ABSTRACT
Hershkovitzia Guimarães & D'Andretta, 1956 belongs to Nycteribiidae, composed of hematophagous species exclusively ectoparasites of bats. The new species was collected from the bat Thyroptera devivoi Gregorin, Gonçalves, Lim & Engstrom, 2006 (Chiroptera: Thyropteridae) from Barreirinhas in Maranhão State, Brazil. Herein, we proposed schematic drawings of the abdomen, legs and head. We also proposed an identification key to species of Hershkovitzia.

We investigated whether biting midges in peridomestic environments are affected by environmental management practices and the presence of domestic animals. We used CDC light traps to collect midges in 112 residences across 24 locations along tourism routes of Maranhão, Brazil. The collection areas were characterized as follows: i) peridomestic area with domestic animals and without management (dirty); ii) peridomestic with domestic animals and management (clean); iii) peridomestic without animals and with management (clean); iv) peridomestic without animals and without management (dirty). The first two treatments had higher biting midge species richness and abundance, respectively. Generalized linear models indicated a positive correlation between the presence of domestic animals and midge abundance, with an approximate four-fold increase in Culicoides (Diptera: Ceratopogonidae) abundance in peridomestic areas with animals. The same model showed that domestic animals have no influence on richness. Environmental management does not appear to influence species richness or abundance of biting midges.

This study reports the first records of the parasitism rates of the association among ectoparasitic flies of the family Streblidae found in phyllostomid bats in the state of Maranhão. Specimens were collected in patches of secondary forest and borders of mangrove in the village of Quebra Pote, located in the south portion of the island of São Luís. A total of 201 flies of 15 species and eight genera [Aspidoptera falcata Wenzel, A. phyllostomatis (Perty), Mastoptera minuta Costa Lima, Megistopoda aranea (Coquillett), M. proxima (Séguy), Speiseria ambigua Kessel, Stizostrebla longirotris Jobling, Strebla guajiro (García & Casal), S. hertigi Wenzel, Trichobioides perspicillatus (Pessôa & Galvão), Trichobius costalimai Guimarães, T. dugesii Townsend, T. dugesioides phyllostomus Guerrero, T. joblingi Wenzel and T. longipes (Rudow)] were collected from 50 individuals of nine species of phyllostomid bats [Artibeus lituratus (Olfers), A. obscurus Schinz, Carollia perspicillata L., Glossophaga soricina Pallas, Lophostoma carrikeri J A Allen, Micronycteris minuta Gervais, Phyllostomus discolor Wagner, P.hastatus Pallas and Sturnira lilium E Geoffroy)]. Mastoptera minuta, T. costalimai, T. longipes, A. falcata and S. longirostris, were the most frequently found ectoparasites, present in at least 50% of the infected bats. Two species of bats, C. perspicillata e P. discolor, showed the highest richness of ectoparasites, with four species of flies each, and an infection rate of 46% and 100%, respectively.

Este estudo constitui o primeiro registro de taxas de parasitismo da associação entre moscas ectoparasitas da família Streblidae e morcegos da família Phyllostomidae para o Maranhão. As coletas foram realizadas em área de bosque peridomiciliar e de borda de mangue do povoado do Quebra Pote, no sul da Ilha de São Luís. Foram coletadas 201 moscas pertencentes a 15 espécies de oito gêneros [Aspidoptera falcata Wenzel, A. phyllostomatis (Perty), Mastoptera minuta (Costa Lima), Megistopoda aranea (Coquillett), M.proxima (Séguy), Speiseria ambigua Kessel, Stizostrebla longirotris Jobling, Strebla guajiro (García & Casal), S. hertigi Wenzel, Trichobioides perspicillatus (Pessôa & Galvão), Trichobius costalimai Guimarães, T. dugesii Townsend, T. dugesioides phyllostomus Guerrero, T. joblingi Wenzel e T. longipes (Rudow)] infestando 50 filostomídeos de nove espécies [Artibeus lituratus (Olfers), A. obscurus Schinz, Carollia perspicillata (L.), Glossophaga soricina Pallas, Lophostoma carrikeri J A Allen, Micronycteris minuta Gervais, Phyllostomus discolor Wagner, P. hastatus Pallas e Sturnira lilium (E Geoffroy)]. As espécies mais frequentes foram: M. minuta (28,9 por cento), T. joblingi (24,4 por cento), M. aranea (12,9 por cento) e A. phyllostomatis (5,5 por cento). As espécies de ectoparasitos mais prevalentes foram M. minuta, T. costalimai, T. longipes, A. falcata e S. longirostris, por encontrar-se infestando, pelo menos, 50 por cento dos indivíduos de uma espécie hospedeira. Carollia perspicillata e P. discolor apresentaram a maior riqueza de ectoparasitas, sendo cada uma, infestada por quatro espécies de moscas, apresentando taxa de infestação de 46 por cento e 100 por cento, respectivamente.
