Eleuthemis eogaster Dijkstra, 2015
Type locality: Lumanie River near Quitoque,, Angola
Male is morphologically like E. buettikoferi by (a) the moderate size, Hw 25.2-26.5 mm (n = 3); (b) the distinct black border to labrum; (c) Fw with darkened tip that just touches distal end of Pt; (d) the Fw discoidal field entirely of two or more rows of cells; (e) the largely orange underside of the abdomen; (f) the largely blackish secondary genitalia; and (g) the acute tip to the hook of the hamule. However, (1) the middorsal section of the mesepisterna is brown, distinctly lighter than the blackish lateral thoracic stripes, thus contrasting weakly with the pale antehumeral stripes; (2) the largely bright orange abdominal dorsum is unique, with S2-3 bearing basal brown smudges, S4-5 pairs of dark subbasal spots, S6-8 two sublateral black bands, while S9-10 are (largely) black, and the dark markings on S4-6 and sometimes base of S7 become covered by white pruinosity with maturity; and (3) the cerci are orange at their base, contrasting with the largely to wholly black epiproct.

Mostly rivers, but also streams, shaded by or in open areas in forest. Especially faster sections, usually with overhanging branches, submerged roots and/or probably dead trunks or branches and a gravelly and/or sandy bottom. From 600 to 1200 m above sea level.
