Abstract

This study contributes taxonomic information on the genus Eutimesius Roewer, 1913. Three new species are described: the sympatric species E. aroa sp. nov. and E. guaichia sp. nov. from Yaracuy state and E. canoabo sp. nov. from Carabobo state in Venezuela. The male of E. ephippiatus (Roewer, 1915) is described for the first time. Remarks are made on the distribution of E. ornatus, and a complimentary description of male genitalia is provided for E. simoni Roewer, 1913. New departmental records are added for E. ephippiatus and E. simoni. An updated distribution map and a key to the identification of the males of the species in the genus are presented.
