Revisão e análise cladística do gênero Ascra say, 1832, com considerações sobre a filogenia de Edessinae (Heteroptera, Pentatomidae). 2014. 80 f.

Programa de Pós-Graduação em Zoologia.https://repositorio.ufpa.br/handle/2011/6896Edessinae is one of the largest subfamilies in Pentatomidae, comprising about 300 described species plus 300 undescribed ones divided in only six genera: Edessa, Brachystethus, Peromatus, Olbia, Pantochlora and Doesburgedessa. Most of the species belong to Edessa that carries as well most of the taxonomical problems of the subfamily. This genus is used as a deposit for species not included in the other genera of Edessinae because of the lack of clear limits between the family and the genus Edessa. Solution for such confusion necessarily involves evaluation of the subgenera of Edessa and taxonomical changes in Edessinae. The main goal of this study is to evaluate the taxonomic status of Ascra and its phylogenetic position within Edessinae. We examined 411 specimens from several collections. Descriptions, measurements and photographs of the species, illustrations of metasternal process, male and female genitalia, keys and distributional maps are provided. Cladistic analysis was performed using 28 taxa and 33 morphological characters, eight multistate treated as non additive. The out-group included14 species belonging to all genera of Edessinae and subgenera of Edessa. Edessinae remains monophyletic but Edessa showed up paraphyletic. Ascra is monophyletic supported by two synapomorphies. This genus is now composed by A. bifida, A. cordifera, A. petersii, A. abdita, A. championi, A. privata, A. conspersa, A. morbosa and six new species. Two new groups of species were proposed in Ascra: bifida and privata. Males of A. abdita, A. morbosa and A. cordifera and females of A. championi and A. privata, unknown so far, were described. New nomenclatural arrangements were made. The lectotype of Edessa abdita was designated. Edessa cornuta, Edessa densata, Edessa picata and Edessa florida were considered junior synonyms of A. bifida.porAcesso AbertoTaxonomiaEdessaEspécie (Zoologia)América CentralDissertaçãoCNPQ::CIENCIAS BIOLOGICAS::ECOLOGIA::ECOLOGIA DE ECOSSISTEMASCNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIA::TAXONOMIA DOS GRUPOS RECENTES
