PACIFIC SCIENCE, Vol. VI, April, 1952 
pie, tapered apically to a sharp point, outer 
portion more heavily sclerotized. Claspettes 
absent. 
LARVA: Separable from all the other aedine 
subgenera in the Philippines by the combina- 
tion of the following: Antennal hair short, 
single, inserted at about the apical two thirds. 
Head hair 6 directly anterior to 5, 4 mesad of 
6, 7 on a level between 5 and 6, all of them 
inserted far forward. Comb scales numerous, 
in a patch. Siphon without an acus; tuft 
single, hardly beyond middle; pecten teeth 
evenly arranged. Anal plate bare. Ventral 
brush consisting of 9-11 tufts, all but basal 
1-3 tufts borne on a laterally unconnected 
barred area. Habitat — chiefly in axils and 
stumps of nipa palms in mangrove areas, but 
also in other types of container habitats in 
mangroves. 
DISTRIBUTION: Five species are known at 
present, two of which occur in the Philip- 
pines. The others are pembaensis Theobald 
from Africa, dasyorrhus King and Hoogstraal 
from New Guinea, and lamelli ferns Bohart and 
Ingram from the Caroline Islands. A. kabaensis 
Brug has been removed by us to the subgenus 
Geoskusea, 
SYSTEM ATics: The four Pacific species are 
remarkably uniform in the general details of 
the adult and the larva. However, the African 
form differs markedly in the character of the 
mesosome, having it in the form of a simple 
tube. Also, the last two palpal segments are 
slightly thickened and hairy, and the female 
has lower mesepimeral bristles.

ADULT: A very small dark brown species, 
with all broad dark vertex and scutellar scales 
and with small laterobasal pale spots on the 
abdominal tergites. 
Male. Wing length 2. 0-2. 5 mm. Head: 
Proboscis all dark-scaled; slightly longer than 
the fore femur. Palpus approximately equal to 
the proboscis (exclusive of labellum) in 
length, measured range 0.75-1.0 times as 
long; dark; a very few short hairs at the apices 
of the distal three segments. Vertex covered 
with broad scales, these dark except for a 
transverse subdorsal white band which may 
be interrupted; a line of dark upright-forked 
scales along the nape, occasionally one or 
more along the anterodorsal margin also. 
Thorax: Scutal integument grayish brown; 
clothed with narrow brown scales. Scutellum 
with a prominent dense overlapping patch of 
broad dark scales on each lobe. Apn with a 
few broad dusky scales, ppn dorsally with 
broadened dark scales. Following pleural 
areas each with a patch of broad silvery-white 
scales: propleural, dorsal sternopleural, medio- 
posterior sternopleural, and mesepimeral 
(below the hair tuft); pleural sclerites rather 
uniformly grayish brown. Legs: Dark-scaled. 
Fore and mid-tarsal claws unequal, the larger
