stage, i.e., by the presence of a pecten on the 
siphon. However, the general habitus of the 
Armtgeres adult is relatively distinct, and the 
proboscis is generally stouter and more con- 
spicuously recurved. Other important char- 
acters of the genus Aedes are: Prescutellar 
bristles present (not in platylepidus) . Apn 
lobes widely separated. Postnotum without 
setae. Spiracular bristles absent. Upper margin 
of meron above level of base of hind coxa. 
Pulvilli absent, or hair-like. Squama with a 
fringe of bristles (more than four) . Wing with 
distinct microtrichia. Vein 6 reaching beyond 
base of fork of vein 5. 
LARVA: Not distinct from that of Heizman- 
nia, but distinguished from the other genera 
in the Philippines by the combination of the 
following characters: Siphon with a pecten 
and with only a single pair of ventral hair 
tufts, and ventral brush of eighth segment 
including at least four hairs. 
DISTRIBUTION: Worldwide. Of the 23 
recognized aedine subgenera, 12 are known 
to occur in the Philippines. The following 
subgenera have not yet been found there: 
Chaetocruiomyia, Diceromyia, Dunnms, Howard- 
tna, Indusius, Leptosomatomyia, Levua, Mac- 
leaya, Pseudoskusea, Kompia, and Soperia. 
Faunistically the Philippine Islands are a 
part of the Oriental Region. This is well illus- 
trated in the genus Aedes. Of the 74 known 
Philippine species, only 11 also occur in the 
Australasian Region, 2 in the Ethiopian 
Region, and 1 in the Palaearctic Region. 
Within the Oriental Region the Philippine 
Aedes fauna is an intimate part of the Malayan 
Subregion. However, as would be expected 
from the isolated position of the Philippines, 
the Aedes fauna there is particularly rich in 
endemic forms, 46 species at present being in 
this category. 
Subgenus Mucidus Theobald 
1901. Mucidus Theobald, Mon. Cul. 1: 268. 
Genotype: alternans^ (Australia). 
ADULT: Distinguished from all the other 
subgenera in the Philippines by either of the 
following: Wing membrane surrounding 
crossveins 2-3, 3-4, and 4-5 clouded, these 
three approximated; ppn with 10-30 bristles. 
Other characters: Palpi of male as long as or 
longer than proboscis. Vertex dorsum and 
scutellum narrow-scaled. Paratergite scaled. 
Lower mesepimeral bristles present. Fore and 
mid tarsal claws of male unequal, larger claw 
bidentate or unidentate, smaller unidentate; 
hind claws equal, simple or unidentate; of 
female equal, each unidentate. Terminalia: 
Basistyle with a weakly developed basal lobe, 
but without an apical lobe. Mesosome simple. 
Claspettes present. 
LARVA: Distinguished from all the other 
subgenera in the Philippines by any of the 
following: Mouth parts modified for pre- 
dacity, the mouth brushes forming matted 
tufts of serrate-tipped rods and the mandibu- 
lar teeth very large and strong; head hair 4 
considerably external to hairs 5 and 6; ventral 
brush extending the complete length of the 
anal segment. Habitat — temporary ground 
pools. 
DISTRIBUTION: The 13 known species and 
subspecies are confined to the tropics of the 
Ethiopian, Oriental, and Australasian Re- 
gions. Two species and one subspecies are 
known from the Philippines. 
SYSTEMATICS: The subgenus has been di- 
vided by Edwards (1932) into two groups: 
Group A {Mucidus') and Group B (Pardomyia) 
(see adult species key for separation points). 
Group A is represented in the Philippines by 
ferinus Knight and laniger (Wiedemann) and 
Group B by aurantius quadripunctis (Ludlow) .
