Abstract

Electrophoretic characterizations of sibling species in the Simulium venustum–verecundum complexes are presented based on nine enzymatic loci. Simulium verecundum s.l. is easily separable from S. venustum s.l. by unique complements of electromorphs for lactate dehydrogenase. Quantitative and minor qualitative differences also exist between most pairs of sibling species within S. venustum and S. verecundum. Not all pairs are separable using the nine enzymatic loci scored in this study. This close genetic affinity of species pairs that are not separable by electrophoretic methods parallels their chromosomal and ecological affinity.

Résumé

La caractérisation électrophorétique d'espèces jumelles des complexes Simulium venustum–verecundum a été effectuée en utilisant 9 loci enzymatiques. Simulium verecundum s.l. est facilement separable de S. venustum s.l. par des profiles uniques d'électromorphes pour la dehydrogenase lactique. Des différences quantitatives et qualitatives mineures existent aussi entre la plupart des paires d'espèces jumelles chez S. venustum et S. verecundum. Il est impossible de séparer toutes les paires sur la base des neuf loci enzymatiques examinés dans cette étude. Cette affinité génétique étroite pour les paires d'espèces inséparables par les méthodes électrophorétiques est similaire à leur affinité chromosomique et écologique.
