Azuragrion somalicum (Longfield, 1931)
Somali Bluet

Type locality: Marojeh, Somalia

Diagnosis

Male is similar to A. vansomereni and A. nigridorsum by (a) size, Hw 11-15 mm; (b) metapleural and interpleural sutures with (almost) no black; (c) antehumeral stripe separated from mesepimeral blue by complete humeral black stripe. However, differs by (1) ranging from N Somalia, E Ethiopia and S Arabia; (2) postclypeus largely blue rather than black; (3) antehumeral stripe broader rather than narrower than halfwidth of mesepisternum; (4) dorsal black S3-7 narrow, rather than broad and continuous, and interrupted at bases of segments; (5) S8-9 all blue, rather than basally black; (6) cerci with long lower branch jutting out, therefore well visible; (7) paraprocts distinctly longer than cerci.
