Fig. 236

Nematus nivalis Muche, 1973a: 223–224 . Secondary homonym of Pontania nivalis Vikberg, 1970b [= Euura nivalis (Vikberg, 1970) ].

Euura elbrus Sundukov, 2017a: 13 . Replacement name for Nematus nivalis Muche, 1973 .

Diagnosis

The saw is most similar to E. propinquator , although colouration of the abdomen (hind margins of dorsal parts of terga not as extensively pale as in E. propinquator ) and the likely host plant might indicate a different species. Lamnium 1.4 (?) times as long as radix.

Type material examined

Holotype Nematus nivalis

RUSSIA – Elbrus Region • ♀; Itkol; 43.25° N, 42.54° E; 2800 m a.s.l.; 9 Jul. 1971; ZMHB, dbcac7 / GBIF-GISHym2827 .

Host plants

Unknown, but probably not Salix repens L. (the host of E. propinquator ), because the type specimens were collected above the tree line.

Genetics

COI

No data.

Nuclear No data.

Distribution and material examined

Palaearctic. Specimens studied are from Russia.
