Morphometrical Characters of the Hypopygiumin the Dolichopodidae (Diptera) and Their Use in the Systematics of the Family

摘要

Morphology of the hypopygium was investigated in 496 species from 128 genera of the family Doli-chopodidae. Based on twenty morphological and morphometrical characteristics, a parsimonic dendrogram of the Dolichopodidae subfamilies was constructed. Variance analysis of the morphometrical data allowed revealing diagnostic characteristics for the subfamilies and genera of Dolichopodidae. Such characteristics as the relative lengths of the epandrium, surstylus, cercus, and apical and basoventral epandrial processes can be used for taxo-nomic diagnostics of the subfamilies and genera.
