Euura platystigma

188 Euura platystigma (Lindqvist, 1949) Figs 203, 435 Pteronidea platystigma Lindqvist, 1949: 74–75. Diagnosis Females are most similar to E. semiopaca, which tends to be darker. In E. platystigma, pale are the head extensively around eyes, antennae ventrally, the abdominal sterna, and downturned parts of terga (mostly black or usually darker in E. semiopaca). Subapical tooth might also usually be smaller than in E. semiopaca. Males of E. platystigma also tend to be paler than those of E. semiopaca, but the differences in penis valves are much clearer (invagination between valvispina and ventroapical margin of paravalva absent or indistinct and shorter valvispina in E. platystigma; in E. semiopaca the invagination between valvispina and ventroapical margin of paravalva is distinct and the valvispina is longer). See also differences discussed under E. dissimilis, which is not known in Fennoscandia. Type material examined Holotype Pteronidea platystigma FINLAND – Inari Lapland • ♀; Utsjoki, Outakoski; 69.61° N, 25.98° E; 25 Jun. 1947; E. Lindqvist leg.; MZH, http://id.luomus.fi/GL.3540. Host plants Astragalus alpinus L. (Vikberg 1978). Genetics COI Based on 11 specimens, maximum within-species distance is 0.61% and the nearest neighbour, diverging by a minimum of 4.26%, is Euura semiopaca. Nuclear Based on 5 specimens, maximum within-species distance is 0.2% (0.23% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 1.03%, is Euura myosotidis. Distribution and material examined Palaearctic. Specimens studied are from Finland, Norway, and Sweden.
