PACIFIC SCIENCE, Vol. IX, April, 1955 
Hair 8-VII not stellate, small, usually 3b. 
Hair 6-1-11(4, 3b, occasionally 2b), 6-III-VI 
(2b, 1), 7-1-11(3, 2b). Terminal abdominal seg- 
ments as in Figure 6. 
Discussion 
Apparently this species has been collected 
only once. I have seen three whole larvae and 
two pupal skins through the courtesy of Dr. 
Mattingly. Much more material is needed 
before the range of variation in the chaeto- 
taxy of this species can be determined but 
there is little doubt that rotumana is a member 
of the caledonica complex. It is interesting to 
note that rotumana is the most isolated mem- 
ber of this complex geographically and that 
it is the only one that has developed striking 
differential adult characters. On the other 
hand, in the immature stages it has not de- 
parted markedly from the general pattern in 
the complex, certainly not as much as cale- 
donica. There is no data as to the larval habitat. 
The short siphon and the poor development 
of the stellate hairs in the larvae of rotumana 
that I have examined suggest that these larvae 
were not tree hole breeders but this is con- 
tradicted by the small size of the anal gills 
and the branching of hairs 1 and 2 on the 
anal segment. The three larvae exhibit con- 
siderable variation in the development of the 
stellate tufts. Since these larvae were probably 
collected in a single breeding place, this varia- 
tion suggests that rotumana may also show 
environmental modifications in different hab- 
itats. 
Distribution 
Rotuma Island. Larvae collected Apr., 
1928 (Dr. W. D. Carew), reared in Suva, Fiji, 
by R. W. Paine [BMNH].
