PACIFIC SCIENCE, Vol. VII, October, 1953 
1946. Aedes {Aedes) nubicolus Laffoon, Jour. 
Wash. Acad. Sci. 36: 237 (2 males). 
Type locality: Philippines, Sibulan Riv- 
er, at 7,000-8,000 feet on Mount Apo, 
Cotabato Prov., Mindanao (Clagg). 
Type: Male (holotype) in Museum of 
Comparative Zoology, Cambridge, 
Mass. 
DISTRIBUTION: Literature records. Known 
only from the type series. 
DISCUSSION: This species, which is known 
only from the male, is apparently indistin- 
guishable externally from macrodixoa and un- 
cus. However, the male terminalia is distinct 
from that of all species known. 
Aedes (Aedes) uncus (Theobald) 
1901. Ctdex uncus LAstchAd., Mon. Cul. 2: 53 
(2 females). Type locality: Malaya. 
Klang, Selangor (Butler). Type: 2 fe- 
males (cotypes) in B.M.j Terminalia 
mounted. These two specimens are not 
conspecific. Therefore, at this time the 
name uncus is restricted to the specimen 
bearing the following penciled label: 
"Klang. Among plantains.” The other 
female, labeled "Klang jungle. IX. 99” 
in ink on the back of the card support- 
ing the pin, is an unnamed species. 
1908. Aioretomyia Varietas Leicester, Cul. Ma- 
laya, p. 185 (1 male, 2 females in type 
series). Type locality: Malaya. Kuala 
Lumpur (Leicester). Type: 1 male, 2 
females (cotypes) in B.M.f Both male 
and female terminalia mounted. The 
two females are conspecific with uncus 
(new synonymy). The male is a dis- 
tinct species, and at this time the name 
varietas is restricted to this male spec- 
imen. 
Adult described by Laffoon (1946: 237). 
DISTRIBUTION: Literature records. Culion. 
Palawan: Puerto Princesa. Irahuan River Val- 
ley. Balabac Island: Cape Melville. (Laffoon, 
1946: 238.) 
Known outside the Philippines only from 
Malaya. 
The Mt. Apo, Mindanao, record of Bohart 
(1945: 66) was based upon the type specimens 
of nubicolus. 
DISCUSSION: The two specimens (Edwards, 
1917: 223, stated that there was only a single 
type specimen) used by Theobald in describ- 
ing this species have been examined by the 
senior author and found not to be conspecific. 
As pointed out in the synoptic table above, 
the specimen bearing the label ' 'Klang. Among 
plantains.” has been selected as the type for 
uncus. The other specimen apparently rep- 
resents an undescribed species or at least one 
in which the female stage is unknown. 
The specimen selected as type has a rather 
poor terminalic mount, but it was possible 
to see all of the structures except the preatrial 
sclerite and the preatrial plate. In all details 
seen, the terminalia compared well with a 
female terminalia of what has been considered 
to be uncus in the Philippines by Laffoon 
(1946: 237). However, externally this type 
specimen differs slightly, as follows: only 7-9 
hairs on the anterior part of the sternopleuron, 
and about 20 fine hairs scattered all along the 
posterior margin of the sternopleuron. This 
difference in the number of hairs on the an- 
terior portion of the sternopleuron is suffi- 
cient to keep this specimen from keying to 
uncus in the key to the Philippine species of 
the subgenus Aedes prepared by Laffoon 
(1946: 229). 
The other female type specimen differs 
completely from uncus as treated here in lack- 
ing anterior sternopleural hairs altogether and 
in having only up to 4 hairs on the mese- 
pimeron below the dorsal hair tuft '(these 
occur posterior to the scale patch). The ter- 
minalia of this specimen resembles that of cam- 
pylostylus except that there are apparently no 
postatrial hairs. However, the slide is very 
faded, and it was only possible to say that 
it was not uncus as figured by Laffoon (1946, 
hg. 21). 
Edwards (1917: 223) arbitrarily associated 
two Malayan male specimens from Leicester’s 
collection with Theobald’s types of uncus. Ex-
