Euura ranini

248 Euura ranini (Lindqvist, 1960) Figs 275–276, 503 Amauronematus ranini Lindqvist, 1960b: 33–34. Diagnosis Females are most similar to E. lethe (E. tunicata group), that have a similar lancet. Mesepisternum and mesonotum may be paler (always with reddish markings?) and the basal annuli seem to be narrower than in E. lethe (mesepisternum and mesonotum always black?). Although serrulae of two Finnish specimens (including the holotype) of ranini and the sequenced specimen from the Russian Far East (DEI-GISHym80671) are somewhat different, externally no significant differences can be observed. The penis valve drawn by Lindqvist (1971a) matches well with the sequenced specimen from the Russian Far East and the nuclear sequences are nearly identical to a sequenced Finnish larva. The penis valves are most similar to E. punicea, but sterna 2–6 are (always?) black (pale in E. punicea). Type material examined Holotype Amauronematus ranini FINLAND – Uusimaa • ♀; Helsinge [Vantaa]; 60.30° N, 24.90° E; 17 May 1959; O. Ranin leg.; MZH, http://id.luomus.fi/GL.2757. Host plants Populus tremula. One generation per year. Genetics COI Based on 3 specimens, maximum within-species distance is 0.76% and the nearest neighbours, diverging by a minimum of 0%, are Euura berolinensis and E. punicea. Nuclear Based on 3 specimens, maximum within-species distance is 0.18% (0.04% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.72%, is Euura punicea. Distribution and material examined Palaearctic. Specimens studied are from Finland, and Russia.
