NO. 3557 SUBGENUS CULEX—BRAM 91 
distribution of appendicles on the apical lobe of the basistyle, by the 
short basal arm of the tenth sternite, and by the reduced mesosome. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, about two and a half times as 
long as 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 bluntly rounded; 
median rod slightly longer than basal rod and gently hooked terminally; 
apical rod not as broad as median and basal rods, gently hooked ter- 
minally; three accessory setae present, the one next to the apical rod 
is bicleft (one extension being pointed, the other hooked), next to the 
bicleft seta is a very strong, hooked seta, followed by the leaf; the 
third accessory seta as long as the leaf and gently curved; leaf moderate 
in size, obovate, and with distinct longitudinal striations. Dististyle 
normal. Tenth sternite crowned with a dense tuft of short, pointed 
spines; basal arm short, straight, and bluntly rounded; three to five 
cercal setae present. External process straight, somewhat tapered 
to a bluntly pointed tip; slightly exceeding the ventral cornu in length. 
Ventral cornu very broad and curved so as to be directed laterally; 
tapering to a terminal point. Median process without teeth. Basal 
process reduced to a short, rounded knob. 
Larva: Antennal tuft located in a constriction near the outer third; 
antennal shaft spiculate basally. Postclypeal head hair 4 short, 
single; frontal head hairs 5, 6, and 7 long, multiple, barbed. Mentum 
with about 23 sharply pointed teeth; the apical tooth longer and 
broader than the lateral teeth. Body glabrous. Comb with many 
scales in a patch; each scale rounded apically and fringed with sub- 
equal spinules. Siphonal index about 4.0; four siphonal tufts inserted 
on the siphon beyond the pecten. Pecten with six to 13 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.—Over 300 male terminalia from throughout 
the New World. 
DistriputTion.—This complex is cosmopolitan.

SysTEMATICS.—Senevet and Abonnenc (1946) described this species 
from larvae and adult females collected in French Guiana. Without 
suggesting reasons, Lane (1951) placed Culex pseudojanthinosoma in 
synonymy with ©. corniger. Subsequently Senevet and Abonnenc 
(1958) revalidated the species, described the pupa, and provided a
