Holotype. Female from 15 mi. S of Florence, Pinal Co., Arizona, 
12 July 1968 (L. D. Mikelson) in the Museum of Comparative 
Zoology. The specific name is a noun in apposition after the Greek 
goddess Artemis. 
Discussion. One of the distinguishing characteristics of members 
of the apollo species group is the robust fourth legs. In other species 
of Oxyopes leg I is the longest and most powerfully developed. In 
those species with leg I longest the patella-tibia of a given leg is 
longer than any of the other leg segments and is a good indicator of 
relative leg length. In members of the apollo group, even though 
the patella-tibia of leg I may exceed the patella-tibia of leg IV 
in length, femur IV and metatarsus IV equal or exceed patella-tibia 
IV in length and leg IV is much the longest. For an adequate 
comparison of members of this group, therefore, the measurements 
of segments of leg I and leg IV are given below. The robust 
development of leg IV in species of the apollo group is undoubtedly 
related to their jumping ability and may be associated with their 
ecology, for example, their occurrence in rather barren areas in some 
cases. 
Measurements. Length of three females 5. 2-5. 6 mm, carapace 
width 1.8 mm, carapace length 2. 3-2.4 mm. 
Width of eye rows: AME .2 5-. 36 mm, ALE .5 4-. 5 8 mm, PLE 
1.03-1.08 mm, PME .54-. 56 mm. 
Segments of legs I and IV: femur 2.0-2. 1 mm, 2. 7-2. 8 mm, 
patella-tibia 2. 3-2.4 mm, 2. 5-2.6 mm, metatarsus 2.1 mm, 3. 1-3.2 mm, 
tarsus .8-. 9 mm, .8-.9 mm, total length 7.2-7. 5 mm, 9.2-9. 5 mm. 
Length of patella-tibiae: II 2.2-2. 3 mm, III 1 .6-1.7 mm. 
Color. Female. Pattern illustrated in Figures 7 and 8. Face and 
chelicerae pale orange-yellow to cream. White spatulate shaped, ap- 
pressed hair covering much of face and base of chelicerae. These 
white hairs thickest between ALE to AME, covering most of hexa- 
gonal region bounded by eyes in unrubbed specimens. An inverted 
T-shaped mark running from the AME to the lower edge of the 
clypeus is also formed by a dense alignment of these white hairs. 
Carapace pale orange-yellow to cream with light brown sub-
