row distinctly recurved and occupies about eight-elevenths of width 
of carapace at that level. Very little difference in size of eyes but 
with ALE slightly the largest. ALE separated from one another 
by nearly three-fifths of their long diameter; barely separated from 
PLE and separated from PME by a broad line. PME contiguous 
to one another for nearly one-third of their circumference and sep- 
arated from PLE by a broad line. Height of clypeus appears to be 
somewhat less than the radius of ALE. Chelicerae, maxillae and 
lip : apparently quite typical of males of the genus with no special 
modifications observed. Sternum: moderately convex; surface smooth 
and with few hairs; longer than wide in ratio of nearly 4:3; ex- 
tended between bases of fourth coxae which are separated by nearly 
their width ; posterior end with a small cluster of erect, stiff hairs. 
Only fourth legs retained; these are moderately long and slender; 
apparently with a few slender, transparent spines. Palp: quite dis- 
tinctive; essential features shown in Figures 33-34; the cymbium is 
unusually short. Abdomen: somewhat taller than cephalothorax; no 
ventral or epigastric scutum observed ; entire abdomen soft and with 
little chitinization. Color in alcohol : with a moderate amount of 
black pigment in ocular region; all other parts of cephalothorax, 
legs and mouth parts light yellowish with little variation; abdomen 
almost white throughout. 
Diagnosis. The general features of the carapace and eyes seem 
to ally this species with such already recognized species as Oonops 
persitus sp. nov. from the Panama Canal Zone. The distinctive 
features of the male palp, especially the tarsus, definitely establish 
it as a new species.
