Aedes of the Philippines — Knight AND Hull 
in a patch. Siphon with an acus; hair tuft 
branched and beyond middle; pecten teeth 
evenly arranged. Ventral brush of 12 tufts. 
Habitat— crab holes. 
DISTRIBUTION: The seven known species 
are confined to the Australasian and Oriental 
Regions. Only two species are recorded from 
the Oriental Region, one from the Celebes 
and one from the Philippines. 
SYSTEMATICS: The systematics of this sub- 
genus have been discussed by Knight and 
Hull (1951). They list the following species 
as belonging here: fimbripes Edwards, longi- 
forceps Edwards, tonsus Edwards, ? daliensis 
(Taylor), daggyi Stone and Bohart, kabaenensis 
Brug (formerly placed in Skusea), and baisasi 
Knight and Hull. 
Aedes (Geoskusea) baisasi Knight and 
Hull 
1951. Aedes {Geoskusea) baisasi Knight and 
Hull, Pacific Sci. 5: 197 (males, females). 
Type locality: Philippines. Iwahig Penal 
Colony, Palawan Island (Laffoon). Type: 
Male (holotype) in U.S.N.M.f Terminalia 
not separated. 
DISTRIBUTION : Specimens examined. Palawan : 
Iwahig Penal Colony. Mindanao: Zambo- 
anga, City of Zamboanga Prov. Mindoro: 
nr. Mangarin Bay, San Jose. Samar: Pintana- 
hon and Osmena. 
DISCUSSION: A. kabaenensis Brug from the 
Celebes is closely related to baisasi, differing 
from it mainly in possessing only 1-3 thick 
setae and 1-2 bristles on each lobe of the 
ninth tergite, and in having the slender 
elongate hairs of the basal lobe of the basi- 
style confined to the apex of the lobe. It 
seems likely that when more material is 
available, kabaenensis and baisasi will prove to 
be members (subspecies) of a single poly- 
typic species. 
A. baisasi and kabaenensis differ markedly 
from the other known Geoskusea species in 
having the male palpi approximately two 
thirds as long as the proboscis. Also, con- 
163 
spicuous differences occur in the male geni- 
talia. 
The larva is unknown. 
Subgenus Rhinoskusea Edwards 
1929. Rhinoskusea Edwards, Bui. Ent. Res. 
20: 342. Genotype: longirostris Leicester 
(Malaya) . 
ADULT: A small dark unornamented species. 
Differs from all the other Aedes species in the 
Philippines in having the first hind tarsal 
segment as long as, or longer than, the tibia. 
Palpi in both sexes very short. Scales of ver- 
tex and scutellum all broad and flat. Dorso- 
central and acrostichal bristles present. Para- 
tergite not scaled. No lower mesepimeral 
bristles. Male with tarsal claws slightly un- 
equal on all legs, the larger bearing a small 
basal tooth; female claws equal and simple on 
all legs. Terminalia: Basistyle with basal and 
apical lobes. Dististyle appendage apical. 
Mesosome simple. Claspettes absent. 
LARVA: Antennal hair tuft with 4-7 
branches. Comb with 50-75 scales arranged 
in a patch. Siphon with an attached acus, 
pecten evenly arranged, hair tuft inserted 
near apex. Anal plate incomplete. Ventral 
brush with 10 tufts, all but basal one borne 
on a barred area, this area not connected 
laterally. Habitat— crab holes and brackish 
ground pools. 
DISTRIBUTION: The one known species 
occurs in both the Australasian and Oriental 
Regions.
