"Platythomisus" is a genus of flattened crab spiders (family Thomisidae) from Africa and Southern Asia.

All species are only known from females or juveniles, with the exception of "P. jucundus", where only the male is known. [Platnick 2008]

Description

Females reach a body length of about 20 mm, males grow up to four mm. The smooth, convex cephalothorax is quite large, with smooth, slender legs that are not particularly long. The legs are often free of spines, with the occasional exception on the first two pairs. The opisthosoma is stout and oval.Murphy & Murphy 2000]

"P. octomaculatus" has a yellow-orange color with four round, black marks on the cephalothorax and seven large black marks on the opisthosoma, with one spot near the cephalothorax, and the other six following behing in two longitudinal rows. The legs are of a bright yellow, with the outer halves black.

Biology

"P. octomaculatus" is a rather rare species. One of the plants it has been found on is the yellow "Hibiscus tiliaceus". In captivity it was observed to feed on bees.
