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

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.

KEY WORDS:
Sawflies; taxonomy; Tenthredinoidea
