Brady — Oxyopes 
233 
Diagnosis. Oxyopes scalaris is unlike any other Mexican or Cen- 
tral American species of Oxyopes , although it clearly falls within 
the limits of the genus. The closest relatives of O. scalaris appear 
to be certain European species, such as O. ramosus or O. heteroph-, 
thalamus (Brady, 1964). 
Oxyopes scaldris can be easily recognized by the epigynum (figs'. 
97-99 of Brady, 1964) and the male palpus (figs. 106, 107 of 
Brady, 1964).

Discussion. In 1963 I examined large numbers of O. salticus 
from North America southward to Brazil. I noted a slight differ- 
ence in the structure of the male palpus in specimens from central 
Mexico southward (Brady, 1964). Because of this difference (com- 
pare figs. 102, 103 to figs. 104, 105 of Brady, 1964) I decided to 
retain the name O. gracilis Keyserling for populations from central 
Mexico to Brazil. Having collected O. salticus in Mexico and 
Central America and examined numerous specimens from that area 
and South America, I have concluded that the slight differences in 
the male palpi between O. salticus and O. gracilis are simply a
