Spiders from Some Pacific Islands, II 1 
B. J. Marples 2 
I am indebted to Dr. N. L. H. Krauss for 
the collection of spiders which is described 
here. The specimens, with the exception of a 
paratype of the male of Leucauge ilatele re- 
tained in my own collection, will be depos- 
ited in the Bernice P. Bishop Museum in 
Honolulu. The collection contains examples 
of some 40 species from Tahiti, Raiatea, 
Moorea, and Borabora in the Society Group; 
from Aitutaki in the Cook Islands; from 
Upolu and Savaii in Western Samoa; from 
Tongatabu and from several localities in Viti 
Levu in the Fiji Islands. Experience with other 
collections from the islands has shown that 
species which are common on one occasion 
may be rare or absent on another, and so it 
has seemed advisable to list the numbers of 
individuals collected from each locality, 
whether the species has been recorded pre- 
viously or not. There are many new records, 
inasmuch as little or no collecting has been 
done in some islands. In some families iden- 
tification can only be tentative until a thor- 
ough revision has been carried out. It has 
been felt in some cases that it is zoogeo- 
graphically less confusing to erect new species 
or genera for island spiders, than to force 
them into, for example, continental Australian 
genera which are inadequately characterised.

Attention is drawn to such doubtful cases in 
the text, and this should be borne in mind 
in any consideration of faunae. A great deal 
of work is still needed before we have an 
adequate picture of the spider fauna of the 
Pacific islands, and still more of its relation 
to those of adjacent land masses. Berland 
(1934^ and b) has described the spiders of 
Tahiti and has also listed those known from 
Polynesia, together with their distribution. 
The spiders of Samoa were described by 
Marples (1955). 
In the descriptions the measurements were 
made with an eyepiece micrometer and are 
given in millimetres. The leg indices are de- 
rived by dividing the length of each leg by 
the length of the carapace, and the tibial 
indices, which give a measure of the stoutness 
of the legs, by dividing the combined lengths 
of the tibia and patella by the proximal 
breadth of the patella. The eye measurements 
are given in direct scale readings, so indicate 
the proportions only.
