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

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.

“…But the forewing 2+3-A of the new fossil is fused with 1-A at one point close to the center, as in Filacus (see Smith 2003b: fig. 3), while the fusion between 1-A and 2+3-A is much longer in Pachyprotasis (Smith & Gibson 1984;Zhong et al 2010aZhong et al , 2010bZhong et al , 2017Zhong et al , 2018Zhong et al , 2020Zhong et al , 2021Zhong et al , 2022. Among the other genera of the Macrophyini, affinities with the genera Macrophya Dahlbom, 1835, Pseudomacrophya Enslin, 1913, and Deda Gibson, 1980, are also excluded because of their shorter antenna with flattened antennomeres (Gibson 1980a(Gibson , 1980bZombori 1982;Liu et al 2023).…”
