Female

The oval body, which narrows considerably toward the anterior end and is broadest opposite the spiracle, measures 1.75 x 1.2 mm in the smallest unfed specimen
The dorsum is strongly hairy and Sudan-brown, featuring a complete marginal groove in unfed females that disappears upon feeding, and an anal groove with sub-parallel limbs that meet in a regular curve anterior to the anus and extend shallowly to the posterior body margin
The scutum is longer than it is broad, ranging from 1.2–1.5 mm in length and 0.8–1.1 mm in breadth
The capitulum (0.75–0.9 mm long) has a sub-triangular base, short and obsolescent cornua, and very large porose areas separated by half their largest diameter
The palps are four times as long as they are broad with sub-equal articles II and III, where article II bears four very small, simple hairs on its supra-internal margin
The anteriorly long and pointed hypostome features an obsolete corona and is armed with 2/2 to 3/3 rows of approximately 11 unequal teeth, while the external cheliceral article possesses a long, sigmoid-shaped dorsal process and six cusps that progressively increase in size from the distal to the proximal end.
