Three new species of the subgenus Parapenthecia from the Oriental Region (Diptera: Drosophilidae: Apenthecia)

摘要

Three new species of the subgenus Parapenthecia of the genus Apenthecia are reported from the Oriental Region: A. (P.) heterochaeta Chen and Toda, sp. nov. from Indonesia, and A. (P.) hispida Chen and Toda, sp. nov. and A. (P.) litongi Cao and Chen, sp. nov. from south China. Interestingly, the last species lacks a very peculiar character, the swollen or scale-like orbital setae, which are commonly seen in all other species of the genus Apenthecia. A key to all species of the subgenus Parapenthecia is provided.
