Certain segments of the male palpus may be covered dorsally with 
reflective white setae (characters 11, 11a, Fig. 1; Figs. 16- 18). These 
setae probably serve as a visual cue to the female during male 
courtship, and their presence is believed to be apomorphic. In 
saxatilis, only the patella bears such a covering; in atlantica, both 
patella and tibia are covered, and in parvula, both segments plus the 
basal half of the cymbium are covered. Males of only the remotely 
related P. tesquorum (Odenwall) have a similar covering on the 
palpal patella. We infer that the presence of this covering in the 
milvina group is apomorphic, and that the plesiomorphic state of 
the character is the involvement of a single segment. 
Unidentified Species 
A name associated in the past with the milvina group, namely, 
Lycosa canadensis Blackwall, 1871, treated as a junior synonym 
of P. milvina by Chamberlin (1908), could not be identified by 
us, and is treated here as nomen dubium. The holotype of cana- 
densis was an unidentifiable juvenile and is no longer in exist- 
ence. Pardosa accurata Becker, 1886, described from “Mexico”, 
has been identified as an unknown species of Lycosa, s.l, through 
examination of the holotype by us; the type is a juvenile speci- 
men deposited in the Institut Royal des Sciences Naturelles de 
Belgique. 
Description 
Total length 3.00 to 7.50 mm. Carapace smoothly convex at sides, 
vertical anteriorly at sides, approximately uniform in height 
between dorsal groove and posterior row of eyes, covered sparsely 
with short setae; eye area black, often iridescent; anterior row of 
eyes somewhat procurved, distinctly shorter than middle row, with 
median eyes equal in size to lateral eyes or somewhat larger and lo- 
cated slightly closer to laterals than to each other. Legs moderately 
long and strong, with thin scopulae and sparse setae; femur I with 3 
dorsal macrosetae, 2 prolaterals (near tip), 2 or 3 retrolaterals; tibia 
1 with 2 slender bristlelike dorsals, 2 prolaterals, 2 retrolaterals, 3 
pairs of ventrals; basitarsus I with 1 bristlelike dorsal, 3 prolaterals, 
2 or 3 retrolaterals, 3 paired and 1 unpaired ventral; trochanters 
with deep notch distally at tip. Abdomen ovoid, covered with dense, 
short setae and with cluster of longer, erect setae at anterior end.
