Autapomorphy of Caenopsella/g2.

(1) Gill operculum [see Caenoptera (18)] has no Y-shaped rib, unlike other Caenoptera. As in other respects Caenopsella/g2 is related to Afrocaenis and other Caenis/f4=g2, which have developed Y-shaped rib, we can assume that this rib is secondarily lost in Caenopsella/g2.

Size. Fore wing length 2 mm. 

Distribution. Afrotropical Region.

Nominal species in Caenopsella/g2: 1 species

 meridies Gillies 1977 [Caenopsella]
