Genus Nepogomphoides Fraser, 1952
Type species: Nepogomphoides pinheyi Fraser, 1952 [= stuhlmanni]
This monotypic genus is confined to forest streams in the mountains of eastern Tanzania, southern Malawi and northern Mozambique. N. stuhlmanni is recognised by its small size (hindwing 23-26 mm), black labrum with double yellow spots, and spectacular appendages. Probably the species is related most closely to Tragogomphus (see Libyogomphus) of western Africa. [Adapted from Dijkstra & Clausnitzer 2014]
Male of genus is similar to Libyogomphus by (a) labrum often black with two contrasting pale dots, which are sometimes merged; (b) posterior hamule terminates in single large tooth directed anteriorly; (c) anal triangle of 4 cells [3-6], and anal loop of 1-2 cells present; (d) hind femur shorter than breadth of head; (e) cerci strongly down-curved, with rather blunt apices; (f) epiproct as long as or longer than cerci, and at most with dorsal teeth near base; (g) branches of epiproct touch or lie close to each other, often bear dorsal process between base and apex. However, differs by (1) ranging from NE Tanzania to S Malawi; (2) cerci and epiproct both with dorsal teeth near base (lateral view).
