Fig. 20. A . ( Stegomyia ) hoogstraali . Larval terminal 
segments (Culion). 
straali in the key given by Knight and Roze- 
boom (1946: 83) but not enough to differ- 
entiate the two. Until more material of this 
species is available from the Celebes, it will 
not be possible definitely to determine the 
status of hoogstraali. However, pending such 
an event the name hoogstraali is maintained 
for the Philippine material. 
This species may be distinguished easily 
from all the other members of the alholineatus 
group by the narrow-curved creamy-white 
scales on apn and ppn.
