230 Euura tota (Saarinen, 1950)

Figs 245, 470

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

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
