Revisão taxonômica das espécies brasileiras do gênero Argoravinia (Diptera : Sarcophagidae)

Abstract

Sarcophagidae is a family with about 2,600 described species worldwide, with about 800 species in Neotropical region. Argoravinia Townsend, 1917 is a genus of Sarcophagidae (Diptera, Oestroidea) belonging to Sarcophaginae subfamily with Neotropical and Nearctic species, with exception of two species that were introduced in Marshal Island (Australasian/Oceanic region). The genus comprises small to large flies (4 - 9,5 mm), with R1 setulose in basal half and, one or more setae on underside of stem of vein R2+3, ejaculatory apodema large, phallus with very long median stylus, lateral stylus base free. The genus Argoravinia comprised two species until that the genus Raviniopsis Townsend, 1918, with four species, was considered synonym of Argoravinia in the Sarcophagidae catalogue, thus the genus comprises nowadays six species currently described: A. alvarengai Lopes, 1976; A. aurea (Townsend, 1918); A. brasiliana Lopes, 1976; A. candida (Curran, 1928); A. rufiventris (Wiedemann, 1830) and A. timbarensis (Lopes, 1988); however, only fours species were recorded from Brazil. In the present study, the Brazilian Argoravinia species are revised and redescribed: A. alvarengai, A. aurea, A. brasiliana e A. rufiventris. Two new are described from state of Pará: A. catiae sp. nov. and A. paraensis sp. nov. A. alvarengai is recorded for the first time from state of Pará and A. rufiventris is a new record from states of Bahia e Maranhão. An identification key for males and females specimens, illustrations of male and female terminalia, Scanning electron microscopy images, as well as distributional maps are provided.
