Thomisus dalmasi

Thomisus dalmasi is a crab spider that exhibits the typical body plan of the family Thomisidae. Like other members of the genus Thomisus, it has a flattened cephalothorax and opisthosoma, with legs that can be held sideways in a crab-like manner. Both males and females of the species are known, with the female typically being larger than the male, as is common in spiders. The species can be distinguished from other Thomisus species by specific characteristics of the male pedipalps and female epigyne, though detailed morphological descriptions require microscopic examination.

Thomisus dalmasi has been recorded from eight African countries: Guinea, Cameroon, Democratic Republic of the Congo, Rwanda, Tanzania, Malawi, Mozambique, and South Africa. In South Africa, the species is known from seven provinces and has been found in seven protected areas.
