See text.

Cosmophasis is a genus of spiders in the family Salticidae (jumping spiders). They are predominantly Southeast Asian,[2] while some species occur in Africa and Australia . Although most species more or less mimic ants, there are also colorful species[3] that follow a different strategy.

C. bitaeniata uses chemical mimicry to be accepted by the aggressive weaver ant species Oecophylla smaragdina.[4]

One species, said to be not a particularly good ant mimic, was observed living near and preying on ants. According to (Murphy & Murphy, 2000), "to watch the spider stalking and killing its prey is an arachnological spectacular".[5]

Description

Species in this genus are from 3.80 to 8.00 mm long. The cephalothoraxes are pear-shaped(for some males) or rectangular. [6]
