Culex (Culex) deanei Correa and Ramalho, 1959, p. 141. [New synonymy]. 
Sysrmmatics.—Comparison of the paratype male terminalia of 
Culex deanei (SEMPDC 6.777) with the holotype male terminalia and 
a series of other specimens of C. chidesteri revealed that these two 
species are conspecific. Therefore, C. deanei is here designated a 
synonym of C. chidestert. 
QOulex chidesteri is similar to C. nigripalpus by possessing broad, 
spatulate spines on the lateral margins of the tenth sternite; it is 
similar to C. peus in that both possess a large, rounded, and rugulose 
ventral cornu; however, the broadly curved and laterally directed 
external process is distinctive. 
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 strong and hooked at the apex; median rod longer and 
broader than the basal rod and with a prominent terminal hook; 
apical rod about as broad as the basal rod, slightly longer than the 
median rod, and hooked terminally; leaf small, obovate, with minute 
longitudinal striations; two subequal accessory setae, one gently 
curved, the other prominently hooked. Dististyle normal. Tenth 
sternite crowned with a dense tuft of short, pointed spines apically 
and spatulate, scalelike spines on the lateral outer margins; basal 
arm moderate in length, slightly curved; two cercal setae present. 
External process broad and curved so as to be directed to a lateral 
point; not reaching the ventral cornu. Ventral cornu large, rounded, 
and rugulose. Median process with 15 or more short, pointed, 
conglomerate teeth. Basal process absent. 
Larva: Antennal tuft located in a constriction near the outer third; 
antennal shaft spiculate basally. Postclypeal head hair 4 short, 
single; upper frontal head hair 5 with six to eight branches; lower 
frontal head hair 6 long, triple; preantennal head hair 7 multiple. 
Mentum broad, with about 13 teeth; the apical tooth is generally
