Ohilimia is a spider genus of the Salticidae family (jumping spiders).
Description
O. albomaculata reaches a body length of 7 to 8 mm, while O. scutellata is 5 to 7 mm long. The cephalothorax of O. albomaculata is densely covered with short hairs, O. scutellata is only sparsely covered. The sexes are similar, with males having distinctive shiny scuta. The first, elongated pair of legs is held in a mantis-like manner. It seems that Ohilimia mimic flies in reverse: their first legs are held like the wings of a fly, and they move backwards.[1]
Relationships
Ohilimia is probably closely related to Diolenius and Chalcolecta, which also have elongated front legs.
Distribution
Ohilimia only occurs in rainforests of the northeastern Cape York Peninsula of Australia, New Guinea and the Moluccas islands Ternate and Kai. The current distribution seems to be due to past land bridges.
