Bithoracochaeta Stein, 1911 (Diptera, Muscidae): revisão das espécies e análise cladística

Bithoracochaeta Stein, 1911 differs from the others Neotropical Coenosiinae by the presence of three very long bristles on the middle of the anterodorsal, anteroventral and posterodorsal surfaces of hind tibia some species have an additional bristle on the posteroventral surface and by the disposition of the dorsocentral bristles 1:2. From the ten known species , eight are redescribed: B. annulata Stein, 1911; B. atricornis Malloch, 1934; B. flavicoxa Malloch, 1934; B. leucoprocta Wiedmann, (1830), B. maricaensis Couri & Motta 1994, B. nigricornis Malloch, 1934; B. plumata Albuquerque, 1955; B. varicornis Coquillettt, ( 1900). The redescriptions of .B. sociabilis Blanchard, 1937 and B. pacifera Giglio-tos, 1893 are not presented because the type of the first one is lost and it was not possible to exame the type of the other. No exemplares of these two species were found in the studied material. A key to identification of the redescribed species is presented. A cladistic analysis was made using the program Hennig86 based on 17 caracters and 3 out-groups. Based on the cladogram, the phylogenetic relationships among the species of this genus are shown.
