Paragomphus magnus Fraser, 1952
Great Hooktail

Type locality: Mombasa, Kenya

Diagnosis

Species not particularly close to any other Paragomphus species, but similar to most by (a) cerci slender, at least 1.5x as long as S10; (b) apices of cerci parallel or apposed (dorsal view); (c) epiproct longer, almost as long as S10 or longer, not so strongly curved upwards. However, P. magnus is set apart from the rest by (1) ranging from Kenya to Mozambique and Zimbabwe; (2) relatively large in size, Hw 28-33 mm; (3) labrum black with broad contrasting pale border; (4) Pt black rather than pale to brown; (5) S8-9 appear to lack foliations, these extremely narrow.
