Eleuthemis libera Dijkstra & Kipping, 2015
Type locality: Negage, Angola
Male is superficially similar to E. buettikoferi by the abdomen being (a) entirely whitish pruinose on the upperside with maturity; and (b) largely orange on the underside. Differs from other Eleuthemis species by (1) the pale labrum with at most a hint of a black border; (2) the pale frons darkened basally at least anteriorly to the lateral ocelli; (3) the uniformly brown occipital triangle; (4) the dark metapleural stripe expanded markedly onto the metepisternum between the metastigma and wing bases, rather than being of fairly even width throughout; (5) the Fw discoidal field with 2 to 5 single cells, rather than entirely of two or more rows of cells, although rarely up to 4 are single in others; (6) the largely pale brown rather than blackish secondary genitalia; (7) the relatively large and less divergent posterior branch of the genital lobe; and (8) the hook of the hamule with a right-angled rather than acute tip. Also notable are (9) the modest size, Hw 23.0-24.0 mm (n = 4) rather than 23.5-26.5 mm (n = 10); and (10) the dark tips of Fw that extend almost halfway along Pt, rather than just touching its distal end.

Streams shaded by gallery forest. Especially faster sections, usually with overhanging branches and/or submerged roots, and mostly a gravelly and/or probably sandy bottom. From 1100 to 1400 m above sea level.
