Euura acuminalis

103 Euura acuminalis (Vikberg, 1982) Fig. 335 Pteronidea acuminata Lindqvist, 1968: 194–195. Secondary homonym of E. acuminata Enslin, 1915 [E. purpureae (Cameron, 1884)]. Nematus acuminalis Vikberg, 1982. Replacement name for P. acuminata. Diagnosis Only the two type specimens were available for study. The holotype male (4.7 mm) is rather pale and has a relatively distinctive penis valve that cannot be associated with any other species of Euura. The studied female paratype is more or less the same colour, but conspecificity with the male is uncertain. Holotype male ventrally pale (also antenna slightly); dorsally black, except last 2–3 terga (6 th slightly); head extensively pale around eyes; hind tibia nearly completely pale; hind tarsi mostly black or brown; pterostigma yellow or brown; claws bifid; projection of tergite 8 longer than broad, rather distinct; antenna long. The female is externally most similar to that of striatipleuris (synonymised here with E. fuscarima), particularly paratypes GL.3547 and GL.3548, but saw may be more similar to that of E. poppii which may also have similar colouration. Placement in the bipartita group is uncertain. Type material examined Holotype Pteronidea acuminata SWEDEN – Torne Lappmark • ♂; Torneträsk; 68.22° N, 19.74° E; 400 m a.s.l.; R.
