Genus Ictinogomphus Cowley, 1934
tigertails
Synonyms:
- scientific: Cinitogomphus Pinhey, 1964 [dundoensis]
Type species: Ictinus ferox Rambur, 1842
Introduction
Over 15 species are known, ranging east to Australia, four occur in Africa: I. dundoensis was formerly in a separate genus Cinitogomphus. Males are very large (hindwing 38-51 mm) black-and-yellow dragonflies that perch conspicuously on prominent stakes over water, raising abdomen to display the distinctly foliated end. Unlike most gomphids they favour calm water: I. ferox occurs at marshes, ponds, lakes and calm rivers, I. dundoensis in marshy rivers like in the Okavango Delta, and I. regisalberti and its western counterpart I. fraseri at rivers, often in forest. [Adapted from Dijkstra & Clausnitzer 2014]
Diagnosis
Male of genus is similar to Diastatomma and Gomphidia by (a) dorsal border of metepisternum, close to Hw base, with robust spine; and (b) triangles of 3-4 cells; anal triangle of 5 cells, although rarely 4 to 7. However, Ictinogomphus differs by the distinct foliations on S8. [Adapted from Dijkstra & Clausnitzer 2014]
