distinctly recurved at the tip. Dististyle normal. Tenth sternite 
crowned with a dense tuft of short, pointed spines; basal arm moderate 
in length, gently curved; three cercal setae present. External process 
gradually tapering to a point. Ventral cornu and teeth of the median 
process absent (in the everted position a slight indication of the 
ventral cornu may be present). Basal process short, straight, and 
somewhat pointed at the distal end.

SysteMATIcs.—Two male terminalia slides determined by Cova 
Garcia as Oulex tejerat were compared with the holotype male ter- 
minalia of C. levicastilloi and found to be conspecific. Therefore, C. 
tejerai is here placed in synonymy with C. levicastilloi. 
Culex levicastilloi is readily distinguished from all other members 
of the subgenus by the characteristic appendicles on the apical lobe 
of the basistyle. 
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. 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 slightly curved at the apex; 
median rod longer and broader than basal rod, gently hooked ter- 
minally; apical rod longer than median rod, with a prominent ter- 
minal hook; two strong, short, serrate, plumose setae; a strong, 
hooked seta and a long, narrow, gently curved seta; leaf moderate 
in size, obovate. Dististyle normal. Tenth sternite crowned with a 
dense tuft of short, pointed spines; basal arm short and straight; 
about four cercal setae present. External process gradually tapering 
to a point, reaching the ventral cornu in length. Ventral cornu 
dentiform, very similar in size and shape to the teeth of the median 
process. Median process with about four distinct teeth. Basal 
process short, straight, pointed, and directed posteriorly. 
Larva: The larval stage was described by Cova Garcia (1962) as 
Culex tejerai. Antennal tuft located in a constriction near the outer 
third. Postclypeal head hair 4 short, single; upper and lower frontal 
head hairs 5 and 6 long, four branched; preantennal head hair 7 long, 
multiple. Mentum with about 13 teeth; the apical tooth larger than
