Description
Size (female): length 8.0 mm.

The proportional lengths of the cephalothorax and abdomen are as 2.8 to 1.0. The head is separate from the 1st thoracic segment and thoracic segments 4 and 5 are also separate. The forehead shows a rounded curve with no traces of any median frontal spine. The posterior thoracic margin is produced backwards in a triangular plate that terminates in a short spine-like projection. The rostrum is strong and each spine terminates in a fine flagellum. The abdomen consists of four segments. The genital segment presents a uniformly rounded swelling ventrally; the ventral surface, posterior to the genital orifice, bears scattered hairs, and there is a patch of small scattered hairs on the lateral aspect. The furcal rami are fringed with hairs on their inner and ventral aspects, and dorsally are armed with short rows of needle-like spines. Abdominal segments 1 to 3 inclusive are either fringed with very fine hairs on their posterior aspects or else the marginal cuticle is finely striated. Both dorsal and ventral aspects of these segments are covered wih transverse row of minute scale-like markings from most of which a minute hair still projects.
