the basistyle. Two other species, C. foliaceus and C. lahillei, also 
possess two leaves on the apical lobe, but neither exhibits annulations 
on the apical third of the dististyle as does C. diplophyllum. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, slightly longer than twice the 
basal width; clothed with fine setae in addition to normal, long setal 
pattern. Apical lobe of the basistyle prominent, undivided, and 
clothed with fine setae. Appendicles of the apical lobe as follows: 
basal rod straight and pointed; median and apical rods longer than 
the basal rod and gently hooked; one fine, prominently hooked, 
accessory seta present; two leaves present, the proximal leaf large, 
obovate, and possessing distinct basal, longitudinal striations, the 
distal leaf very narrow but as long as the proximal leaf and also 
exhibiting longitudinal striations. Dististyle quite broad, possessing 
annulations on the apical third. Tenth sternite crowned with a 
dense tuft of short, pointed spines; basal arm moderate in length 
and sharply bent; three to four cercal setae present. External 
process gradually tapering to a point, exceeding the ventral cornu in 
length. Ventral cornu dentiform, close to the teeth of the median 
process. Median process with five to nine distinctly separated teeth. 
Basal process longer than the teeth of the median process, straight, 
and truncate. 
Larva: Antennal tuft located in a constriction near the outer third. 
Frontal head hairs 4, 5, 6, and 7 multiple. Mentum with about 20 
teeth; the apical tooth broader and longer than the lateral teeth. 
Body glabrous. Comb with many free scales in three or four rows. 
Siphonal index greater than 4.0. Pecten restricted to the basal third 
of the siphon followed by four multiple tufts and a single seta before 
the apex. Anal segment completely ringed by the saddle which is 
spiculose on the posterior margin. 
MATERIAL EXAMINED.—The lectotype male and a paratype male 
and associated terminalia from Lima, Peru, and another male specimen 
also from Lima, Peru.

Systematics.—Culex dolosus is a member of the salinarius complex. 
It differs from CQ. salinarius in the conformation of the basal process 
and the external process; it differs from C. spinosus in the length and
