Genusa simplex Warren 

Genusa simplex Warren, 1897, Novit. zool. 4: 88.

Diagnosis

This is the most strongly marked species in Borneo, indeed in the genus, with the mottled grey banding extensive as illustrated. A few specimens (including the holotype) are much more weakly marked.

Taxonomic Notes

The furca has the spining restricted to the apex of each arm; in most other species it extends down the shaft also. In material from Peninsular Malaysia and Sumatra the furca is shorter, each arm two thirds the length of that in Bornean specimens.

Geographical Range

Sulu Is. (S. Philippines), Borneo; Peninsular Malaysia, Sumatra.

Habitat Preference

The only recently taken specimen was from 300m in dipterocarp forest, Ulu Temburong, Brunei.
