C. intriguea Grimaldi & Cumming 1999: 71 .

Diagnosis (revised). Arista dorsal. Base of vein M (proximal to crossveins r-m and bm-cu) complete, but very faint; crossvein r-m either connected to M or with a slight break near connection; vein M2 incomplete at proximal end (either evanescent or abruptly), distal end either incomplete or connected to wing margin; CuA1 complete apically, sometimes faint; anal lobe and alula lost; small spur of vein (CuA2 + CuP) at base of wing; wing very broad, width approximately 0.5x the length. Female terminalia simple, with small pair of cerci broadly connected to abdomen. In Lebanese amber.

Comments. The diagnosis is slightly revised based on a new AMNH female specimen ( Fig. 4 ).
