Gynacantha (A) villosa Grünberg, 1902
Type locality: Langenburg, Tanzania
Male is similar to G. africana by (a) rim of metastigma black, contrasting with colour of thorax; (b) wings may be tinted, but without distinct subcostal rays; (c) mainly 4-5 rows in fork of IR3; (d) largely 2-3 cell-rows between R2 and R3 proximal to Pt; (e) brace veins absent; (f) anal triangle of 3-6 cells; (g) S3 waisted near base; (h) cerci with distinct ventral lump near base (lateral view); (i) cerci widened and sharply cut-off at end, inner border bisinuous, concave roughly 2/3 from base. However, differs by (1) ranging from Kenya and Uganda to NE South Africa and N Botswana; (2) 22-28 Ax in Fw, rather than 28-37; (3) 2, rather than 3 cell-rows between R2 and R3 proximal to Pt, save occasional cell; (4) ventral carinae S5-6 and usually S4 with denticles, rather than all being bare.

Standing and mostly temporary waters shaded by (gallery) forest. Probably often with coarse detritus and a soft (like muddy) bottom. From 0 to 2200 m above sea level, but mostly below 1700.
