Key to the Macrophya sibirica group (Hymenoptera: Tenthredinidae) with description of a new species from China

Abstract

The Macrophya sibirica group was proposed by Li et al. (2016). A new species in this group, Macrophya nigrotrochanterata sp. nov. from Liaoning Province, China, is here described and illustrated. A key to all Chinese species and a distribution map of the M. sibirica group in China are provided.

The first sawfly from the Oligocene of Céreste (Southern France) (Hymenoptera: Tenthredinidae)

“…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). In the Sciapterygini genus Zaschizonyx Ashmead, 1898, the fusion between 1-A and 2+3-A is also much longer than in the new fossil (Goulet 1992: figs 339-340).…”
