Azuragrion granti (McLachlan, 1903)
Socotra Bluet

Type locality: Socotra, Yemen

Diagnosis

Male is similar to other Azuragrion species by (1) Hw 11-15 mm; (2) mesostigmal plates without dorsally raised flap- or knob-like ridges; (3) base of paraproct scarcely swollen. However, species set apart from the rest by (1) restricted to Socotra Island; (2) relatively larger size, Hw 20-22 mm; (3) metapleural and interpleural sutures with black stripes along much of their length; (4) antehumeral stripe connected posteriorly to blue on mesepimeron; (5) only S9 largely blue, rather than both S8 and 9.
