This report was prepared for the Bernice P. Bishop Museum, as part of the introduced marine species survey in American Samoa conducted in October 2002. The report analyzes the results of algal surveys from ten sites on Tutuila Island, American Samoa, to determine their status as invasive species. A total of 313 specimens were analyzed comprising 139 taxa: 33 Chlorophyta, 9 Phaeophyta, 84 Rhodophyta and 13 Cyanophyta.Of the 318 algae recorded for the Samoa Archipelago, 262 are now known for American Samoa. Our surveys found 65 new records for American Samoa (of which approximately 10 are new records for the Archipelago's flora). Vatia: A total of 31 taxa was recorded, comprised of 3 Cyanophyta, 5 Chlorophyta, 4 Phaeophyta, and 19 Rhodophyta. The most unusual find from this site was the collection of a small green alga Sporocladopsis erythraea. This rarely known alga was first recorded from the Red Sea. Its troubled taxonomic history is attributed to Papenfuss (1962) who erroneously synonymized it with Pilinia (a Phaeophyta). This alga was found epiphytic on the discoid holdfast of the endemic Sargassum anapense. This is the first record of this alga from the Pacific Ocean, but it may well be more common than we think. It may often be overlooked during surveys due to their minute size and cryptic habit. Fagasa: Forty-two taxa were recorded comprising of 4 Cyanophyta, 6 Chlorophyta, 4 Phaeophyta, and 28 Rhodophyta. One new addition to the Samoan flora is Chrysymenia kaernbachii a species with its type locality from Papua New Guinea and which has recently been found in Fiji and neighboring Western Samoa.
