Paragomphus cataractae Pinhey, 1963
Cataract Hooktail

Type locality: Vict[oria]. Falls, Zambia/Zimbabwe

Diagnosis

Male is similar to P. sinaiticus by (a) being widespread; (b) size, Hw 22-26 mm; (c) labrum pale, at most vaguely darkened at base; (d) Pt brown, not contrasting with black veins; (e) apice S8-9 with broad foliations s of cerci parallel or apposed (dorsal view); (f) cerci slender, at least 1.5x as long as S10; (g) epiproct longer, almost as long as S10 or longer, not so strongly curved upwards; (h) cerci without distinct ventral ridge; epiproct about 1/3 as long as cerci. However, differs by (1) thorax uniformly bright green rather than yellow to green, and at most with indiscernible brownish markings on mesepisternum; (2) apical half of cerci very long and thin, with truncate apex bearing long tooth.
