No. of bitstreams: 1 273714.pdf: 9709500 bytes, checksum: f178a08d9ff3f96dc0663592d8abeed8 (MD5) Previous issue date: 1996-04-23 / CAPES / Bithoracochaeta Stein, 1911 distingue-se dos demais Coenosiinae neotrópicos principalmente pela presença, na tíbia posterior, de pelo menos três cerdas medianas longas e finas nas faces ântero-dorsal, ântero-ventral e póstero-dorsal; algumas espécies apresentam uma cerda mediana adicional na face póstero-ventral e pela disposição das cerdas dorsocentrais 1:2. Das dez espécies citadas na literatura, oito são redescritas: 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). As redescrições de B. sociabilis Blanchard, 1937 e B. pacifera Giglio-Tos, 1893, não foram apresentadas, pois os sintipos da primeira se encontra perdido e não foi possível examinar o holótipo da segunda. Nenhum exemplar destas espécies foi identificado no material examinado. Uma çhave de identificação para espécies redescritas é apresentada. A análise cladística, utilizando o programa Hennig86 foi feita baseada em 17 caracteres e 3 grupos-externos. Com base no cladograma constnúdo foram mostradas as relações filogenéticas entre as espécies no gênero. / 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.
