Culex (Culex) articularis Philippi, 1865, p. 596. 
Systematics.—Philippi (1865) described Culex articularis from 
Chile. Subsequently Dyar (1928) figured the distinctive male termi- 
nalia of this species. Lane (1951) synonymized C. archgeus with C. 
articularis and in his monograph (1953) included figures of the male 
terminalia of what he considered to be C. articularis. The terminalia 
of C. articularis sensu Lane, however, do not agree with the terminalia 
of C. articularis sensu Dyar, but are obviously those of C. archegus. 
Lane, in fact, did not even consider C. articularis sensu Dyar in his 
monograph under any name. Since no type specimen of Culex (Culez) 
articularis Philippi, 1865 exists (Stone et al., 1959), a neotype is hereby 
designated in accordance with article 75 of the International Code of 
Zoological Nomenclature (1961) in order to stabilize the nomenclator- 
ial status of this species. 
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 rather flattened, undivided and 
also clothed with fine setae. Appendicles of the apical lobe as follows: 
a dense basal patch of slender setae; basal rod strong, blunt, very 
slightly curved; median rod stout, curved, and slightly longer than 
basal rod; apical rod stout, curved, and slightly longer than the median 
rod; a broad, unusually hooked, rodlike projection; leaf narrow, curved, 
and pointed apically with minute striations; accessory setae three or 
four in number, one strong, as long as leaf and gently curved, and two 
or three short, straight, slender setae. Dististyle normal in size but 
minutely annulate at the distal third. Tenth sternite crowned with 
a dense tuft of short, pointed spines; basal arm robust and strongly 
recurved; possessing three to four cercal setae. External process 
gradually tapering to a point, slightly exceeding the ventral cornu in 
length. Ventral cornu dentiform, slightly larger than, and close to 
the teeth of the median process. Median process with about five 
distinct teeth. Basal process stout, pointed, and sharply bent so as 
to be directed posteriorly; some specimens have been observed, how- 
ever, in which the basal process is straight and pointed. 
Larva: Unknown. 
Nerotyrr.—A male and associated slide mounted terminalia de- 
posited in the U.S. National Museum with the following data: Casa 
Pangue, Llanquihue, Chile; December 1926; R. and E. Shannon; 
USNM RBé62 554.
