margins; continued laterally between coxae and extended between 
fourth coxae which are well separated. Chelicerae, maxillae and lip 
without conspicuous modifications; no teeth observed along fang 
groove. Eyes: six in two rows with posterior row more or less 
recurved; figures accompanying descriptions show relative positions 
of eyes. Male palp simple except for tarsus which appears to have 
quite distinctive features. Legs moderately long and slender with 
few spines. Abdomen: ovoid in general; quite tall; dorsal scutum 
well developed but somewhat variable in size; epigastric scutum 
surrounds the pedicel and extends dorsally a considerable distance 
and also varies in size in different species; ventral scutum also 
quite variable in size in different species; epigynal areas obscurely 
distinctive. Carapace, sternum and abdomen with numerous short 
hairs.

Holotype. The male is from Simla, Arima Valley, Trinidad, 
W. I., April 25, 1964. The name of the species is an arbitrary 
combination of letters. 
Description. Total length about 1.81 mm (abdomen and cephalo- 
thorax detached but both parts in good condition). Carapace 0.86 
mm long; about 0.65 mm wide opposite second coxae where it is 
widest; about 0.29 mm tall; gently arched from PME along mid- 
line to beginning of moderately steep posterior declivity opposite 
third coxae; ventral margin smooth. Eyes: six in two rows; 
posterior row slightly recurved; eyes occupy only slightly more than 
half the width of carapace at that level (Fig. 1); irregularities in 
outlines of eyes appear to be present. Ratio of eyes ALE : PME : 
PLE = about 10 : 7.5 : 9. ALE separated from one another by 
about three-fifths of their diameter; barely separated from PLE; 
separated from PME by three-tenths of their diameter. PME 
contiguous only at their posterior ends and somewhat divergent 
anteriorly; narrowly separated from PLE. Height of clypeus 
slightly more than three-fifths of the diameter of ALE. Chelicerae: 
of moderate size; vertical; parallel; no teeth observed along fang 
groove. Maxillae: only slightly convergent; without conspicuous 
modifications; of moderate length. Lip: somewhat triangular in 
shape; about two-thirds as long as maxillae. Sternum: convex; 
distinctly lobed along margins; slightly widest between second coxae; 
longer than wide in ratio of about 11: 10: terminated just before
