Amauronematus histrio ab. totus Lindqvist, 1941a: 67 . Infrasubspecific and therefore unavailable name.

Amauronematus totus Saarinen, 1950b: 58 . Holotype ♀ not found in MZAT or MZH, possibly lost. Type locality: Finland, Suomussalmi.

Diagnosis

Mostly black body (usually?) and lancet (ventrally concave in middle part and slightly convex apically, short setae, lamnium 1.6–1.8 times as long as radix [http://id.luomus.fi/GP.110201, DEI-GISHym84215, ZMUO.078382]) distinguishes the species from the others in the histrio group. Both males and females can have a reddish band on the abdomen like E. histrio , but females of E. tota have black tegula and mesepisternum unlike females of E. histrio (pale tegula and usually pale mesepisternum). Males with a red band might not be distinguishable from those of E. histrio .

The blunt valvula 3 in lateral view and pointed and smooth scutellum are shared with and typical for histrio ( Lindqvist 1941a: 67) . There is an empty place with a label “ totus ” and no pin holes in the MZAT collection (Anssi Teräs pers. com.).

Host plants

Salix lapponum .

Genetics

COI

Based on 5 specimens, maximum within-species distance is 1.38% and the nearest neighbours, diverging by a minimum of 0%, are Euura histrio , E. stenogaster , E. septentrionalis , E. amicula , E. nuorbinjargi , E. striata , and E. tenuis .

Nuclear

Based on 4 specimens, maximum within-species distance is 0.76% (0.51% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.5%, is Euura histrio .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, and Sweden.
