Figs 143, 380

Nematus apicalis Hartig, 1837: 201 . Lectotype designated by Haris (1997). Synonymy by Lindqvist (1955). Primary homonym of Nematus apicalis Stephens, 1835 [ Dineura stilata (Klug, 1816)].

Pachynematus lichtwardti Konow, 1903a: 379 (key). Lectotype designated below.

Pachynematus kubesi Konow, 1905a: 154 . Lectotype designated below. Synonymy by Lacourt (1999).

Diagnosis

Females are most similar to E. moerens . Metatarsomere 1 and metafemur are usually completely or nearly completely black in E. lichtwardti, but usually extensively pale (basal third of metatarsomere 1) in E. moerens . In males, tergum 8 has a distinct apical projection that distinguishes it clearly from E. moerens (absent or indistinct). The penis valves are also distinct from those in E. moerens and the other Euura . In males, sometimes terga 5–8 laterally and laterodorsally pale.

Genetics

COI

Based on 4 specimens, maximum within-species distance is 4.06% and the nearest neighbour, diverging by a minimum of 4.26%, is Euura moerens .

Nuclear

Based on 2 specimens, maximum within-species distance is 0.06% (0.03% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 1.47%, is Euura clitellata cluster 5. Based on 3 specimens of NaK (1654 bp), maximum within-species distance is 0.12% (also 0.12% when considering haplotypes of ZMUO.032405).

Distribution and material examined

Palaearctic. Specimens studied are from Czech Republic, Finland, Germany, Norway, Sweden, and the United Kingdom.
