Aedes of the Philippines — Knight AND HULL 
one simple and the smaller claw with a single 
very small tooth which is overlooked unless a 
slide mount is made; hind tarsal claws equal, 
simple. Wings: Brown-scaled. Halter stem 
pale, knob darker and with dusky scales. 
Abdomen: Tergites dark-scaled, I and II with 
a band of white scales along the lateral mar- 
gin, III-VII with a basolateral patch of white 
scales. Sternites pale-scaled basally, brown- 
scaled apically. Terminalia (this description is 
adapted from Hoogstraal and Chamberlain, 
1946: 125. The abbreviations are those used 
in their figure): Basistyle densely clothed 
with scales and numerous long setae; a con- 
spicuous dense row of setae along the full 
length of the inner tergal margin. Basal lobe 
very large, divided into three sublobes as 
follows: a tergal sublobe (BLD) which is 
bulbous basally, constricted apically, and 
densely covered with fine hairs; a medial sub- 
lobe (BLM) with seven heavy flattened sub- 
equal filaments arising from separated elong- 
ate bases; and a stout sternal pedicel-like lobe 
(BLV) bearing two heavy flattened filaments. 
Basistyle apically with a knob-like tip, this 
extending beyond base of dististyle and 
bearing a cluster of striated pointed flattened 
filaments. Ninth tergite a narrow weakly 
sclerotized band, lacking lobes or setae. 
Female. Differs from male as follows: Pal- 
pus approximately one sixth as long as the 
proboscis. Tarsal claws equal, simple. 
LARVA: Head: Antenna smooth; antennal 
hair single, inserted at apical third and extend- 
ing slightly beyond tip of antenna. Mouth 
brush with comb-like tips. Hair 4 with 6-10 
branches; 5 single, lightly plumose, extend- 
ing beyond the anterior margin of the head; 
6 double (rarely triple) , shorter than 5 ; 7 with 
8-17, lightly plumose; 8 with 2-3; 9 with 3-6; 
12 with 6-9, large, finely plumose; 13 single; 
14 with 1-2; 15 with 2-3; 17 and 18 single; 
20 with about 6 fine branches; hairs 4 and 6 
well anterior to 7, 4 just within and posterior 
to 6, 5 lateral to 6. Mentum with 11-14 
lateral teeth. Thorax: Pro thoracic hair 1 with 
2-4 branches. Abdomen: Dorsolateral hair on 
159 
I with 4-9 branches; on II with 6-12. Lateral 
hair on I single; on II with 2-5, very short; on 
III-V with 3-4; on VI with 1-2. Pentad hair 
1 with 3-5 branches; 3 with 2-4; 5 with 1-2. 
Comb with many small yellow narrow scales 
in a triangular patch, each scale rounded and 
usually slightly enlarged apically and with a 
complete fringe. Siphon with about apical 
one fifth paler than remainder; acus absent; 
index about 3.1 (after Hoogstraal and Cham- 
berlain, 1946: 128); 11-17 pale, ventrally 
fringed pecten teeth, all approximately equal 
in length; siphon hair single, finely plumose, 
inserted just beyond middle and just beyond 
apical pecten tooth, extending slightly be- 
yond apex of siphon; dorsolateral and ven- 
trolateral basal valve hairs single (occasionally 
double), unusually long. Anal plate broadly 
incomplete; Ih with 1-2 branches, nearly 
twice as long as the anal plate; isc with 7-9, 
osc single; ventral brush of 10 tufts (once 9 
and once 11, however), each tuft with 4-8 
branches, all but basal 1-3 tufts borne on a 
barred area; barred area not connected 
laterally. Anal gills bulbous or finger-like, 
broadly rounded apically; dorsal pair 1.4-1. 8 
times longer than ventral pair and 1.7-2. 7 
times longer than the anal plate. 
BIONOMICS: The larvae were commonly 
collected in the axils and stumps of nipa 
palms in and along mangrove areas. Less 
commonly, they were found in tree holes, and 
once in a half coconut shell in a mangrove 
area. In the original description of fusca^ 
Leicester reported collecting the larvae from 
the axils of the atap palm. 
Adults were collected, always in or at the 
margins of mangrove areas, from around 
humans, from vegetation, and from the en- 
trances of crab holes.
