Female:

  • Females are very similar, stouter, with yellow and less dark body markings.
  • Wings smokier especially in the basal area.
Compared with other species:
  • Similar to Icterogomphus ferox (Common Tigertail)100 1027 Ictinogomphus ferox Common Tigertail Male Close up Nwanedi LP RSA Dec 2018r 5 Paragomphus magnus (Great Hooktail)100 1784 Paragomphus magnus Great Hooktail Male Ndumu Mch 2017r 1 and Paragomphus sabicus (Flapper Hooktail). 100 1907 Paragomphus sabicus Flapper Hooktail Male Close up Ndumo KZN RSA Mch 2018r 1 The major differences are in the claspers with O. supinus having inferior appendages that are very fine, upwardly curved with two fine prongs when viewed from side 102 566 Lined claspertail r 2 102 567 Lined claspertail r 3I. Ferox inferior appendages curves upwards to touch the superior appendages. 100 1202 Ictinogomphus ferox Common Tigertail Male Close up Nwanedi LP RSA Dec 2018r 23 P. magnus has very large superior appendages with the tips curving back to almost face S10. 107 521 Great Hooktail 1 4
  • The abdominal stripes, dorsal thorax and the markings on the side of the thorax are diagnostic in the mentioned species.
  • P. magnus has no foliage’s, 100 1805 Paragomphus magnus Great Hooktail Male Ndumu Mch 2017r 2 I ferox has large dark foliations on s 8. 100 1202 Ictinogomphus ferox Common Tigertail Male Close up Nwanedi LP RSA Dec 2018r 23 P. sabicus has large foliations on s 8 with smaller on s 9.100 1916 Paragomphus sabicus Flapper Hooktail Male Close up Ndumo KZN RSA Mch 2018r 28
  • The white bands on the thorax and abomen markings of female O. supinus may easily be misidentified with Ceratogomphus pictus (Common Thorntail)
  • Thorax markings may be misidentified with Crenigomphus hartmani (Clubed Talontail) 100 1792 Crenigomphus hartmanni Clubbed Talontail Male Melkrivier LP RSA Dec 2017r 3
  • Differs from other Crenigomphus and Paragomphus by a 2 celled anal loop
  • Males have a distinctive inside tooth on the lowerclasper 102 566 Lined claspertail r 2
Distribution and habitat:
  • Found in KwaZulu-Natal, Mpumalanga and Limpopo Province with an isolated record in Gauteng Province.
  • Prefer rivers and streams in open areas in forest or shaded by gallery forest, especially faster sections (rapids, falls), usually with rocks. Occur from 100 to 1900 m above sea level, but mostly between 500 and 1700.
Behaviour:
  • Perches on boulders in the rivers and on grass stems on the bushy banks.
  • Female lives mostly away from the water and is therefore very rarely seen
