Nematus monticola Thomson, 1871: 147 . Lectotype designated below.

Nematus pschornwalcheri Muche, 1972: 34–37 . Holotype ♀ (OLML), not examined. Type locality: Switzerland, Jura, Franches Montagnes, Etang de la Gruère. Synonymy by Lacourt (1999).

Pachynematus vaginosus Konow, 1903a: 381 (key). Syntypes ♀ ♂: specimens lost, only slide of penis valves (PR.231AZ) found in DEI. Type locality: Russia, Irkutsk. Syn. nov.

Diagnosis

The most similar species is E. bipartita : see discussion under that species. Synonymy of Pachynematus vaginosus Konow is based on the penis valve (preparation PR.231AZ in SDEI) of a presumably syntype specimen, which resembles most closely E. monticola .

Extensively pale, abdomen with distinct black line dorsally or at least terga 1–2 extensively black, pterostigma pale, claws bifid, valvula 3 in dorsal view elongate, gradually tapering.

ZMUO.063341 is slightly darker (fore and middle femora at base and abdomen dorsally more extensively black, valvula 3 mostly black) than the syntype DEI-GISHym88923. Male ZMUO.061039 has small subapical tooth.

Genetics

COI

Based on 6 specimens, maximum within-species distance is 3.5% and the nearest neighbour, diverging by a minimum of 0%, is Euura bipartita .

Nuclear

Based on 5 specimens, maximum within-species distance is 0.92% (0.34% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.35%, is Euura bipartita .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, Sweden, and the United Kingdom.
