Resumo
A cladistic analysis of Euprepina 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 the program Hennig86. Character states were polarized following outgroup analysis, and an hypothetical ancestor was included in the analysis in order to root the tree. The options used, "ie*" and "xs w", resulted in four most parsimonious trees with ci = 79, ri = 80 and length 115. The monophiletism of Euprepina was supported by two synapomorphies.

Character states were polarized following outgroup analysis, and an hypothetical ancestor was included in the analysis in order to root the tree. The options used, "ie*" and "xs w", resulted in four most parsimonious trees with ci = 79, ri = 80 and length 115. The monophiletism of Euprepina was supported by two synapomorphies.
