Brady — Oxyopes 
195 
The remaining three species of Oxyopes found in Mexico and 
Central America are O. scalaris, O. salticus , and O. flavus. They 
are different from all other species found in this region. In context 
with the other species they would constitute distinct monotypic spe- 
cies groups. 
Oxyopes scalaris is essentially a temperate species whose southern 
limit of range extends into the northern Mexican plateau (Map 4). 
Oxyopes salticus is found in the United States and occurs throughout 
Mexico and Central America (Map 3). Oxyopes flavus does not 
occur north of Mexico (Map 4). 
UNIDENTIFIABLE SPECIES 
Nathan Banks (1898) described O. acutus based upon several 
young males from La Chaparos, Sierra Laguna, and Hermosillo, 
Mexico and an adult female from Baja California. The female 
which is figured by Banks, is O. scalaris Hentz. One of the imma- 
ture males is labelled as a type in the collection of the Museum of 
Comparative Zoology. The color pattern of this specimen matches 
that of several species in the O. tridens complex. Oxyopes acutus 
has appeared only as ian entry in faunal lists in the zoological litera- 
ture. The name has not been associated with any specimens since 
the original description by Banks. For that reason and because of 
the difficulty in accurately determining the species that the immature 
type represents, I think it best to consider O. acutus as a nomen 
dubium. 
The type female of O. actophilus described by Chamberlin (1924) 
has apparently been lost. The description, based upon an immature 
female type, is not adequate enough to determine the species with 
any accuracy. Therefore, I think that O. actophilus is also best 
considered a nomen dubium.
