Euura miliaris PR.

176 Euura miliaris (Panzer, 1797) Figs 195, 423 Tenthredo miliaris Panzer, 1797: 45:13. Holotype ♀, probably lost or destroyed. Type locality: Germany. Nematus dorsalis Serville, 1823: 73.

Syntypes ♀♀ (BMNH?), not examined. Type localities: United Kingdom, England, Kent, Darenth Wood, and Devonshire. Nematus fulvus Hartig, 1837: 194. Synonymy by Kriechbaumer (1884). Nematus purus Förster, 1854a: 278–279. Lectotype designated below. Synonymy by Dalla Torre (1894). Nematus fulvus var. basalis Costa, 1859: 18–19. Syntypes ♀♀ (MZFN?), not examined. Type locality: Italy, Naples area. Synonymy by Dalla Torre (1894). Nematus trimaculatus Snellen van Vollenhoven, 1862: 69–71, pl. 4. Lectotype ♀ (RMNH), designated by Thomas (1987), not examined. Type locality: Netherlands Zuid-Holland, Leiden. Synonymy with N. fulvus by Kaltenbach (1869). Primary homonym of Nematus trimaculatus Serville, 1823 [= Euura ribesii (Scopoli, 1763)]. Nematus solitarius Zaddach, 1883 in Brischke 1883: 179. Holotype ♀ (ZMHB), not examined. Type locality: Denmark, Copenhagen? Synonymy by Konow (1904e). Pteronus magus Marlatt, 1896a: 44–46 (key), 67. Holotype ♀ (ANSP), not examined. Type locality: Canada. Syn. nov. Based on Smith (2004), a very good match is DEI-GISHym31136. Pteronidea miliaris var. nigronotata Enslin, 1916a: 453. Syntypes ♀♀ (not located in ZSM). Type locality: not stated. Synonymy by Lacourt (1999). Diagnosis Pale specimens are very similar to E. fagi: see differences mentioned under that species. Abdomen of live females can be green. In northern Fennoscandia, females can be dorsally extensively black, like Pteronus magus from North America (see Smith 2004). Larvae from Canada belonging to BIN cluster BOLD:AAN8145 fit perfectly with E. miliaris, but not with E. fagi or E. nigricornis. Type material examined Holotype Nematus fulvus GERMANY – Niedersachsen • ♀; Harz; 51.8° N, 10.3° E; W. Saxesen leg.; ZSM, GBIF-GISHym3286. Lectotype Nematus purus, here designated GERMANY – Niedersachsen • ♀; Hannover; ZSM, GBIF-GISHym3396. Paralectotype Nematus purus GERMANY • ♀; ZSM, GBIF-GISHym3397. Notes Pteronus magus. Based on Smith (2004), a very good morphological match is DEI-GISHym31136. Host plants A wide spectrum of Salix spp. (Taeger et al. 1998). Genetics COI Based on 6 specimens, maximum within-species distance is 2.45% and the nearest neighbour, diverging by a minimum of 3.20%, is Euura fagi. Nuclear Based on 3 specimens, maximum within-species distance is 0.07% (0.13% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 1.18%, is Euura fagi. Distribution and material examined Holarctic. Specimens studied are from Austria, Canada, China (only genetics), Denmark, Finland, France, Germany, and Sweden.
