Culex coronator differs from other members of the complex by the 
arrangement and number of appendicles on the apical lobe of the 
basistyle. In (. coronator there are two or three strong rods basally 
followed by five to 15 subequal setae. A patch of setae is present at 
the apex of the basistyle, but the setae are short. In C. usquatus, 
C. camposi, and CO. usquatissimus, the setae at the apex of the basistyle 
are very long and extend to at least the midpoint of the dististyle. 
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 the normal, long 
setal pattern; at the apex is a small patch of short setae. Apical 
lobe of the basistyle prominent, undivided, and also clothed with 
fine setae. Appendicles of the apical lobe as follows: two or three 
subequal, strong rods, which are gently curved at the apex; a group 
of five to 13 subequal, gently curved setae distad of the rods; leaf 
absent. Dististyle normal. Tenth sternite crowned with a sparse 
tuft of short, pointed spines; basal arm rather long, gently curved; 
three cercal setae present. External process gradually expanding 
distally to the midpoint, then tapering to a point; slightly exceeding 
the ventral cornu in length. Ventral cornu long and slender, dis- 
tinctly separated from the teeth of the median process, bent so as 
to be directed laterally; at the crown of the bend, the margin seems 
to be somewhat rugulose. Median process with five to 11 strong, 
sharply pointed, subequal teeth. Basal process short, 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 long, three 
or four branched, and barbed; preantennal head hair 7 long, multi- 
ple, and barbed. Mentum with about 15 teeth; the apical tooth is 
broader and longer than the lateral teeth. Thorax spiculate. Comb 
with many scales in a patch; each scale rounded apically and fringed 
with subequal spinules. Siphonal index 8.0 to 9.0; four double 
siphonal tufts inserted on the siphon beyond the pecten; a crown of 
prominent spines is present at the apex of the siphon. Pecten with 
eight to 14 teeth on the basal fourth of the siphon; each tooth with 
two to five coarse barbs on one side. Anal segment spiculate, 
completely ringed by the saddle.
