NO. 3557 SUBGENUS CULEX—BRAM 79 
and broadly flattened at the apex. Ventral cornu dentiform, similar 
in size and shape to the teeth of the median process. Median process 
with two series of teeth, the first consists of four very large teeth, 
the second consists of six or seven smaller, sharply pointed teeth. 
Basal process short, straight, and bluntly rounded. 
Larva: Unknown. 
MATERIAL EXAMINED.—None. Known to the author from the 
descriptions of Lane (1945 and 1953). 
DistrisuTion.—That of the type locality, Maues, Amazonas, 
Brazil.

SYSTEMATICS.—This species is similar to Culex brevispinosus, C. 
surimamensis, and C. oswaldoi. It differs in the appendicles on the 
apical lobe of the basistyle and in the conformation of the structures 
of the mesosome. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle tubular, about three times as long as 
the basal width; clothed with fine spicules in addition to the normal, 
long setal pattern. Apical lobe of the basistyle rather flattened, 
undivided, and also clothed with fine spicules. Appendicles of the 
apical lobe as follows: about six subequal, straight, fine setae present; 
rods and leaf absent. Dististyle normal. Tenth sternite crowned 
with a sparse tuft of short, pointed spines; basal arm very long and 
prominently curved; two cercal setae present. External process 
eradually tapering to a point; not 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 six 
short, robust, pointed teeth. Basal process short, straight, and 
bluntly rounded. 
Larva: Unknown. 
MatTERIAL EXAMINED.—Seven males and their associated terminalia 
from Brazil, and two from Argentina. The lectotype male terminalia 
from San Pedro, Argentina was also studied. 
Distripution.—Reported from the state of Tucuman, Argentina 
(the type locality), and the states of Bahia and Rio Grande do Norte, 
Brazil. The author has seen specimens in the U.S. National Museum 
collection from Recife, Pernambuco, Brazil, and Piedade, Sao Paulo, 
Brazil.
