Spiders from Some Pacific Islands, Part V 
B. J. Marples 1 
A COLLECTION OF spiders from various Pacific 
islands was entrusted to me for examination by 
the Director of the Bernice P. Bishop Museum 
in Honolulu, to whom I am indebted. There 
were 146 tubes, mostly containing a number of 
specimens, and they had been collected by dif- 
ferent people at different times from islands 
between New Caledonia in the west and Tahiti 
in the ease Five new species are described and 
also four allotypes, and a number of additions 
to faunal lists have been made. The islands, 
or island groups, will be mentioned in alpha- 
betical order, and the descriptions given at the 
end. Unless otherwise stated the specimens are 
in the Bernice P. Bishop Museum. 
AITUTAKI 
Aitutaki is an island, partly volcanic and 
partly of coral, lying 140 miles north of Raro- 
tonga. It has 6 square miles. Twenty-four species 
have been recorded and the present collection 
adds three more. Smeringopus pallidus (Black- 
wall) (formerly S. elongatus Vinson) has a very 
widespread distribution and has been recorded 
in Samoa and in Rarotonga and the Northern 
Cook Islands. Chiracanthium longimanum L. 
Koch has previously been recorded only as far 
east as Tonga and Samoa. The third new record 
is a salticid here described as Flacilla kraussi 
n. sp. 
LINE ISLANDS 
These are very isolated atolls situated more 
or less on the equator, east of the Gilbert Islands 
and north of the Tokelau Islands. The fauna of 
such islands is of course poor in the extreme, 
and consists for the most part of species ac- 
cidentally introduced by man. This was well 
shown by Sakagami ( 1961 ) for Marcus Island,

which lies in a very isolated position to the 
northeast of the Mariana Islands. In 1902 only 
one spider species was present, while in 1961 
there were four: a pholcid, an epeirid, a salticid, 
and Heteropoda venatoria. In the present collec- 
tion 15 species were present from six islands, 
and six of these have been left unidentified. It 
was felt that they may have been introduced 
from anywhere and are not part of the normal 
Pacific fauna. To describe them as new would 
only tend to cause confusion. Table 1 shows the 
distribution of the species between the islands. 
NEW CALEDONIA 
About 150 species have been recorded from 
New Caledonia, many of them not extending 
into the more easterly islands but no doubt 
having a wider distribution towards the north- 
west. In the present collection 14 species have 
been identified, all but two of which have been 
recorded previously. The two new records are 
Prychia gracilis L. Koch, previously known 
from New Hebrides and Fiji, and Poicilopachys 
bispinosa (Keyserling) (formerly Cyrtarachne ) , 
known from New Hebrides and Samoa. 
SAMOA 
The spider fauna of Upolu is probably as 
well known as that of any of the Pacific islands. 
The larger island of Savaii to the west, and the 
smaller Tutuila to the east, are less well known. 
However, as their distances from Upolu are 
only 8 and 47 miles respectively, their faunae 
are probably very similar. All are large, moun- 
tainous, volcanic islands. 
In 1955 I published a list of the spiders of 
Upolu, including 123 species. Since then six 
have been added: Dr ass odes ciusi Berland, Clubi- 
ona upoluensis n. sp., Euryattus lautus Keyser- 
ling, Trite longipalpis Marples, Leucauge granu- 
lata Walckenaer, and Epeira pogisa Marples.
