Autapomorphy of Oligoneuriella/fg2.

(1) On each penis lobe the proximal sclerotized process directed medially-ventrally [see Oligoneuriella/g1 (1)] is saddle-shaped, curved distally and sclerotized in such a manner that its median side is membranous, and a boundary between the sclerotized and the membranous areas is dentate; thus it looks as if this process has two rows of denticles a medial-dorsal and medial-ventral ones (Kluge 2004: Fig.46:B, 47:A).

Size. Fore wing length 916 mm.

Distribution. Palaearctic; all species in Western Palaearctic, only one of them pallida [O.] all over Palaearctic.
