description: 252 Euura toeniata (Serville, 1823)
Figs 271, 479, 480
Nematus toeniatus Serville, 1823: 67–68. Syntypes ♀♀, probably lost (Lacourt 2000). Type locality: France, Paris area.
Tenthredo humeralis Zetterstedt, 1838: 351. Lectotype designated below. Synonymy by Lindqvist (1941b). Secondary homonym of Nematus humeralis Serville, 1823 [Euura humeralis (Serville, 1823)].
Amauronematus aemulus Konow, 1895: 183. Lectotype designated below. Synonymy by Konow (1905b).
Amauronematus alpicola Konow, 1895: 183–184. Lectotype designated below. Synonymy by Lindqvist (1959c) is here re-instated.
Amauronematus zetterstedti Malaise, 1921a: 127. Replacement name for Tenthredo humeralis Zetterstedt, 1838.
Diagnosis
Most similar to E. obscuripes, which usually has a paler pterostigma (usually black in E. toeniata). Nearly complete black specimens may not be reliably distinguishable similarly coloured E. obscuripes. Paler specimens of E. toeniata have more whitish or greyish markings rather than brown or reddish as in E. obscuripes. Euura toeniata is genetically similarly diverse as E. obscuripes but morphologically less variable (e.g., never with reddish markings on mesepisternum).
Type material examined
Lectotype Tenthredo humeralis, here designated
SWEDEN • ♀; locality on label illegible; MZLU, MZLU2017263.
Notes

Paralectotype Tenthredo humeralis
UNKNOW COUNTRY • ♀; MZLU, MZLU2017262.
Lectotype Amauronematus aemulus, here designated
GERMANY – Bayern • ♂; Herrieden; 49.23° N, 10.49° E; 23 Apr. 1890; Schultheiss leg.; SDEI, GBIFGISHym4101.
Notes
Penis valve most similar to ZMUO.033962.
Lectotype Amauronematus alpicola, here designated
SWITZERLAND – Uri • ♀; Andermatt; 46.64° N, 8.61° E; SDEI, GBIF-GISHym4087.
Host plants
A wide variety of Salix spp. (Lacourt 1999; Macek et al. 2020), including S. caprea, S. myrsinifolia, S. myrtilloides L. and S. repens rosmarinifolia.
Genetics
COI
Based on 24 specimens, maximum within-species distance is 2.58% and the nearest neighbour, diverging by a minimum of 0%, is Euura obscuripes. When including also secondary intraindividual COI variants, maximum within-species distance is 8.21%. Two divergent secondary variants (0.76% different from each other but 7.45–7.60% different to the primary variant) were detected in ZMUO.064027 from Utsjoki, Finland, which are closest to E. obscuripes (DEI-GISHym31073) from California, USA (with distance of 2.74–2.89%).
Nuclear
Based on 19 specimens, maximum within-species distance is 0.99% (0.68% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.07%, is Euura obscuripes. When excluding the E. obscuripes specimen DEI-GISHym19806 with only 1529 bp of NaK and POL2 available, E. obscuripes is minimum of 0.15% different.
Distribution and material examined
Palaearctic. Specimens studied are from Austria, Bulgaria, Estonia, Finland, Germany, Norway, Russia, Sweden, and Switzerland.
