar species to G. beckeri sp. nov. is G. approximata (McAtee & Malloch 1925). Males of G . beckeri n. sp. can be separated from G. approximata because the latter has: (1) seventh tergite much shorter, slightly surpassing pygophore, and not wrinkled; (2), bifurcated medial posterior process of the pygophore; and (3) parameres without spines. Females of G. approximata can be distinguished from those of G . beckeri n. sp. since they have: (1) the expansions of the fifth abdominal tergum distinctly within lateral margins of disk; (2) the seventh tergite longer than wide; and (3) the eighth tergite semicircular and lightly carinate medially.
