Psyche 
[March-June 
Female paratype. Total length 1.43 mm. Carapace 0.65 mm 
long; nearly 0.46 mm wide opposite second coxae; nearly 0.27 mm 
tall; general shape as in male. Features of the external anatomy 
resemble those of the male so closely that a detailed description is 
regarded as unnecessary. The epigynal area appears to be quite 
distinctive (Fig. 5). 
Diagnosis. This species seems to be closely related to Oonops 
ronoxus from St. Croix, U. S. Virgin Islands. The male palp, the 
shape of the carapace and the epigynal area of the female seem to 
establish it as a new species. 
Records. The female paratype was taken in the same locality and 
within the same time period as the male holotype. There are no other 
paratypes.

Telchius placidus,- Bryant, 1942: 323, figs. 3-4. Not Oonops placidus Dal- 
mas, 1916. 
Oonops balanus Chickering, 1972: 204, figs. 1-11. New name for Telchius 
placidus Bryant. 
In addition to the distribution of this species as reported in Part 2 
of this series on the genus Oonops I seem to have numerous speci- 
mens from St. Kitts, Nevis and Antigua, B. W. I. and Jamaica, W. I. 
where it appears to be abundant. There are puzzling variations 
among these numerous specimens at present assigned to this species 
and further study may show that the collection includes more than 
one species.

Holotype. The female holotype is from Puerto Rico, W. I., 
Mayaguez, University campus; sifted from hay and weed debris 
January 11, 1964. The name of the species is an arbitrary com- 
bination of letters. 
Description. Total length 2.26 mm. Carapace 0.75 mm long; 
0.66 mm wide; nearly 0.33 mm tall; slightly arched just behind 
PME to beginning of steep posterior declivity; surface smooth with 
a moderately well developed coat of dark hair; with no evidence of 
any definite median fovea or groove. Eyes : six as usual in the genus 
(Fig. 6); posterior row occupies about five-fifths of width of cara- 
pace at that level and only a little wider than anterior row; viewed 
from above, definitely recurved. Ratio of eyes ALE : PME : 
PLE = 8.5 : 7.75 : 7.5. ALE separated from one another by 
nearly three-fourths of their long axis; separated from PME by 
somewhat less than one fourth of their long axis and from PLE
