Euura latibasis

156 Euura latibasis (Lindqvist, 1949) Figs 152, 387 Pteronidea latibasis Lindqvist, 1949: 77–79. Diagnosis Females are from nearly completely pale to mostly black dorsally, and pale ventrally. Externally and based on the lancet, most similar to E. dorsata and E. fuscarima (E. bipartita group). Lamnium is 1.8–1.9 times as long as radix in E. latibasis (n = 1), but about 2.0–2.4 times as long in E. dorsata (n = 2) and 2.3–2.8 times as long in E. fuscarima (n = 2), but the difference might not hold for E. latibasis and E. dorsata. The middle and apical sutures of the lancet of E. fuscarima might also be more straight than in E. latibasis. Euura seriepunctata and E. serela sp. nov. have also quite a similar lancet, but the serrulae seem to be less protruding and the lamnium is 2.3–2.4 (n = 1) times as long as the radix in E. seriepunctata (the proportions could be similar in E. serela based on one basally damaged lancet). Type material examined Holotype Pteronidea latibasis FINLAND – Varsinais-Suomi • ♀; Pargas (Parainen); 60.305° N, 22.301° E; leg. E. Reuter leg,; MZH, http://id.luomus.fi/GL.3505. Notes Best morphological fit: ZMUO.035649. Host plants Unknown. Genetics COI Based on 3 specimens, maximum within-species distance is 0.15% and the nearest neighbour, diverging by a minimum of 1.67%, is Euura dorsata. Nuclear Based on 2 specimens, maximum within-species distance is 0% (0.02% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.33%, is Euura lienterica. Distribution and material examined Palaearctic. Specimens studied are from Finland.
