1946. Aedes {Finlay a) rizali Banks. Baisas, 
Phil. Bur. Health Mon. BuL 22: 21. Mis- 
identification. 
Adult and larva have been described by 
Barraud (1934: I9I) and Knight (1947^: 
628 ). 
DISTRIBUTION: Specimens examined. U.S.- 
N.M. Palawan: Puerto Princesa. Irahuan and 
Balsahan Rivers. 
Outside of the Philippines it is known from 
Malaya, Java, Siam, and India. 
DISCUSSION: There are four larval speci- 
mens from Palawan deposited in the U. S. 
National Museum as Finlaya sp. No. 42 that 
possibly represent a species near to saxicola. 
They have been described by Knight (1947^: 
647). The differences between these larvae 
and that of saxicola apparently consist en- 
tirely of the possession by the former of more 
heavily branched hairs. This difference, al- 
though striking in appearance, is a rather 
minor one. Consequently, they may represent 
only a polymorphic form of saxicola, rather 
than a new species. 
Aedes (Finlaya) abadsantosi Baisas 
1946. Aedes {Finlaya) abadsantosi Baisas, Phil. 
Bur. Health Mon. Bui. 22: 25 (male, fe- 
male, pupa, larva). Type locality: Philip- 
pines. Llavac, Infanta Municipality, Taya- 
bas Prov., Luzon (Baisas). Type: Male 
(holotype), with associated larval and pu- 
pal skins, in the Philippine Bureau of 
Health, Manila. Terminalia separated. 
Adult and larva also described in detail by 
Knight (1947^: 641). 
DISTRIBUTION: Specimens examined. U.S.- 
N.M. Samar: Osmena and Sohoton Springs, 
on Basey River. Mindanao: San Ramon, Zam- 
boanga Prov. A.N.S.P. Leyte: Lagolago, nr. 
Bay bay, Dagami. Samar: Osmena. 
Literature records. Luzon: Upper Molawin 
Creek, Los Banos Agr. Coll., Laguna Prov. 
Type series, Llavac, Infanta Municipality, 
Tayabas Prov. (Baisas, 1946: 25). 
Unknown outside the Philippines. 
DISCUSSION: This and the following three 
species {burgosi, rizali, and sherki) are all very 
closely related and probably represent either 
a polymorphic or a polytypic species. Quite 
likely, jugraensis can also be included within 
this complex. However, the available collec- 
tion data are too meager to solve this prob- 
lem. 
Aedes (Finlaya) burgosi Baisas 
Fig. 8 
1946. Aedes {Finlaya) burgosi Baisas, Phil. 
Bur. Health Mon. Bui. 22: 27 (males, fe- 
males, larvae, pupae). Type locality: Philip- 
pines. Titunod Creek in Kolambugan, 
Lanao, Mindanao (Guinto). Type: Male 
(holotype), non-existent. Paratypes in the 
Philippine Bureau of Science, Manila, and 
in the U.S.N.M. 
DISTRIBUTION: Known definitely only from 
the type series. 
DISCUSSION: From the discussion of this 
species by Knight (1947/^: 643), it would 
appear that burgosi probably represents only 
a polymorphic form of abadsantosi. The adults 
are not separable on external characters. The 
male terminalia differ only in that burgosi 
possesses 12-30 bristles on each lobe of the 
ninth tergite, whereas abadsantosi has 4-10 
bristles on each lobe. The larva of burgosi 
differs from abadsantosi on the greater number 
of branches of some of the hairs, and on the 
pecten not having any of the teeth distinctly 
out of line ventrally.
