The allozyme variation between 2 sympatric populations of Lecithochirium furcolabiatum and L. rufoviride was examined with the aim to investigate if the 2, morphologically similar, helminths are reproductively distinct. Three enzyme loci, Gpd, Pgm-1, and Idh were found to be diagnostic for the 2 species. These results support the conclusion that the worms are different biological species. Only the Gpi and Gdh loci showed no differences. Marked genetic subdivision was detected at the Idh locus in the L. rufoviride population. Given that the genotypic distribution at Pgm-1 showed no significant deviations from Hardy–Weinberg expectations, it does not appear that the absence of heterozygotes for Idh was caused by the reproductive structure of the population. Although there are several other possible reasons for the deficiency of heterozygotes in natural populations, the existence of a new noninterbreeding group within the population studied constitutes a plausible explanation.
