Amauronematus tenuis Schmidt, 1997: 295–296 .

Diagnosis

Most similar to E. striata and E. septentrionalis . Its usually dark brown or dark grey pterostigma and usually small size (5.5–8.0(8.8) mm) helps to recognize the species. Euura tenuis is genetically very close to E. striata and considering the similarly weak morphological differences between them, conspecificity cannot be excluded. Lamnium 1.8–1.9 times as long as radix (ZMUO.046512, holotype).

Type material examined

Nuclear

Based on 9 specimens, maximum within-species distance is 0.48% (1.19% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0%, is Euura striata (DEIGISHym31412). See notes under Euura striata .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, and Norway.
