Abstract.
Eleven enzyme systems were used to compare 2
cryptic species previously treated as Psychodopygus carrerai. Two enzyme systems were each completely diagnostic. Three other
loci gave evidence of reproductive isolation: the combined ge
notypic frequencies departed from Hardy-Weinberg equilibri
um and the allele frequencies were different. The genetic dis
tance between the 2 species is relatively small, suggesting that
they are closely related.
