Compared with other species:
- Similar to Flapper Hooktail, Paragomphus sabicus, Gomphidia quarrei (Southern Fingertail) Ictinogomphus ferox (Common Tigertail) Onychogomphus supinus (Lined Claspertail) and P. sabicus (Flapper Hooktail).
- Differences in the claspers. O. quarrei has no foliations and short slender upper appendages with a very short lower appendage. O. supinus have inferior appendages that are very fine, upwardly curved with two fine prongs when viewed from side. I. Ferox has inferior (lower) appendages that curves upwards to tough the superior appendages and large foliations below S 8. P. magnus has very large superior appendages with the tips curving back to almost face S10 and no foliations. P. sabicus has superior appendages that are long, slender and gently curved, yellow with brown tips.
- Foliations on P. selysi distinct
- The abdominal stripes, dorsal thorax and the markings on the side of the thorax are diagnostic in the mentioned species
Distribution and habitat:
- Rare in South Africa, having only been recorded a few times in the northern region of KZN, MP and LP
- Mostly rivers, but also large lakes and streams and possibly flowing channels in marshes, in open landscapes, open areas in forest or shaded by gallery forest. Often with a sandy and/or soft (like muddy) bottom. From 0 to 1400 m above sea level.
