Abstract: The ants of Samoa have been well studied compared with those of
other Pacific island groups. Using Wilson and Taylor's (1967) specimen records
and taxonomic analyses and Wilson and Hunt's (1967) list of 61 ant species
with reliable records from Samoa as a starting point, we added published,
unpublished, and new records of ants collected in Samoa and updated taxonomy.
We increased the list of ants from Samoa to 68 species. Of these 68 ant species,
12 species are known only from Samoa or from Samoa and one neighboring
island group, 30 species appear to be broader-ranged Pacific natives, and 26
appear to be exotic to the Pacific region. The seven-species increase in the
Samoan ant list resulted from the split of Pacific Tetramorium guineense into the
exotic T. bicarinatum and the native T. insolens, new records of four exotic
species (Cardiocondyla obscurior, Hypoponera opaciceps, Solenopsis geminata, and
Tetramorium lanuginosum), and new records of two species of uncertain status
(Tetramorium cf. grassii, tentatively considered a native Pacific species, and
Monomorium sp., tentatively considered an endemic Samoan form).
