Revision of the subgenus Stegana (Steganina) from China, with assessment of species delimitation using DNA barcodes (Diptera, Drosophilidae).

A total of 58 (eight known and 50 new) species of the subgenus Stegana (Steganina) from China were surveyed and (re)described: S. (S.) bacilla Chen & Aotsuka, 2004, S.

Cryptic diversity in the subgenus (Diptera, Drosophilidae, ).

Phylogenetic relationships of the subgenus were reconstructed based on two mitochondrial genes ( and ). The results revealed the paraphyly of and supported high levels of cryptic diversity within this subgenus. By integrating morphological characteristics and molecular evidence, we identified 17 new species as members of : .

The genus Lamb, 1914 (Diptera, Drosophilidae) from southern China.

The genus was established by Lamb in 1914 for a single species, described therein. It contains 13 known species recorded from the Old World (the Oriental, Australasian, Palearctic and Afrotropical regions). In the present paper, five new species discovered from southern China are described as members of : Wang & Gao, , Wang & Gao, , Wang & Gao, , Wang, Li & Gao, and Wang, Li & Gao, The new species were delimitated, based on not only morphological characters but also molecular data.
