Trithemis hartwigi Pinhey, 1970
Type locality: Fernando Po (= Bioko), Guinea
Male belongs to one of several Trithemis species with (a) Hw base yellow, orange or amber, colour usually surpasses Cux; (b) hamule with short, strongly curved hook; (c) Abd largely pale with some black markings, appears orange, red, or pruinose violet with maturity. However, is set apart from the rest by the combination of (1) occurring locally at rainforest pools from DRC to Cameroon; (2) labrum, entire venation and Pt black, rather than pale and yellow to red respectively; (3) Abd very broad, S4 under 2x as long as wide (best seen in ventral view), with S8-9 largely black and S5-7 with latero-apical black markings.

Standing and often temporary waters, mostly in open areas in forest. Often with coarse detritus, a gravelly and/or soft (like muddy) bottom, and probably emergent and aquatic vegetation. From 100 to 1400 m above sea level.
