Paragomphus pumilio (Rambur, 1842)
Dwarf Hooktail

Type locality: Egypt, no locality data available.

Diagnosis

Male is similar to P. genei by (a) labrum pale, at most vaguely darkened at base; (b) Pt with maturity pale, contrasting with black veins; (c) S8-9 with broad foliations; (d) cerci slender, at least 1.5x as long as S10, apices of cerci parallel or apposed (dorsal view); (e) cerci with distinct ventral ridge; epiproct about ½ as long as cerci; (f) epiproct longer, almost as long as S10 or longer, not so strongly curved upwards. However, differs by (1) being restricted to rivers and lakes from N Kenya to Egypt; (2) smaller size, Hw 18-22 mm; (3) posterior hamule hook-shaped, its apex narrowed; (4) foliations all pale rather than dark-bordered; (5) cerci with smooth ventral ridge, apex blunt, with small subapical denticle.
