Euura punicea Prep.

247 Euura punicea (Christ, 1791) Figs 274, 502 Tenthredo nigrata Retzius, 1783: 73. Described by indication on Degeer (1771: pl. 38 figs 2–4). Type material lost. Type locality: Sweden. Primary homonym of Tenthredo nigrata O.F. Müller, 1776 [= Dolerus (Poodolerus) nigratus (O.F. Müller, 1776)]. Tenthredo punicea Christ, 1791: 440–441. Described by indication on Degeer (1771: pl. 38 figs 2–4). Type material lost. Type locality: Sweden. Tenthredo crocea Fabricius, 1804: 39. Syntypes, sex not stated. Type material probably lost. Type locality: France, Paris. Synonymy by Konow (1905b). Primary homonym of Tenthredo crocea Geoffroy in Fourcroy, 1785 [= Hemichroa crocea (Geoffroy, 1785)]. Nematus melanosternus Serville, 1823: 67. Replacement name for Tenthredo nigrata Retzius. Nematus prototypus Förster, 1854a: 311–313. Lectotype designated below. Synonymy by Konow (1902b). Amauronematus excellens Forsius, 1921: 30–32. Lectotype designated below. Synonymy by Taeger & Blank (1998). Diagnosis Mostly pale body (can be pink in life) and papilliform serrulae usually make identification of the females rather easy, but some specimens of E. vittata group with papilliform serrulae can be similarly pale. The darker cerci of the palest specimens of the E. vittata group (completely or nearly completely pale in E. punicea) and the longer malar space (about as long as the front ocellus in E. punicea) distinguish them. Penis valves are most similar to the closely related E. ranini, but E. punicea seems to be paler (abdomen ventrally completely pale, only subgenital plate pale in E. ranini). Type material examined Lectotype Nematus prototypus, here designated GERMANY – Nordrhein-Westfalen • ♂; Aachen area; 50.77° N, 6.09° E; ZSM, GBIF-GISHym3055. Lectotype Amauronematus excellens, here designated FINLAND – Uusimaa • ♀; Karislojo [Karjalohja]; 60.243° N, 23.723° E; 25–28 Jun. 1910; R. Forsius leg.; emerged 1911 ex larvae on Salix caprea; ZSM, GBIF-GISHym3048. Host plants A wide spectrum of Salix spp. One generation per year. Genetics COI Based on 9 specimens, maximum within-species distance is 3.53% and the nearest neighbours, diverging by a minimum of 0%, are Euura berolinensis, E. ranini. Nuclear Based on 4 specimens, maximum within-species distance is 0.1% (0.28% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.68%, is Euura berolinensis. Distribution and material examined Palaearctic. Specimens studied are from Bulgaria, Estonia, Finland, and Germany.
