I found this little tid-bit of info on Platysaurus torquatus:
This small platy is the only species in the genus in which males retain the pale longitudinal stripes and females and juvenils have uniform Cambridge blue tails. It has opaque lower eyelids, each divided by a series of vertical septa. The supranasals are fused with the nasals. The middle row of gulars is not very enlarged. The scales on the sides of the neck are flattened and enlarged, and those on the flanks are larger than those on the back. The ventrals are in 16-20 longitudinal rows. Males have 18-20 femoral pores. Females and juvenils have a blackish-brown back, with three buff stripes with a few or no spots between them. The tail is blue with a dark median stripe. The throat and chest are white, and the belly and base of the tail are orange. Adult males have a dark brown back with three buff stripes. The flanks and tail are bright orange. The limbs are grey-brown. The throat is white, with a black collar. The chest is orange or yellow, suffused with bright green, and becoming Prussian blue on the belly. Biology : Gregarious on flat outcrops, particualarly along river courses. Feeds on ants, beetles and some catepillars. Two eggs (19x7 mm) are laid in December. Habitat : Mesic savannah. Range : NE. Zimbabwe extending into west-central Mozambique and S. Malawi.
