Amauronematus leucopyga Lindqvist, 1949: 69–70 . Holotype ♀, paratypes ♀ ♂. Type specimens not found in MZH. Type locality: Finland.

Pteronidea bipicta Lindqvist, 1959c: 56 . Synonymy by Lindqvist (1967b).

Amauronematus crassiserra Lindqvist, 1960a: 129 . Syn. nov.

Diagnosis

Euura leucopyga is most similar to E. connecta : see differences mentioned under that species. Head shape can be similar to “ Amauronematus ”. Valvula 3 can sometimes be rather broad and square-shaped in dorsal view and with a small invagination posteriorly ( crassiserra ) similar to some Euura polaris specimens, but lancets of these species are distinguishable (see under Euura polaris ).

Female

Head extensively or slightly pale around eyes; labrum and clypeus pale; supraclypeal area black or pale (usually); thorax black; pronotum and tegula pale; pterostigma pale; metafemur and metatibia pale; hind tarsus pale or brown; abdomen dorsally nearly completely black, ventrally mostly black to mostly pale.

Male

Head extensively pale around eyes to nearly completely black; labrum pale; clypeus pale or black; supraclypeal area black (usually?); thorax black; pronotum and tegula pale; pterostigma pale; metafemur pale or basally black; metatibia pale or laterally black; hind tarsus pale or brown; abdomen dorsally nearly completely black, ventrally mostly black to mostly pale; sternum 9 pale.

Type material examined

Holotype Pteronidea bipicta

FINLAND – Central Finland • ♀; Pihtipudas ; 63.36° N, 25.55° E; 8–9 Jun. 1946; E. Lindqvist leg.; MZH, http://id.luomus.fi/GL.3569.

Notes

Best morphological match: DEI-GISHym21390.

Holotype Amauronematus crassiserra

FINLAND – Lapin Lääni • ♀; Kilpisjärvi; 69.04° N, 20.81° E; 20 Apr. 1954 [ex larva rearing emergence date]; E. Lindqvist leg.; MZH, http://id.luomus.fi/GL.2525.

Notes

COI sequence (275 bp) of the holotype is identical to E. connecta , most specimens of E. leucopyga , and some specimens of E. parviserrata and E. sordidiapex .

Host plants

Salix spp.

Genetics

COI

Based on 25 specimens, maximum within-species distance is 3.95% and the nearest neighbours, diverging by a minimum of 0%, are Euura parviserrata and Euura sordidiapex .

Nuclear

Based on 21 specimens, maximum within-species distance is 0.83% (0.78% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.25%, is Euura connecta .

Distribution and material examined

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