Review of the Pachyprotasis flavipes group (Hymenoptera: Tenthredinidae) from China with descriptions of two new species

Abstract

ABSTRACT The flavipes group of Pachyprotasis Hartig, 1837, with twenty-four species recognized in China, is reviewed. This number includes two newly described species, Pachyprotasis rufodorsata sp. nov., from Sichuan, Hubei, Ningxia, and Shaanxi provinces, and Pachyprotasis nigritarsalia sp. nov., from Hunan province. The mesopleuron and metapleuron of the two new species are reddish-brown, distinguishing them from other similar species of the P. flavipes group. Thirty-four species of this group have been recorded from China, one species (P. variegate Fallén, 1808) was found to be widespread throughout Europe and Siberia, twenty-four were originally described from the China and Burma-Yunnan frontier, eleven from India, and five from Japan. A key to the species of this group from China is provided.
