First leg much the heaviest. Spines: Femur, 
none on I, other legs with a distal dorsal pair 
and two single proximal ones. Tibia; I, three 
ventral pairs, IV, one prolateral distal. Me- 
tatarsus; I and II, three ventral pairs, III and 
IV with one prolateral distal. 
Abdomen: Length 2.72 mm., breadth 0.96 
mm. Long and cylindrical. Anterior spinner- 
ets stout and parallel, the remainder slender 
and radiating, arranged in a line dorsal to the 
bases of the anterior ones.

male. Length 7.84 mm. Carapace chestnut 
brown, darker round the edge, with black 
surrounding the eyes but not in the ocular 
area. Chelicerae, palps, lip, maxillae, and leg 
I, except the tarsus, chestnut brown. Other 
legs and tarsus I, pale. Abdomen pale with 
narrow longitudinal grey streaks along the 
sides, interrupted by three oblique pale areas, 
leaving three roughly triangular pale areas on 
the dorsal side which decrease in size back- 
wards. The anterior dorsal area has two grey 
streaks along it. 
Carapace: Length 3.78 mm., breadth 3.00 
mm. Rounded in outline. Small longitudinal 
thoracic groove behind the PLE about one- 
third the distance towards the posterior 
margin.

Eyes: Ratio of eyes AM:AL:PL:PM 
= 142:85:85:26. Ratio of their distances apart 
AM-AM, 10; AM-AL, 27; PM-PM, 406; 
PL-PL, 382; AL-PM, 91; PM-PL, 73. Breadth 
of anterior row of eyes 2.32 mm. 
Chelicerae: Stout, convex on the outer (dor- 
sal) margin where there is a dark ridge, and 
somewhat concave anteriorly on the prolateral 
surface. Prolateral margin of the groove with 
two teeth at its ventral end, from which a 
dark ridge runs along the ventral margin. In 
the retrolateral margin of the groove there 
is a concavity in the dorsal half and a large
