Culex iyengari n. sp. — MATTINGLY AND RAGEAU 
247 
Fig. 5. a, C. iyengari n. sp., larva, head and terminal segments; b, comb spine of C. pacificus. Mentum somewhat 
enlarged. 
tuft of about 20 rather short branches, inserted 
at about seven-tenths the distance from base 
to apex. Clypeal spines rather short, very 
slender, only slightly curved. Maxillary spine 
absent. Mentum with about 11-14 teeth on 
either side of the main central tooth. Head 
seta A about three-fifths the length of the 
head, B and C slightly longer, A with about 
6-12 branches, B with 3-5, C with 4 or 5, 
d single. Comb of about 25-45 uniformly 
fringed scales. Siphon with distinct sinusoidal 
flexure. Index (uncrushed) about five to five 
and a half. Spine at base of dorsal valves small, 
straight, simple, recurved at extreme tip. 
Pecten of about 10-14 teeth, each with 2-5 
coarse basal denticles (3 or 4 on the larger 
teeth) . Sub ventral tufts varying in length 
from about four-fifths to one and one-fifth the 
diameter of the siphon at point of attachment. 
Distal edge of saddle with only very minute 
spicules. Ventral brush with 12 tufts in the 
barred area. No precratal tufts. Saddle hair 
shorter than saddle, single or bifid. Upper 
caudal seta bifid or trifid, lower single. 
breeding PLACES: Barrels, tanks, native 
canoes, cistern, hole in coconut trunk, rock 
hole in coral, and a deep well with foul and 
muddy water. 3 From all other known Pacific 
dark-legged Culex of the typical subgenus the 
present species is markedly distinct in male 
terminalia. It is readily distinguished from all 
except C. pacificus on the character of the male 
palps. (C atriceps Edwards has these even more 
nearly bare and C. marquesensis Stone and 
Rosen (1953: 354) is intermediate between 
the present species and C. pipiens .) Separation 
of female adults and of larvae can be accom- 
plished by means of the following keys.
