The Species of the -Group of (Hymenoptera: Aphelinidae), with Descriptions of Three New Species, DNA Sequence Data and One Newly-Recorded Species from China.

Seventeen species of the -group of (Hymenoptera: Aphelinidae) are reviewed worldwide, including three new species, and five previously described species in China. The -group was defined by a combination of characters: head and body dark with parts of metasoma pale; fore wing with a complete row of setae inside the linea calva, or also only with a few setae in the angle between the linea and marginal vein; legs with mesocoxae, metacoxae and metatibia dark, metafemur pale. In this paper, three new species, Wang & Huang, , Wang & Huang, and Wang & Huang, , are described and illustrated, with notes on one species, Hopper & Woolley, new to China. A revised key to species of the -group is provided. Mitochondrial (COI) partial sequences were obtained successfully for , , and .
