Diversity: Five species described (recently revised by Miller et al. 2012): P. parva, P. presleyi, P. splendens, P. striatipes, P. variegata. The most of species were previously classified as Adonea, still mislabelled in some popular books.

Distribution: South Africa, Namibia, Botswana, Zimbabwe.

Appearance: Medium to big spiders with bigger eyes. Body gray, brown or black, with dots and markings. Coloration of adult males contrast, black and white. 

Biology: Based on personal experiences with P. variegata form Namibia. Lives in under stones in semi-desert or desert areas. On some places sheet of web excavating from the entrance to nest observed. Those sheets were about 5-10cm large, but hardly recognisable, because covered with sandy soil. Patchy distribution is characteristic for this species but “colonies” are less numerous than in Seothyra. Nest with bigger juveniles and females were observed during September number of youths was lower (20 and less, probably a dispersion started already). Matrhiphagy is presented. Males get adult in captivity during January or February, keeping their seasonality in captivity regardless condition of breeding. Seasonality seems to be typical for other species of the genus as well.
