Figs 151 View Figs 150–153 , 385 View Figs 380–393

Nematus dorsatus Cameron, 1875: 129–130 . Syntypes ♀♀ (BMNH?), not examined. Type locality: United Kingdom, Scotland, Inverness-shire, Rannoch, and Bishopton.

Diagnosis

Nearly completely pale, and thus resembling most specimens of E. flavescens , at least some E. latibasis , and E. seriepunctata . Serrulae of the lancet of E. dorsata are more protruding than in E. flavescens and E. seriepunctata . Euura latibasis might have a shorter lamnium compared to radix (lamnium 1.8–1.9 times as long as radix in E. latibasis , about 2.0–2.4 times as long in E. dorsata ). Euura fuscarima of the E. bipartita group is also similar externally and has a similar lancet. The middle and apical sutures of the lancet of E. fuscarima are perhaps straighter than in E. dorsata .

Host plants

Betula pubescens including ssp. czerepanovii (N.I.Orlova) Hämet-Ahti.

Genetics

COI

Based on 2 specimens, maximum within-species distance is 0.31% and the nearest neighbour, diverging by a minimum of 1.67%, is Euura latibasis .

Nuclear

Based on 2 specimens, maximum within-species distance is 0% (0.03% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 2.4%, is Euura reticulata .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, and Sweden.
