Classificação de Muscidae (Diptera): uma proposta através da análise cladístical

Translated abstract

A cladistic analysis for 27 muscid genera is given, running the PAUP program (SWOFFORD, 1985). The 35 characters used in this study are polarized based on three outgroups of related families. A cladogram showing hypothetical phylogenetic relationships among genera and a discussion of the characters enable to propose a sequencial phylogenetic classification of Muscidae at tribal level. The following seven subfamilies and eight tribes are included: Achanthipterinae; Atherigoninae; Muscinae, with Muscini and Stomoxiini; Azeliinae, with Azeliini and Reinwardtiini; Phaoniinae; Mydaeinae, with Graphomyiini and Mydaeini and Coenosiinae, with Coenosiini and Limnophorini. Helina Robineau-Desvoidy, 1830 has not a defined position in the obtained cladogram to the considered levels. The neotropical species of Phaonia (aut.) must be separated in a new genus. The proposed classification is compared with contemporaneous classifications. The greatest congruence is found with that of SKIDMORE (1985).
