Abstract

Geophilomorpha is the most diverse among the five orders of Chilopoda, presenting worldwide, 1250 species in 13 families and 215 genera currently existing. For the Neotropics are known about 316 species, 91 genera and 11 families. The Aphilodontinae subfamily has distribution in southern South American continent and is restricted to South Africa, and today has four genera: Aphilodon with 14 species, these four Neotropical and 10 African, Mecophilus and Mecistauchenus, endemic to Brazil and having one species each and Philacroterium with one valid species to South Africa. In this project are discussed the taxonomy and phylogenetic relationships of the Aphilodontinae genera through morphological study based on material-type deposited in international collections and others not type materials found in major national collections or obtained in field. 12 of the 17 species valid for Aphilodontidae have already been analysed, diagnosed and in some cases redescribed, from 3 international collections. 8 new species are being proposed for Brazil, based on the observation of specimens deposited in Brazilian collections or collected in field. Our preliminary phylogenetic analysis presented in the first report for FAPESP encompassed 12 of the 17 valid species for Aphilodontidae, from 3 international collections and 8 new species are being proposed for Brazil, based on observation of deposited specimens in Brazilian collections or obtained in field. The analysis was rooted by Eucratonix Meinert (Gonibregmatidae) already the external group was composed of 6 representatives of Geophilinae, one for Ribautinae and 3 for Dignatodontinae, all subfamilies Geophilidae. To finalize our project, we hope analyse part of the type material, develop our phylogenetic research and discuss our results with other experts. (AU)
