Gynacantha (A) sextans McLachlan, 1896
Type locality: Mongo-ma-Lobah, Cameroon
Male is not particularly close to other Gynacantha species, however, belongs to the africana-group by (a) rim of metastigma black, contrasting with colour of thorax; (b) brace veins absent; (c) largely 2-3 cell-rows between R2 and R3 proximal to Pt; (e) inner border of cerci bisinuous, concave roughly 2/3 from base; (d) anal triangle of 3-6 cells. Set apart from the group by (1) wing bases with dark subcostal rays, rather than tinted without subcostal rays; (2) mainly 2-3, rather than 4-5 cell-rows in fork of IR3 in all wings; (3) cerci taper to slender point, rather than being widened and sharply cut-off at end.

Standing and probably often temporary waters shaded by forest. Probably often with coarse detritus and a soft (like muddy) bottom. From 0 to 1300 m above sea level, but mostly below 900, although possibly up to 2600.
