Holotype. The male holotype is from Barro Colorado Island, 
Panama Canal Zone, January 15, 1958. The name of the species is 
an arbitrary combination of letters. 
Description. Total length 1.65 mm. Carapace 0.73 mm long; 
0.65 mm wide opposite interval between second and third coxae where 
it is widest; about 0.28 mm tall in cephalic region where it is tallest; 
without cephalic lobes or humps. Eyes: eight in two rows; nearly 
typical in general in those species without cephalic modifications; 
viewed from above, anterior row gently recurved and posterior row 
slightly procurved. Central ocular quadrangle nearly as long as wide 
behind; wider behind than in front in ratio of nearly 17 : 10. Ratio 
of eyes AME : ALE : PME : PLE = nearly 4:7 : 7 : 7 (long 
diameters always used when eyes are oval). AME separated from 
one another and from ALE by nearly five-eighths of their diameter. 
Laterals contiguous. PME separated from one another by five- 
sevenths of their diameter and from PLE by a little less than this 
distance. AME separated from PME by a little less than the 
diameter of the latter. Height of the clypeus slightly less than four 
times the diameter of AME. Chelicerae, maxillae and lip all typical 
of the genus and without observed modifications. Sternum: convex; 
slightly wider than long opposite interval between first and second 
coxae; extended between fourth coxae and squarely truncated; fourth 
coxae separated by about seven-fifths of their width. Legs: 2143 in 
order of length ; several long, slender spines observed but exact num- 
ber and placement not recorded. Palp: essential features shown in 
Figures 27-29. Abdomen: typical of males of the genus; with no 
special modifications observed. Color in alcohol: carapace light yel- 
lowish-brown with faint darker streaks; with considerable very dark 
brown pigment in ocular area; sternum very light grayish; legs and 
mouth parts yellowish with variations; palpal tarsus yellowish-brown 
with many variations ; abdomen light yellowish in general ; a narrow, 
indefinite, median, grayish stripe extends along the dorsum from 
base for about half the length of this part of the body; about five or 
six narrow, transverse, grayish bands cover the posterior half of 
the dorsum; faint grayish patches occur on the lateral sides and the?
