Fig. 1. a. {Geoskusea) hahasi. Tergal aspect of male 
genitalia. 
much longer slender hairs on apex and for a 
variable distance basally. Ninth tergite lobes 
with 13-27 short stout peg-like spines and 1 
or 2 bristle-like setae each. 
FEMALE. Wing length approximately 3.0 
mm. Largely similar to the male. Palpus ap- 
proximately one-sixth to one-fifth as long as 
the proboscis. Tarsal claws equal, simple. 
Larva: 
Unknown. 
Types: 
Holotype. Male (918.11), genitalia not 
separated, U.S.N.M. No. 59350, Iwahig Penal 
Colony, Palawan Island, Philippines, June 18, 
1945 (J. L. Laffoon), collected as an adult 
from a crab hole at the edge of a mangrove 
swamp. Paratypes. Two males, 1 female, same 
data as for holotype; 11 males, 1 female, 
Pintanahon, Samar, April 13, 1945 (Laffoon); 
1 male, Osmena, Samar, April 24, 1945 (Laf- 
foon, Knight); 1 female, Zamboanga, Min- 
danao, September 12, 1945 (Laffoon, John- 
son, Knight), taken from a light trap; 1 male, 
Zamboanga, Mindanao (Knight, Laffoon), 
September 15, 1945; 1 male, near Mangarin 
Bay, San Jose, Mindoro (Ross). All of the 
paratypes except the female from Zamboanga 
were collected as adults from the openings of 
crab holes in mangrove areas. 
The holotype and a portion of the para- 
types are deposited in the U. S. National Mu- 
seum. The remainder of the paratypes are in 
the collections of the School of Hygiene and 
Public Health of the Johns Hopkins Uni- 
versity, the California Academy of Sciences, 
and of the authors. 
Discussion: 
Edwards (1932: 159) included fimhripes 
Edwards, longiforceps Edwards, and tonsus Ed- 
wards in the subgenus Geoskusea. In addition, 
he questioningly included daliensis (Taylor). 
Since that time, daggyi Stone and Bohart 
(1944:215) has also been added. In all of 
these species the male palpi are only about 
one-fourth as long as the proboscis. 
In attempting to place the new species de- 
scribed above, we found that both it and the 
closely related kabaenensis Brug (1939:108) 
(formerly placed in Skusea) from the Celebes 
are similar to the known Geoskusea species in 
all important details except that the male 
palpi are approximately two-thirds as long as 
the proboscis. Since no other basic differences 
could be found, Edwards’ (1932:159) defini- 
tion of Geoskusea is hereby enlarged sufficient- 
ly to include these two species. 
A. kabaenensis differs from baisasi 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 basistyle confined to the 
apex of the lobe. The proboscis is described 
as being one and one-half times as long as 
the fore femur. Also, neither Brug’s de- 
scription nor the senior author’s notes on the 
type of kabaenensis^ which is in the British 
Museum, mention the occurrence of fine 
hairs on the mesepimeron below the scale 
patch. Unfortunately, no specimens of bai-
