Nematus (Amauronematus) longicauda Hellén, 1948: 113–114 . Lectotype designated below.

Diagnosis

Females are most similar in colouration to E. munda , but with distinctly more pronounced serrulae. Serrulae are similar to E. longiserra , although apparently narrower, but E. longicauda is dorsally also darker (mostly black, E. longiserra nearly completely or mostly pale). Males possess a valvispina and a long and thin apical extension of pseudoceps, while a valvispina is missing in the other three species of Euura that have a long apical extension of pseudoceps ( E. abnormi s, E. cornuta , and E. amentorum ).

Genetics

COI

Based on 7 specimens, maximum within-species distance is 1.67% and the nearest neighbour, diverging by a minimum of 0.76%, is Euura abnormis .

Nuclear

Based on 3 specimens, maximum within-species distance is 0.32% (0.22% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.94%, is Euura abnormis .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, Norway, and Sweden.
