Ceriagrion kordofanicum Ris, 1924
Little Orange Citril

Type locality: Sudan, no locality data available.

Diagnosis

Male is similar to C. ignitum by (a) size, Hw 15-17 mm; (b) labrum without transverse, ridge-like fold; (c) penis with pointed or finger-like lateral lobes; (d) cerci at most slightly longer than paraprocts, with at most small tooth near apex; (e) paraprocts often reach only as far as tips of cerci. However, differs by (1) ranging from South Sudan to Mozambique and Zambia; (2) head and thorax red rather than dark brown, Abd orange-red rather than deep red; (3) paraprocts with heel and ‘toe’ very prominent, ‘toe’ directed upwards pointing at midlength of cerci.
