For some time the holotype of this species was, with some un- 
certainty, placed with S. Simla sp. nov. After re-examination and 
comparison the decision has been made to regard it as the representa- 
tive of a new species as presented here. This decision has been made 
on the basis of several minute differences, the most important of 
which are the following: it is considerably smaller than S. Simla sp. 
nov. ; the ALE are barely separated ; the palpal femur is relatively 
shorter and more inflated ; the palpal patella and tibia are relatively 
longer. The female paratype is plainly quite different from the fe- 
male of S. simla sp. nov. 
Description. Total length, including somewhat extended spin- 
nerets and bases of chelicerae, 1.23 mm. Carapace 0.48 mm long; 
O.42 mm wide opposite second coxae where it is widest; about 0.13 
mm tall ; somewhat arched from PME to beginning of steep posterior 
declivity; without a median thoracic groove or pit. Eyes: six in 
two rows and in a compact group as usual; posterior row slightly 
procurved, measured by posterior borders and seen from above. Ratio 
of eyes ALE : PME : PLE = about 6.5 : 5.5 : 5 (some dis- 
tortion, PLE not clearly outlined). ALE barely separated; con- 
tiguous to PLE and separated from PME by less than half their 
width (Fig. 48). PME contiguous to one another and to PLE. 
Height of clypeus nearly equal to diameter of ALE. Chelicerae, 
maxillae and lip apparently typical of males of the genus. Sternum: 
convex as usual ; moderately lobed along lateral margins ; longer than 
wide in ratio of about 10 : 9; posterior end bluntly rounded and ex- 
tended between fourth coxae which are separated by five-thirds of 
their width ; third coxae globose, all others somewhat elongated. 
Legs: probably 4123 in order of length (fourth legs missing) ; tibial 
index of first leg 10; no true spines observed. Palp: general features 
typical of males of the genus; Figures 49-51 show essential features; 
lateral tuft of modified hairs present but obscure. Abdomen : with 
typical scuta covering all but extreme posterior end and a narrow 
strip between dorsal and ventral scuta.; genital aperture a minute, 
circular opening; otherwise typical of males of the genus. Color in 
alcohol : carapace, sternum and abdominal scuta a light yellowish 
brown; legs and mouth parts yellowish except palpal tarsus which 
is nearly white. 
Female paratype. Total length 1.8 mm, including considerably 
extended chelicerae and spinnerets; exclusive of these parts, total 
length is 1.63 mm. Carapace 0.64 mm long; 0.48 mm wide opposite 
posterior border of second coxae where it is widest; about 0.19 mm 
tall ; only slightly arched along middorsal region to beginning of steep
