Pair of striated structures on the pedicel as in 
S. glohosa, where they were interpreted by 
Hickman (1931) as lyriform organs and by 
Petrunkevitch (1933) as stridulating organs.

Three claws, the median one being long, 
sharp and downcurved, and larger than the 
paired ones. The median claw on legs I and II 
has one tooth ; all the other claws are without 
pectinations. A few serrated bristles on the 
feet. No spines, but a large erect bristle 
towards the distal end of each patella, two 
smaller ones on tibia I, and one on tibia II. 
One trichobothrium on metatarsi I and II, 
three on tibiae I and II, two on III, and four 
on tibia IV. 
Abdomen: Length 0.88 mm., breadth 0.56 
mm. Pear-shaped with a rounded posterior 
end. The six spinnerets are ventrally placed, 
the anterior being the largest. Anal tubercle 
widened transversely. No colulus. Epigyne in 
the form of a transverse furrow overhung from 
in front by a rounded lip. Internal structure 
MALE: Length 0.76 mm. Carapace, sternum, 
and mouth parts brown, legs light brown. 
Abdomen light yellowish-brown, posterior 
end black. Anterior part of the sides slightly 
darker, there being a very faint suggestion of 
a dorsal band joining these areas. More well 
marked are two triangular dark areas anterior 
to the posterior black cap. Together they 
form a procurved crescentic dark marking, 
interrupted in the mid-dorsal line by the 
yellowish-brown ground colour of the ab- 
domen. 
Carapace: Length 0.30 mm., breadth 0.31 
mm. Sloping up steeply to the conspicuous 
row of eyes. Anterior to the eyes is a sinuous 
ridge, concave above the chelicerae and curv- 
ing forward in the middle line. This has the 
appearance of being the anterior edge of the
