Comparative Morphology of the Male Terminalia of Tephritidae and other Cyclorrhapha

摘要

The external morphology and the musculature of the male terminalia of the Tephritidae and other Cyclorrhapha are examined and their homology is discussed. The terms surstylus and bacilliform sclerite are adopted for the ventral projection of the epandrium (apical part of the lateral surstylus of authors) and medial surstylus of the Tephritidae, respectively. The transverse bar, which connects the bases of the bacilliform sclerites (= medial surstyli) and is located at the ventral aspect of the epandrium of the Tephritidae, is a composite structure of the dorsal bridge of the hypandrium and the subepandrial sclerite of other Cyclorrhaphan Diptera.
