Patellapis (Chaetalictus) renosterveldi sp. n. Timmermann

( Figs. 101a–g ; 102a–h )

Diagnosis. The female is similar to those of P. minima and P. sakagamii . P. minima differs from P. renosterveldi in having the surface of scutellum completely reticulate (appears to be dull), whereas this part of the body is shiny and hardly reticulate in P. renosterveldi . P. sakagamii can be distinguished from P. renosterveldi by the reddish metasomal terga T2–T4. The male of P. renosterveldi can be distinguished from those of P. spinulosa , P. timpageleri and P. minima by the size and structure of the dorso-lateral projection on the inner side of the gonostylus. This projection is linear and slender, with a few long, strong, curled hairs ventrally, whereas P. spinulosa and P. timpageleri possess a small, hyaline projection with long, fine hairs ventrally. P. minima lacks such hairs on the dorso-lateral projection of gonostylus. The males of P. sakagamii and P. pulchrinitens can be easily distinguished from that of P. renosterveldi by having a polished face.
