Amauronematus eiteli Saarinen, 1948: 82–83 .

Diagnosis

Females have more or less the same nearly completely or mostly pale orange colouration as E. longiserra and most E. neglecta , but the serrulae of E. eiteli are almost flat (distinctly more protruding in E. longiserra and somewhat more protruding in E. neglecta ). Males are not known for certain: the only candidate (DEI-GISHym84213) seems to be closest to females of E. eiteli based on some analyses of nuclear data, but the large genetic distance might also indicate the presence of additional species in the longiserra group. While penis valves of E. longiserra , E. munda , and E. neglecta are very similar to each other, DEI-GISHym84213 does seem to be different ( Fig. 496 View Figs 492–505 ). The paravalva is basally about as broad as apically in DEI-GISHym84213, while basally narrower than apically in E. longiserra , E. munda , and E. neglecta .

Type material examined

Holotype Amauronematus eiteli

FINLAND – Central Finland • ♀; Pihtipudas ; 63.36° N, 25.55° E; 7 Jun. 1945; A. Saarinen leg.; MZH, http://id.luomus.fi/GL.3375. GoogleMaps

Host plants

Salix pentandra ( Zinovjev & Vikberg 1998; Nyman et al. 2006).

Genetics

COI

Based on 3 specimens, maximum within-species distance is 1.98% and the nearest neighbours, diverging by a minimum of 0%, are Euura longiserra , E. munda , and E. neglecta . After excluding the male specimen (DEI-GISHym84213), which may be a different species, maximum within-species distance is 1.98% and the nearest neighbour, diverging by a minimum of 0.15%, is E. neglecta .

Nuclear

Based on 3 specimens, maximum within-species distance is 0.64% (0.04% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.29%, is Euura neglecta . After excluding the male specimen (DEI-GISHym84213), which may be a different species, maximum within-species distance is 0.02% (0.04% based on haplotypes of individual females) and the nearest neighbour, diverging by a minimum of 0.49%, is E. neglecta .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, and Russia.
