Aedes of the Philippines — Knight and Hull 
Fig. 12. a. {Finlay a) niveus. Larval head (Palawan). 
Drawn from exuvium. 
of Group H. The niveus subgroup, consisting 
at present of 12 valid species and subspecies, 
is distributed throughout the Oriental Re- 
gion. Although insufficient data are available 
at present, it appears to be at the super- 
species stage in development. 
Since the appearance of the treatment of 
the niveus subgroup by Knight (1946), the 
senior author has had the opportunity of 
seeing the lectotype of niveus and the male 
allotype of pseudonivea in the British Museum. 
The terminalia of the latter was separated and 
examined. Both specimens were found to be 
typical niveus as treated here. 
Knight (1946: 278) described the female 
scutum as having the anterior two-thirds 
solidly white-scaled. However, in a number 
of the specimens from Leyte and in one of 
the three females from Mindoro listed in the 
distribution section above, the white scutal 
patch is interrupted posteriorly for as much 
as three-fourths of its depth by a median 
extension of the posterior dark-scaled area. 
Apparently the female of this species is not 
definitely separable from that of lacteus. 
However, it is possible that the palpi are 
247 
shorter in ladeus (about one-eighth length of 
proboscis in few observed cases) than they 
are in niveus (one-fifth to one-sixth as long). 
Aedes (Finlaya) lacteus Knight 
1946. Aedes {Finlaya) lacteus Knight, Jour. 
Wash. Acad. Sci. 36: 275 (male, female, 
larvae). Type locality: Philippines. Cape 
Melville, Balabac Island (Laffoon and 
Johnson). Type: Male (holotype) in U. S. 
N. M.j Terminalia mounted. 
DISTRIBUTION: Known only from the type 
series of one male, one female, and two 
larvae. A female specimen in the U.S.N.M. 
from Parang, Mindanao (Paullus), is possibly 
this species, but in the absence of a male 
positive identification is not possible. 
DISCUSSION: This species possibly repre- 
sents only a polymorphic form of niveus^ 
being closely similar to it in the adult and 
larval stages. 
Externally, the male is not definitely 
separable from that of either niveus or 
laoagensis.

1946. Aedes [Finlaya) saperoi Knight, Jour. 
Wash. Acad. Sci. 36: 271 (males, females, 
larvae). Type locality: Philippines. Subic 
Bay, Luzon (Zedeck and Zolik). Type: 
Male (holotype), with associated larval and 
pupal skins, in U. S. N. M.f Terminalia 
mounted. 
DISTRIBUTION: Specimens examined. U.S.- 
N.M. Luzon: Subic Bay, Zambales Prov. 
Mindanao: 4 females, 3 sets assoc, skins, 
Pasanonco, Zamboanga (Laffoon). 3 males, 
3 females, Kisante, Kidapawan, Cotabato 
Prov. (Enke, Corcega). 
Unknown outside the Philippines. 
DISCUSSION: The Pasanonco specimens 
listed above were treated by Knight (1946: 
280) as an unidentified species. The later
