NO. 3657 SUBGENUS CULEX—BRAM 53 
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 long setae. Apical lobe 
of the basistyle prominent, divided into a large, proximal lobe and a 
small distal tubercle; also clothed with fine setae. Appendicles of the 
apical lobe as follows: three subequal, strong rods which are gently 
curved at the apex on the proximal lobe; an accessory seta may also 
be present; distal tubercle with three to five subequal, gently curved 
setae; 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, 
distinctly separated from the teeth of the median process, bent so as 
to be directed laterally; at the crest of the bend the margin seems to 
be somewhat rugulose. Median process with five to 10 strong, sharply 
pointed, subequal teeth. Basal process short, straight, and bluntly 
rounded. 
Larva: Similar to Culex coronator. Detailed descriptions of the 
immature stages are not available, and individual rearings of speci- 
mens belonging to this species were not examined. 
MATERIAL EXAMINED.—Ten male terminalia from areas indicated

Culex (Culex) covagarciai Bram [sic].—Forattini, 1965, p. 128. 
SysTemMatics.—Culex covagarciai is distinguished from other mem- 
bers of the complex by appendicles of the apical lobe of the basistyle 
and the ventral cornu. The apical lobe of the basistyle is extended 
into a thumblike projection. On this lobe is one short, very broad 
rod and two long, prominently hooked rods; there are also several 
subequal hooked setae next to the rods. The setae at the apex of the 
basistyle are not long. The ventral cornu, although similar in shape 
to that of other members of the complex, is considerably longer than 
in the other species. At the crown on the bend of the ventral cornu, 
the margin appears to be finely spiculate. 
SALIENT CHARACTERS.—Adult female: Unknown. 
Male terminalia: Basistyle conical, slightly longer than two and 
a half times the basal width; clothed with fine setae in addition to the 
normal, long setal pattern; setae at the apex very small and short.
