Only 2 species in this Genus. 1 species in Philippines and 1 in Borneo Island.

Genus Mantisatta spiders are flat with long slender bodies.
 

The femora, patellae and tibiae of legs 1 are proportionately very large. Compared with all other leg segments make legs 1 much the longest and powerfully strong.  There are some short, strong spines ventrally on the tibiae and metatarsi of legs 1.

On legs I of the male the femora, patellae and tibiae are dark  brown and the tarsi are yellow. The remaining pairs of legs are yellow.

The abdomen is very elongate, almost parallel-sided, widely truncated at the front and has a long pointed tail which extends a long way past the spinnerets.

The cephalothorax (head segment) is thin and flat.

The carapace (upper section)  is oblong, almost twice as long as wide, with slightly curved sides.

A carapace is a dorsal (upper) section of the  cephalothorax (head segment)

This is a male judging from its final segment of the pedipalp, the tarsus, shaped swollen like a bulb.
