Systematic study of the subgenus Aphantorhaphopsis of the genus Siphona in East Asia and the Oriental Region (Diptera: Tachinidae)

Abstract

Nineteen species of the subgenus Aphantorhaphopsis Townsend, 1926 of the genus Siphona Meigen, 1803 from East Asia and the Oriental Region are revised. Of these, 14 species are classified into three species groups based mainly on the male postabdomen: the S. perispoliata group, the S. selecta group and the S. siphonoides group. Autapomorphies of each species group are defi ned and illustrated. Ten species are described as new: Siphona (Aphantorhaphopsis) apicisetosa sp. nov., S. (A.) coactilis sp. nov., S. (A.) curta sp. nov., S. (A.) curvata sp. nov., S. (A.) expleta sp. nov., S. (A.) hongkongensis sp. nov., S. (A.) kanmiyai sp. nov., S. (A.) matsumotoi sp. nov., S. (A.) nepalensis sp. nov., and S. (A.) seminigra sp. nov. A key is provided for the 19 East Asian and Oriental species.
