Key to genera and species of Maimetshidae

1 Forewing cells 2rm and 3rm both present (2rm sometimes incompletely delimited); flagellomere number variable (unknown for Andyrossia ).................................... 2

– Forewing cells 2rm and 3rm not simultaneously present; 14 flagellomeres ........ 6

2 Second abscissa of RS+M (distal to 1m –cu) shorter than 1m –cu .......................... ................................................ Andyrossia joyceae (Rasnitsyn & Jarzembowski)

– Second abscissa of RS+M (distal to 1m –cu) subequal to or longer than 1m –cu ... .............................................................................................................................. 3

3 Notauli strongly diverging cephalad .................... Afromaimetsha robusta sp. n.

– Notauli more or less parallel ................................................................................ 4

4 Vein RS originating close to pterostigma (prestigma much shorter than 1RS); prestigma incrassate (swollen apically and broader than basal abscissa of R) ........... ........................................................................... Maimetshorapia africana sp. n.

– Vein RS originating well before pterostigma (prestigma about as long as or longer than 1RS); prestigma linear and similar to basal abscissa of R ( Afrapia gen. n.) .............................................................................................................................. 5

5 Pterostigma shorter than (about 0.8×) distance between base of RS and 2r–rs ..... ....................................................................................... Afrapia globularis sp. n.

– Pterostigma as long as or longer than distance between base of RS and 2r–rs ...... ...................................................................................... Afrapia variicornis sp. n.

6 The only rm cell (2rm) anteriorly petiolate; hind wing with free apex of Cu; vertex without medial longitudinal line; eyes bulging ...................................................... ................................. Guyotemaimetsha enigmatica Perrichot, Nel & Néradeau

– The only rm cell (apparently 3rm) anteriorly sessile; hind wing without free apex of Cu; vertex with medial longitudinal line; eyes not bulging, almost following head contour .......................................................... Maimetsha arctica Rasnitsyn
