Chickering — -Genus Scaphiella 
151 
of each chelicera there arises a long, slender spine and two curious, 
black structures similar to those recorded in 1951 for S. barroana 
Gertsch. Maxillae apparently typical of males of the genus. Lip: 
triangular and essentially typical of males of the genus. Sternum: 
convex as usual, without grooves or lobes; longer than wide in ratio 
of about 8:7; terminated opposite bases of fourth coxae which are 
separated by about 1.33 times their width. Legs essentially typical of 
the genus. Palp : essential features shown in Figures 36-38 ; both 
palps fully developed ; no prolateral striations observed on palpal 
tarsi. Abdomen: slender; 0.72 mm long exclusive of the slightly ex- 
posed pedicel; about 0.36 mm wide two thirds of its length from 
base; with a considerable area not covered by scuta (Fig. 39); the 
sclerite partly surrounding the spinnerets as usual in the genus. Color 
in alcohol : parts of abdomen not covered by scuta white ; all other 
parts of body and appendages light yellowish with variations. 
Female paratype. Total length 1.63 mm. Carapace 0.55 mm 
long; 0.42 mm wide opposite second coxae where it is widest; 0.2 1 
mm tall; gently arched from PME along middorsal region to be- 
ginning of steep posterior declivity; otherwise essentially typical of 
females of the genus. Eyes essentially as in male. Chelicerae, con- 
vergent maxillae and triangular lip all essentially typical of females 
of the genus. Sternum : convex as usual ; longer than wide in ratio 
of 6 : 5 ; faintly tabulated along margin ; squarely truncated between 
bases of fourth coxae which are separated by 1.6 of their width. Legs 
essentially as in male. Abdomen: in general essentially typical of 
females of the genus; with single scutum as shown in Figure 40; 
considerably compressed laterally; epigynal area obscurely distinctive 
(Fig. 41). Color in alcohol: unshielded area of abdomen white; 
scutum somewhat darker than in male; otherwise essentially as in 
the holotype. 
Record. The described female paratype together with one other 
female taken during the same period as that in which the holotype 
was collected.

Holotype. The male holotype is from Trinidad, W. I. Arima 
Valley, Simla, April 19, 1964. The name of the species is a noun 
used in apposition after the locality where the holotype was collected. 
Description. Total length 1.76 mm. Carapace 0.7 mm long; 0.55 
wide opposite second coxae where it is widest ; about 0.26 mm tall ; 
very gently arched from PME to beginning of moderately steep 
posterior declivity which is quite granulate; ventral margin also 
granulate; otherwise essentially typical of the genus. Eyes: six as
