especially on first and second legs (Fig. 28). Palp: essential features 
shown in Figure 29; tarsal features quite distinctive. Abdomen: 
ovoid; without special modifications; epigastric and ventral scuta 
barely indicated. Color in alcohol: carapace light yellowish with 
pigment in ocular region as shown in Figure 27 ; legs like carapace 
above but lighter below; sternum very light yellowish and mouth 
parts essentially the same with some variations ; abdomen nearly 
white. 
Diagnosis. This species appears to be closely related to Oonops 
itascus sp. nov. from Trinidad, W. I. yith relationships as indicated. 
The features of the palpal tarsus definitely establish it as a new 
species. 
Records. One male paratype was taken with the holotype. The 
female is unknown. 
Oonops anoxus sp. nov.

Holotype. The male holotype is from Barro Colorado Island, 
Panama Canal Zone, May 17, 1964. The name of the species is an 
arbitrary combination of letters. 
Description. Total length 1.76 mm exclusive of the extended 
spinnerets; including these organs, total length is 1.91 mm. Cara- 
pace 0.79 mm long; 0.56 mm wide opposite second coxae where it is 
widest; nearly 0.30 mm tall; gently raised just behind PME and 
then nearly level along midline to beginning of moderately steep 
posterior declivity; surface smooth and shining; with a moderately 
well developed coat of dark hairs; with no evidence of a median 
thoracic groove or pit. Eyes: six as usual in a moderately compact 
group (Fig. 30) ; posterior row recurved and only a little wider than 
anterior row; posterior row occupies a little more than four-fifths 
of the width of the carapace at that level. Ratio of eyes ALE : 
PME : PLE = nearly 8.5 : 8 : 7. ALE separated from one 
another by slightly more than half their long axis; separated from 
PME by a little less than one-fourth of their long axis and from 
PLE by a narrow line. PME contiguous to one another for nearly 
one-third of their circumference and separated from PLE by nearly 
one-sixth of their long axis. Height of clypeus equal to nearly 
three-eighths of the long axis of ALE. Chelicerae, maxillae and lip 
all apparently quite typical of the genus; with no special modifications 
observed. Sternum : rather strongly elevated ; longer than wide in 
ratio of nearly 5:4; slightly lobed along margins ; rounded posterior
