Description
259 Euura variator (Ruthe, 1859)
Figs 266–267, 476–477
Nematus variator Ruthe, 1859: 308–310. Lectotype designated below.
Amauronematus godmani Benson, 1955: 104–105. Syn. nov.
Amauronematus galbiventris Lindqvist, 1960a: 130. Syn. nov.
Amauronematus longidens Lindqvist, 1962b: 13. Synonymy by Hellén (1970).
Diagnosis
Females are most similar to E. fasciata and E. obscuripes (toeniata group); see differences discussed under these species. Males might not always be distinguishable from those of the E. obscuripes (toeniata group) and vittata group specimens found in the same (sub)arctic habitats.
Female
5.0– 7.5 mm. Tegula pale or sometimes mostly black, metafemur usually completely or mostly pale, sometimes mostly black, abdomen ventrally extensively pale.
Male
4.0–6.0(6.5) mm. Tegula and metafemur black or partly pale, subgenital plate pale or sometimes black.
Best matches to godmani: ZMUO.044556 (female), ZMUO.059873, ZMUO.058922 (males).

Genetics
COI
Based on 35 specimens, maximum within-species distance is 4.56% and the nearest neighbours, diverging by a minimum of 0%, are Euura opacipleuris, E. fasciata, and E. semilactea.
Nuclear
Based on 30 specimens, maximum within-species distance is 0.98% (0.62% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.37%, is Euura semilactea.
Distribution and material examined
Palaearctic. Specimens studied are from Austria, Finland, Iceland, Norway, Sweden, and Switzerland.
