Description
Size: Length: 1.76-2.26 mm (female); 146-1.83 mm (male).

In females, body is broad, cephalon with lateral hooks, dorsal eye lenses are small. Thoracic segment rounded posteriorly. Lateral posterior margin of metasome rounded, but extended on the right side with a ventrally pointing spine; left side without any spine; urosome 3-segmented, genital segment elongated and half the length of urosome; right anterior and also posterior corner of genital segment with lateral swellings, in the proximal centre of the ventral surface is a small chitinous outgrowth. Right ventral surface of urosome and second urosome segment with chitinous knobs along right margin; furca asymmetrical, right side larger. Exopodite bifurcated at tip; the endopod is normally bent outwards over the exopodite, short, broad based and ends in an apical spine plus a rather shorter spine on the inner margin. Two minute spines on outside margin of exopod (Greenwood, 1979) or one spine (Silas and Pillai, 1973).
In males, body is elongated, dorsal eye lenses are prominent and contiguous. Urosome is 5-segmented and naked, genital segment broader than long, with a small lobe at the right posterior margin. Last metasome segment asymmetrical, shorter point on left, extended into a longer flat curved tip on right. Terminal segment curved, with 3 setae along internal margin and two seta distally. Left leg terminal segment with at least 3 lobe-like processes.
