Treatment

332 Euura trochanterata (Malaise, 1931)

Pteronidea trochanterata Malaise, 1931a: 149–151 .

Nematus hequensis G.R. Xiao, 1990 . Holotype ♀ (CFRB?), not examined. Type locality: China, Shanxi Province, Hequ County. Syn. nov.

Diagnosis

The black pterostigma and mesepisternum, yellow costa, mostly black abdomen, reddish head and reddish thorax dorsally, and mostly black femora make the females rather easily recognizable. Penis valves ( Xiao 1990) might not be clearly distinguishable from, e.g., the melanocephalus and miliaris groups. Larvae ( Wang et al. 2015) are most similar to those of E. miliaris or E. salicis . Phylogenetically (based only on COI,>1000 bp) appears to be closest to E. salicis and the E. melanocephalus group.

Type material examined

Holotype Pteronidea trochanterata

RUSSIA – Primorsky Kray • ♀; Vladivostok, Sedanka ; 43.21° N, 131.96° E; 12 Aug. 1930; R. Malaise leg.; NHRS, NHRS-HEVA000006438 . GoogleMaps

Notes

The holotype is 8.2 mm long, not 9 mm as stated in the original description. Based on the details given in Wang et al. (2015), Nematus hequensis is not different from Pteronidea trochanterata Malaise.

Host plants

Salix spp. and Populus spp. ( Wang et al. 2015).

Genetics

COI

Based on 2 specimens (NC_072336, identified as Nematus trochanteratus and NC_072337 identified as N. hequensis ), maximum within-species distance is 0.91% and the nearest neighbour, diverging by a minimum of 3.96%, is Euura vicina .

Nuclear No data.

Distribution and material examined

East Palaearctic. Specimens studied are from China (only genetics), Russia.
