Ischnura evansi Morton, 1919
Desert Bluetail
Type locality: Basra and Amara, Iraq
Diagnosis
Male differs from other Ischnura species by Fw Pt having an all dark centre with pale rim, rather than being sharply two-toned. Ranging only from Djibouti to Egypt within Africa, differs from I. abyssinica and I. senegalensis by (1) dorsal black on S2 of rather even width throughout, rather than being narrower at apex; (2) paraprocts as long as cerci, rather than longer. May be cinfused with I. fountaineae in Egypt. [Adapted from Dijkstra & Clausnitzer 2014]
