Genus Cenocimbex Nel, 2004

Figs. 2, 3E–F.

Type species C. menatensis Nel, 2004 .

Emended diagnosis. Separated from all other Cenocimbicinae by R before base of pterostigma with dark triangular sclerite reaching 1-Rs+M near 1m-cu [vs. sclerotization not apparent, either absent or pale, small]; by wing broad, estimated length/width 2.5 [all others ca. 2.8 or more]; by cell 3rm short (2r-m to 3r-m length ≤ 3r-m [vs. distinctly longer]); from Leptostigma n. gen. also by pterostigma broad, maximum height distinctly more than height of C to R basal to pterostigma [ Leptostigma n. gen.: similar in height to C to R basal to pterostigma]. Hind wing with r-m, m-cu and cu-a only moderately distant from each other (for about length of m-cu, so cu-a at about midlength cell mcu) [in other genera usually well before mid-length].

Remarks. Sclerotisation on R near the pterostigma, even though of much lesser size, is clearly seen in an extant cimbicine, see Vilhelmsen et al. 2018, Fig. 2B).

Locality and age. Menat Formation; Puy-de-Dôme, France; Selandian.
