Psyche 
[September 
Abdomen: ovoid; quite typical of males of the genus. Color in 
alcohol : carapace, sternum, legs and mouth parts all light yellowish ; 
abdomen nearly white with a faint reticulation. 
Female paratype. Total length 1.87 mm. Carapace 0.77 mm 
long; 0.64 mm wide opposite second coxae; 0.35 mm tall; rises 
gently from PME to beginning of posterior declivity opposite in- 
terval between second and third coxae and then descends to posterior 
border with a slight concavity just below the middle (Fig. 18). 
Eyes essentially as in male. Chelicerae, maxillae, lip and sternum : 
all seem to be essentially as observed in male holotype except that 
the sternum appears to be slightly grooved and lobed opposite the 
coxae ; third coxae nearly globose, others somewhat elongated ; clus- 
ters of short bristles occur on weakly developed lobes. Legs: 4213 
in order of length; first tibiae with three pairs of ventral spines; 
first metatarsi with two pairs of ventral spines; second tibiae and 
metatarsi with two pairs of ventral spines; third and fourth legs 
also with several spines on tibiae and metatarsi. Abdomen : in gen- 
eral essentially as in male; the epigynal area appears to be obscurely 
distinctive (Fig. 20) ; there is some chitinization in the region of 
epigastric scutum. Color in alcohol : essentially as in male except 
that the carapace, legs, sternum and mouth parts are somewhat 
paler; the faint reticulation shows about as in male. 
Diagnosis . The species appears to be most closely related to 
Oonops anoxus sp. nov. from Panama Canal Zone (in press). The 
features of the male palp together with the eyes and shape of the 
carapace seem to establish it definitely as a new species. 
Records. The described female paratype was taken with the holo- 
type along with numerous other specimens sifted from hay and weed 
debris. The species is abundant on St. Thomas, V. I. and I have 
many specimens from localities on this island collected during Feb- 
ruary, 1964 and August, 1966. I also have it from St. John, V. I., 
March, 1964, July, 1966 and March 27, 1970 (H. and F. Levi) ; 
St. Croix, V. I., March, 1964; Tortola, B. V. I., July 30-Aug. 5, 
1966. The species will probably be reported from islands further 
west in the third paper on this genus. 
Note. There are grounds for believing that the male described 
by Dr. Petrunkevitch as the male of Heteroonops spinimanus (Simon) 
is in reality a member of Oonops castellus sp. nov. The very poor 
condition of the specimens from the American Museum of Natural 
History, used by Dr. Petrunkevitch in his study of Puerto Rican 
spiders, precludes a definite decision regarding this matter.
