than in male; sternal suture gently procurved; otherwise essentially 
as in male. Legs: 4123 in order of length as in male; slender, trans- 
parent spines seem to be present on legs as in male but it is difficult 
to distinguish between spiniform bristles and very slender spines. 
Abdomen: essentially as in male except that the scuta are even less 
distinct than in that sex; the epigynal area is very obscure but ap- 
pears to exhibit a few faintly indicated distinctive features (Fig. 9) ; 
the female paratypes generally show no epigynal features of distinction. 
Color in alcohol: the conspicuous mark on the posterior declivity of 
the male is much less distinct here in the female; the purple areas 
on the abdomen are lighter in color and the reticulation is much 
clearer than in the male; otherwise essentially as in the male; con- 
siderable variation of the color pattern has been noted among the 
paratypes. 
Diagnosis. This species also seems to be closely related to Oonops 
reticulatus Petrunkevitch. The features of the eyes, the obscure 
features of the epigynal area in the female paratype and, especially, 
the palpal tarsal features of the male establish it definitely as a new 
species. 
Records. The described female paratype was taken on the same 
day and in the same locality as the male holotype. Several paratypes 
of both sexes, some immature, were collected in the same general 
locality April 5-8, 1964.

Figures 10- 11 
Oonops zeteki Chickering, 1951: 229, fig. 17. The holotype female from 
Barro Colorado Island, Panama Canal Zone was taken in a Berlese 
funnel, July 1943-March 1944 by Dr. James Zetek and is now in the 
Museum of Comparative Zoology, Harvard University. 
The posterior row of eyes is only slightly recurved in this species 
and the carapace has a somewhat different shape than usual (Figs. 
10-11). The pedal spines are conspicuous and the epigynal area is 
without observed distinctive features. 
One additional female taken on Barro Colorado Island by Dr. 
Zetek in a Berlese funnel in 1946 and another female taken in the 
same locality August 16, 1954 are definitely placed in this species. 
4 hree females taken in Summit Gardens, Panama Canal Zone, July 
2 4> J 954 were for a time placed in this species but now their status 
is uncertain. The male remains unknown.
