KEY TO THE CYRENOBEROTHINAE GENERA 1. Wings: Sc and RA fused apically (forewing of a few specimens of C. penai not fused, but the veins run toward each other and are connected by an apical crossvein) ....................................................................... 2

- Wings: Sc and RA not fused apically ............................................................................................................... 5

2. Forewing: subcostal veinlets forking apically; five or six RP branches. Extant ............................................ 3

- Forewing: subcostal veinlets not forking apically; two or three RP branches. Extinct ................................. 4

3. Forewing with dark marks surrounding the major forks and crossveins. Male gonocoxites 11 with thin dorsal arc connecting the two main pieces. Female with stubby hypocaudae. Southern Africa ..................... ................................................................................................................................................... Manselliberotha

- Forewing hyaline. Male gonocoxites 11 without a thin dorsal arc connecting the two main pieces. Female without hypocaudae. Chile........................................................................................................ Cyrenoberotha

4. Forewing: well-defined pterostigma; Sc + RA without branches; one crossvein between CuP and A1. Early Cretaceous, Lebanon.................................................................................................................. Sibelliberotha

- Forewing: pterostigma not well defined; Sc + RA with long branches forking apically; no crossvein between CuP and A1. Mid Cretaceous, Myanmar..................................................................................... Protoberotha

5. Forewing: most subcostal veinlets forked; one crossvein between MA and MP. Hindwing M fork distal, near the origin of the basal branch of RP. Antennae longer than forewing. Extant, Brazil....................................... .......................................................................................................................................... Speleoberotha gen. nov.

- Forewing: subcostal veinlets not forked; no crossvein between MA and MP. Hindwing M fork basal, near the level of vein 1r-m. Antennae shorter than forewing. Early Eocene, Canada........................... Microberotha
