Pachynematus perkioemaekii Lindqvist, 1960b: 36–37 .

Diagnosis

Female

5.3–5.5 mm (n = 2). Mostly black body, not bifid claws (with small or large subapical tooth), and lancets should enable separation of females of this species from most of the other Euura . Euura punctifrons , with a small subapical tooth, have a somewhat similar lancet, but this species tends to be smaller (<5 mm) and even darker (pronotum black and femora usually mostly black) than E. perkioemaekii (pronotum posteriorly and femora mostly pale). Very similar can also be dark specimens of E. bipartita , which seem to have somewhat differently shaped serrulae (ventrobasal tip more acute and often more protruding) and at least usually seem to have bifid claws.

Male

The males, which have penis valves most similar to E. bipartita and E. monticola , might not be distinguishable from dark specimens of E. bipartita that have a small subapical tooth on the claw.

Genetics

COI

Based on 2 specimens, maximum within-species distance is 0% and the nearest neighbour, diverging by a minimum of 0.91%, is Euura monticola .

Nuclear

Based on 2 specimens, maximum within-species distance is 0.06% (0.12% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.21%, is Euura bipartita .

Distribution and material examined

Palaearctic. Specimens studied are from Finland.
