SysTeMATICcS.—Lane (1951) synonymized Culex archegus with C. 
articularis. Although, according to Stone et al. (1959) the type of 
C. articularis is nonexistent, Lane’s decision was not entirely arbitrary 
(Lane’s 1953 concept of C. articularis and C. archegus were synony- 
mous). Dyar (1928), however, considered C. articularis as a distinct 
species from C. articularis sensu Lane (—C. archegus). Lane (1953) 
did not even consider C. articularis sensu Dyar (1928). Since a 
neotype will be designated for C. articularis Philippi sensu Dyar, C. 
archegus Dyar is here revalidated. 
Culex archegus is a member of the salinariws complex due to the 
morphology of the male terminalia, but differs from C. salinarius, 
C. dolosus, C. spinosus, and C. alani, by possessing a clavate ventral 
cornu. Other characters of the mesosome are also distinctive. 
SALIENT CHARACTERS.—Adult female: See table 1. 
Male terminalia: Basistyle conical, slightly more than twice as long 
as 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, pointed, and curved at the apical tip; 
median rod somewhat more robust, prominently curved apically, and 
slightly longer than basal rod; apical rod more slender than median 
rod, prominently curved apically, and slightly longer than median 
rod; leaf obovate, moderate in size; accessory setae two, one short and 
hooked, the other long and gently curved. Dististyle normal. Tenth 
sternite crowned with a dense tuft of short, pointed spines; basal arm 
long and moderately curved; three or four cercal setae present. Ex- 
ternal process gradually tapering to a pointed tip, exceeding the ven- 
tral cornu in length. Ventral cornu dentiform, slightly separated 
from the teeth of the median process. Median process possessing 
about six subequal, sharply pointed teeth. Basal process rather 
stout, acutely bent posteriorly, pointed, and reaching to approximately 
the middle of the teeth of the median process. 
Larva: After Levi-Castillo (1953). Antennal tuft located in a 
constriction near the outer third; spiculate basally. Head hairs 5, 6,
