is practically impossible; similar difficulties are encountered in respect 
to the epigynal areas of females and frequently these cannot be 
clearly represented in figures; small, subsurface, dark colored struc- 
tures usually show more or less clearly just anterior to the bases of 
the spinnerets much as in Stenoonops.

Oonops reticulatus Petrunkevitch, 1925: 98. The female holotype was from 
Panama City, Panama, but is now unavailable for study. Roewer, 1942:

No figures accompanied the original description and the female 
holotype was sectioned for the study of internal anatomy and, of 
course, was unavailable for examination in 1951 when I had but 
one male in my collection. Figure 1 shows the carapace of the male 
in profile and Figure 2 shows the eyes of the female; these specimens 
are from Corozal and Balboa, Panama Canal Zone, respectively. In 
both original descriptions cited above it was stated that true spines 
were lacking on the legs. Repeated examinations have now con- 
vinced me that there are actually true spines on the appendages 
although they are difficult to distinguish from numerous spiniform 
bristles and hairs. The ventral scuta in females are faintly outlined 
but the epigynal area is so indefinite and, apparently, variable in 
appearance that it seems impossible to provide reliable drawings of 
this region. The color pattern is highly variable among the specimens 
now assigned to this species; reticulation is very clear in some speci- 
mens but obscure in others; in some individuals the purplish color 
is subdivided into a series of irregular spots separated by yellowish 
areas. 
Records. Two males are now in the collection from Corozal, 
Panama Canal Zone, January 4, 1958; a third male was collected 
in the vicinity of Turrialba, Costa Rica, Aug. 10, 1965. More than 
a dozen females from several localities in the Panama Canal Zone 
were taken in 1950, 1954, 1958, i960 (W. J. Brown) and 1964; 
and also in Turrialba, Costa Rica., July-August, 1965. Two females 
from El Volcan, Panama, August, 1950 belong in this genus but 
their specific status is uncertain at present. It seems probable how- 
ever, that they will eventually be regarded as representing a new 
species.
