Ceriagrion sakejii Pinhey, 1963
Cream-sided Citril

Type locality: Mwinilunga, Zambia

Diagnosis

Male is typical of suave-complex of genus by (a) the moderate size, Hw 17-23 mm; (b) greenish eyes with maturity; (c) uniformly orange to red abdomen; (e) apically pointed penis; (f) no toothed processes on the apical border of S10; and (g) paraprocts that do not reach beyond the cerci and that have a fairly distinct angular heel ventrally. Easily distinguished by (1) being confined to boggy habitat from N Zambia to Katanga and Angola; (2) the thorax with distinct blackish dots in the humeral and metapleural fossae and a sharp contrast between the warm orange brown dorsum and creamish sides; (3) the penis with finger-like lateral lobes, rather like C. bakeri; (4) the dorsal excision of S10 with pale and somewhat thickened and raised borders that bear a distinct gap between them medially; and (5) the notably short cerci that appear almost round in dorsal view.
