description: 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. Lectotype ♀ (MNHN), designated by Lacourt (2000), not examined. Type locality: France, Département de l’Isère. Synonymy by (Konow 1904e).
Nematus testaceus Stephens, 1835: 29. 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.
