The braconid male genitalia can be used to identify closely-related species. After studying nearly 60 years’ male genitalia, the author summarizs the results of 256 braconid species which are grouped into 114 genera and 28 subfamilies. The structure of male genitalia, its application in species description and the phylogenetic analysis are introduced. Two groups of braconid male genitalia of subfamilies of the family Braconidae are also discussed. This paper further demonstrates that the character distribution of plesiomorphic character-state and apomorphy character-state of male genitalia of subfamilies are “sandwiched” and influenced by the parallelisms.
