Cyclasterope bisetosa Poulsen, 1965:301, figs. 102, 103, 104.

HOLOTYPE.—Ovigerous female in Copenhagen Museum.

TYPE-LOCALITY.—Dana station 3839, Padang Harbor, west coast of Sumatra. Shallow water less than 50 m depth (Poulsen, 1965:306).

MATERIAL.—None examined.

DISTRIBUTION.—West coast of Sumatra, southeast coast of Thailand (50 m).

DIAGNOSIS OF ADULT FEMALE.—Carapace with short hairs longer and more abundant than on Cyclasterope fascigera. Posterior of carapace with angle near middle. Surface appearing white, porcelaneous. Length of adult female 5.8 mm (only 1 mature female known).

First Antenna: 2nd joint with 7 or 8 dorsal bristles and 1 lateral bristle. 3rd joint with single ventral bristle two-thirds the length of ventral margin of 4th joint. 5th joint: sensory bristle with 2 short proximal and 14 long terminal filaments. 7th joint: a-bristle clawlike, not pectinate.

Second Antenna: Endopodite: 1st joint with 18 bristles (some proximal bristles quite long); 2nd joint with 1 short bristle; 3rd joint with 1 short and 1 very long bristle.

Mandible: Basale: dorsal margin with total of 26 bristles. Endopodite: 1st joint longer than 2nd.

Fifth Limb: Dorsal margin of comb with 15 or 16 bristles.

Sixth Limb: With 5 epipodial bristles.

Seventh Limb: With 200 marginal bristles.

Furca: Each lamella with total of 14 claws and bristles; claws 4–7 with lateral bristle near anterior corner of bases (Poulsen, 1965:305, stated that the furca has lateral bristles off claws 5–7, but on p. 308 stated that the bristles are off claws 4–7). Poulsen (1965:305) stated that the furca of C. bisetosa is similar to that of C. fascigera, but the furca of the female of the latter species bears lateral bristles adjacent to claws 4–8 (Poulsen, 1965:294).
