pointed spines; basal arm moderate in length, strongly curved; two 
cercal setae present. External process very broad medially, gradually 
tapering to a point; just reaching the ventral cornu in length. Ventral 
cornu large, round, and rugulose. Median process with four to eight 
distinct, pointed teeth. Basal process rather broad, straight, and 
bluntly rounded. 
Larva: Antennal tuft located in a constriction near the outer third; 
antennal shaft spiculate basally. Postclypeal head hair 4 short, 
single; upper and lower frontal head hairs 5 and 6 four to seven 
branched, barbed; preantennal head hair 7 multiple. Mentum with 
about 15 teeth; the apical tooth broader and longer than the lateral 
teeth; the subbasal teeth longer than the other lateral teeth. Thorax 
glabrous. Comb with numerous scales in a patch; each scale rounded 
apically and fringed with subequal spinules. Siphonal index 4.0 to 
5.0; with five pairs of siphonal tufts, the subapical pair out of line and 
double. Pecten with nine to 15 teeth on the basal third of the siphon; 
each tooth with one to five coarse barbs on one side. Anal segment 
completely ringed by the saddle. 
MATERIAL EXAMINED.—Thirty-nine males and associated terminalia 
from the United States, Mexico, and Costa Rica. 
DistTRIBUTION.—Reported from the western United States, Mexico,

SystemMAtTics.—The male terminalia indicates that this is a rather 
generalized species, but characters of the apical lobe of the basistyle 
and the mesosome distinguish it from other members of the subgenus. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle tubular, slightly longer than three 
times the basal width; clothed with fine setae in addition to the normal, 
long setal pattern. Apical lobe of the basistyle prominent, undivided, 
and also clothed with fine setae. Appendicles of the apical lobe as 
follows: basal rod strong, straight, and blunt; median rod longer 
and broader than basal rod, and prominently hooked; apical rod 
longer than, but not as broad as the median rod, also prominently 
hooked terminally; leaf moderate in size, obovate; two accessory 
setae present, one distinctly hooked terminally, the other as long 
as the leaf, gently curved, and pointed. Dististyle normal. Tenth 
sternite crowned with a dense tuft of short, pointed spines; basal 
arm moderate in length, gently curved; two to four cercal setae 
present in a compact group. External process gradually tapering
