 [B & H] Female: Small species. Caudal ramus just longer than anal somite. Ventral hook of genital double-somite weak; produced ventral margin of genital double-somite almost rectangular in lateral view. Male: Genital somite only as long as anal somite and caudal rami combined. [V & S] Female: Posterior points of thoracic segment 3, in dorsal view, scarcely reacing half genital segment. Spine of basipodite 2 of A2 less than half of spine of basipodite 1. Male: Posterior points of thoracic segment 3, in dorsal view, shorter than 2/3 genital segment. Genital segment length scarcely shorter than caudal rami. Genital segment 1.5 times longer than caudal rami.

Nota : Cephalothorax and abdomen in the proportional lengths 69 to 31. Head separates from the 1st thoracic segment, but the line of demarcation is very feeble.w Wing-like expansion of the 3rd thoracic segment extends only to the level of the proximal 1/5 of the genital segment. 4th thoracic segment ends into short pointed processes. Abdominal segments and caudal rami in the proportional lengths 45 : 27 : 28 = 100. Proximal part of the genital segment dilated, without ventral hook. Anal segment 1.4 times as long as it is broad at the anterior border.
