Abstract：
Recently collected data on the Venezuelan species of the genus Brumptomyia are used to produce an updated review of these sandflies. At present, four species are recognized in Venezuela: B. devenanzii, B. beaupertuyi, B. avellari and B. pintoi. A key for the males is given and the geographical distribution of each of these species is outlined. The previously unknown female of B. devenanzii is described, the male is re-described, and the genetic variability (based on 11 enzymatic loci) of this species and of B. beaupertuyi (a sympatric species in Rancho Grande, the type locality of B. devenanzii) are reported. Fixed allelic differences in one diagnostic locus (adenylate kinase; Ak), between sympatric and allopatric populations, allowed for the unequivocal separation of both sexes of B. beaupertuyi from those of B. devenanzii. Significant inter-specific differences were also detected in the allele frequencies of malate dehydrogenase (Mdh-2) and decarboxylating malate dehydrogenase (Me). For B. devenanzii, mean heterozygosity and mean number of alleles per locus ranged from 2.0%-3.1% and 1.1-1.5, respectively. The corresponding values for B. beaupertuyi were 3.8% and 1.2.
