PACIFIC SCIENCE, Vol. VII, October, 1953 
scribed species mentioned above has slender, 
relatively hairless palpi as in Stegomyia). Vertex 
dorsum with a variable area of narrow scales 
medially (confined to nape in wainwrighti and 
in some specimens of ostentatio; all narrow- 
scaled in V. nocturnus), remainder broad-scaled, 
Scutellum either broad- or narrow-scaled. Pa- 
ratergite with or without scales. No lower 
mesepimeral bristles. Fore and mid-tarsal 
claws of male unequal, each unidentate; hind 
claws equal, simple. Tarsal claws of female 
equal, fore and mid each unidentate; hind 
simple. Terminalia: Basistyle without true 
apical lobes and without basal lobe, except 
in V. nocturnus where a setose basal plaque 
occurs. Dististyle greatly swollen apically, ex- 
cept in V. nocturnus, the enlarged portion bear- 
ing a complicated arrangement of hairs and 
modified setae. Claspettes absent. Mesosome 
divided into two lateral plates, each of which 
bears several teeth laterally. 
LARVA: Separable from all the other sub- 
genera in the Philippines, except Ochlerotatus 
and some specimens of the Finlaya species 
leucopleurus and aureostriatus, by the possession 
of an acus on the anal plate. Antennal hair 
tuft with 5-13 branches. Head hair 4 with 
2-8 branches, 5 and 6 with 1-7. Comb with 
16-26 small scales in a patch, or with 8-10 
large teeth in an irregular, partially double 
row. Siphon with an attached acus; 12-21 pec- 
ten teeth, each with one or more large ventral 
denticles; distal teeth more widely spaced and 
without denticles. Anal plate incomplete; 
ventral brush of 12-16 tufts, all but basal 
1-4 borne on a prominent, laterally connected 
barred area. Habitat chiefly rain-filled tem- 
porary pools, but also occasionally such 
places as stream margins and permanent pools 
and ditches. 
DISTRIBUTION: Seven species are known 
from the Philippines. This subgenus is largely 
confined to the Ethiopian and Oriental re- 
gions. 
SYSTEMATICS: Edwards (1932: 166) divid- 
ed the subgenus into eight groups. Knight 
and Hurlbut (1949: 29) modified this classifi- 
cation by combining Group D with Group C. 
No sharp division occurs between Stegomyia 
and Aedimorphus , the two subgenera being 
apparently intimately connected through 
Group A {apkoannulatus-gtoup) of the Ethio- 
pian region and through Group B {nummatus- 
group) of the Oriental region (via Group E 
of Stegomyia). 
In the Philippine fauna, Group C is rep- 
resented by alboscutellatus, mindoroensis, pam- 
pangensis, and punctifemore. In that fauna it is 
separable from Group G, represented only by 
vexans nocturnus, in the absence of a basal lobe 
on the basistyle and in the possession of an 
apically swollen and markedly modified dis- 
tistyle. The positions of ostentatio and wain- 
wrighti are uncertain because the males are as 
yet undescribed. The other groups are not. 
represented in the Philippines.
