Diagnosis. Antenna moderately long, with verticils rather long, longest verticils subequal in length to their respective segments. Dorsum of thorax suffused with sparse, brownish light grey pruinosity, prescutum without distinct stripes. Wing rather broad, width-length ratio about 1: 3. Male terminalia with single spine at base of gonocoxite, outer gonostylus slender and comparatively short, and paramere broad, with very slight outer distal extension. Wing length 5.8–9.3 mm.

Redescription. Male. Head dark brown, suffused with brownish dark grey pruinosity on frons and vertex. Palpus dark brown, rostrum slightly paler. Antenna dark brown throughout, moderately long, reaching to about base of wing. Flagellum consisting of basal fusion element and subsequent 10 elongate flagellomeres, with verticils sparse, longest ones subequal in length to their respective segments.

Thorax generally dark brown, subshiny, restrictedly suffused with sparse, brownish light grey pruinosity, especially on dorsum, indistinctly paler on anterior paratergite and posterolaterally on scutal lobes. Prescutum without distinct stripes. Wing rather broad, width-length ratio about 1: 3, stigma mostly indistinct. Venation usual for Neolimnophila . Sc 1 ending about opposite fork of Rs. R 2 (cross-vein r) its own length, or more, beyond fork of R 3+4. R 3 subequal in length to R 3+4. Latter vein simply arched. Cross-vein m-cu at from one fourth to one third length of discal cell ( Fig. 10 ). Halter pale throughout. Legs brown, with setae on femora comparatively long and projecting, about twice diameter of femur.

Abdomen dark brown. Male terminalia ( Figs 1–3 ). Tergite 9 interrupted medially. Gonocoxite with single spine at dorsal base, subequal in length to that of N. placida and N. alaskana , about one third length of gonocoxite. Spine with delicate membranous scales in distal half. Quite exceptionally, tiny second spine present in form of bristle, about one sixth length of first spine. Outer gonostylus slender as in N. alaskana , but not as long, about half length of gonocoxite, almost parallel-sided for about two thirds its length, with apical hook, microscopically serrate at outer margin. Paramere rather broad, as in N. alaskana , truncate at apex, distal outer extension barely apparent.

Female resembling male in general appearance, including length and structure of antenna and outline of wing. Female terminalia with cercus long, slender, generally straight, slightly upturned distally, subacute at tip. Hypogynial valve straight, reaching to about middle of cercus.

Distribution. Europe, including European Russia.
