Análise cladística de Euprepina Hull (Diptera, Bombyliidae, Bombyliinae)

Abstract

Cladistic analysis of Ellprepina Hull, (Diptera, Bombyliidae, Bombyliinae). A cladistic analysis of Ellprepina Hull, 1971 (Diptera, Bombyliidae, Bombyliinae), a Neotropical genus that includes ten species, was made. The cladogram was obtained from eight studied species, based on a data matrix with 21 characters, using lhe program Hennig86. Character states were polarized following outgroup analysis, and an hypothetical ancestor was included in the analysis in order to roOI the tree. The options used, "ie*" and "xs w", resulted in four most parsimonious trees with ci = 79, ri = 80 and length 115. The monophilelism of Euprep ina was suppolted by two synapomorph ies.

Biogeographic analysis of Crocidiinae (Diptera, Bombyliidae): finding congruence among morphological, molecular, fossil and paleogeographical data

“…A number of phylogenetic studies have been published at several levels (e.g., Yeates 1989Yeates , 1992Yeates , 1994Evenhuis 1990;Zaitzev 1992;Greathead 1995Greathead , 1996Greathead , 1998Greathead , 1999Lamas & Couri 1999Lambkin et al 2003), however, none of them treated the studied group on a temporal scale. One of the key concerns for systematists and biologists involved in the Tree of Life project is the calibration of phylogenies against time, with the source data coming from molecular and paleontological studies (Benton & Ayala 2003).…”
