ABOUT THE GENUS

This genus of running spider is rather unique among the South African known genera. With their long, thin bodies, and their legs not being too long, Tibellus spiders are masters of camouflage. They live on and make their egg sacs in grass where they’re most protected.

For this lady, it was a matter of the long body and the leg formation typical of running spiders that pointed me to the genus Tibellus. Then it was off to the literature to find her species.

And, thanks to a revision in the Afrotropical species of Tibellus, I was able to narrow it down using the drawings, then reading through the descriptions of each species to find the one that fit. And that is Tibellus sunetae mainly for the dorsal markings, the spots, and the leg formation along with colouration.
