Opheliidae (Annelida: Polychaeta) from the western Pacific islands, including five new species

Abstract

Intertidal, shallow subtidal and deep-water opheliids from the Hawaiian Islands, Guam in the Mariana Islands and Tutuila in American Samoa were examined and nine species are described, five of which are new. Armandia garretti sp. nov. and A. circumpapillata sp. nov. are new species proposed for previous records of A. intermedia Fauvel, 1902 from Hawaii. Armandia cf. paraintermedia Parapar & Moreira, 2015 is recorded from intertidal muddy bottoms of Tutuila and A. amakusaesis Saito, Tamaki & Imajima, 2000 from subtidal regions in Guam. Polyophthalmus mauliola sp. nov. is described from Hawaiian material and a comparative table with relevant morphological features of eight species of this genus is presented. Ophelina cf. chaetifera (Hartman, 1965) and Ophelina abranchiata Stop-Bowitz, 1948 are new records to Hawaii from up to 507 m depth, Ophelina kohni sp. nov. is described from shallow waters of Guam and Ophelina manana sp. nov. is described from Mamala Bay, Oahu.
