An eletrophoretic analysis of three species of the subgenus
Dendromyia (Wyeomyia luteoventralis, Wy. ypsipola and Wy.
testei) and three species belonging to different groups in the genus
Wyeomyia (Wy. negrensis, Wy. mystes and Wy.confusa) was
performed. Eight enzyme loci were analyzed. High values of genetic
identity were detected among the species of the subgenus Dendromyia:
Wy. luteoventralis, Wy. ypsipola and Wy. testei (mean value
0.63). On the other hand low values of genetic identity were observed among
Wy. negrensis, Wy. mystes and Wy. confusa (mean value 0.23),
suggesting that they belong, at least, to distinct subgenera within the
Genus Wyeomyia. The UPGMA phenogram revealed the grouping of the
Dendromyia species, while the others clustered at lower identity
levels.
