Description
Size: Length: female 1.65-1.75 mm; male 1.26-1.48 mm.

Female: Prosome 4-segmented. The lateral points at the end of the prosome do not extend as far as the genital segment. Urosome 2-segmented. The genital segment is large, oval, and about 1.3 times longer than wide. The posterior dorsal section of the genital segment overlaps the anal segment. The posterior margin of the ventral side of the genital segment with a row of minute spinules. The anal segment narrows slightly. Posterior margins of anal segment fringed with small spinules. Furca is divergent, about 6 times longer than wide, and about 3/5 the length of the urosome.
Male: Prosome narrower than in the female and 3-segmented. The outer lateral points at the end of the prosome extend to the centre of the genital segment. Urosome 2-segmented. Genital segment about 1.5 times longer than wide, oval, the lateral margins are smooth and each bear a plumose seta near the posterior end. The ventral posterior margin of the genital segment with a row of minute spinules. The posterior margin of the anal segment with a row of spinules along the join with the furca. The furca are parallel, about 8x longer than wide, and about ¾ the length of the urosome.
