Thirteen cirratulid species from the Hawaiian, Mariana and Marshall Islandsare described. Nine species are new to science: Aphelochaeta arizonae sp. nov., Aphelochaeta honouliuli sp. nov., Caulleriella cordiformia sp. nov., Chaetozone michellae sp. nov., Chaetozone ronaldi sp. nov., Monticellina anterobranchiata sp. nov., Monticellina hanaumaensis sp. nov., and Tharyx tumulosa sp. nov., from Oahu, Hawaii and Aphelochaeta saipanensis sp. nov., from Saipan in the Mariana Islands. Dodecaceria fewkesi and Monticellina nr. cryptica are newly recorded from the Hawaiian Islands. Dodecaceria laddi is widely distributed in the western Pacific and material collected from the Hawaiian, Mariana andMarshall islands is described. We provide SEM photographs for all species in addition to line drawings and methyl green staining pattern photographs for the new species.

A New Species

Polychaetes from the Mariana Islands of Guam and Saipan have been characterized in previous studies but a thorough taxonomic study of the cirratulids has only been possible recently. Here we report on two new records,Caulleriella pacificaandChaetozone flagellifera, and a new species,Monticellina lueldredgei, sp. nov. The speciesC. pacificais newly recorded for the western Pacific whileC. flagelliferais reported for the first time since its original description. The new speciesM. lueldredgeiis unique in the genus with respect to the ultrastructure and segmental origin of the modified capillaries as well as for the distinctive methyl green staining pattern.

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.

The Western Pacific

Some brachyuran crab species of the Western Pacific appear to be widespread throughout the region and distributed across a large geographic area, without obvious phylogeographic structuring. In the present study, we describe a new species of Parasesarma that appears to be restricted to Western Pacific islands (so far Guam, Palau, Vanuatu, Fiji, Wallis and New Caledonia). Comparisons of partial sequences of the COX1 gene show that individuals of this species, though from relatively isolated and widely separated islands, are monophyletic and, surprisingly, genetically uniform. These results give credence to the hypothesis that these oceanic islands serve as ‘stepping stones’ for the current-mediated dispersal and genetic homogenisation of coastal–littoral marine species. Morphologically, the new species differs most significantly from similar congeners in the tuberculation pattern of the chelar dactyli, whereas genetically it is markedly divergent from other morphologically similar species of Parasesarma, with a minimum COX1 p-distance of 6.9%. With such evidence, the new species is here formally described as Parasesarma daviei sp. nov. It is the fifth species of Parasesarma reported from oceanic islands of the Western Pacific. Compared to other congeners, P. daviei sp. nov. shows a close relationship with a clade including P. calypso. Therefore, P. calypso (De Man, 1895), and three of its former subspecies or varieties were subjected to a closer examination and are here rediagnosed and illustrated. In consequence, we suggest full species status for P. kuekenthali (De Man, 1902), P. lanchesteri (Tweedie, 1936), and P. ellenae (Pretzmann, 1968).

A New Species

The taxonomy and distribution of Pacific Annonaceae are reviewed in light of recent changes in generic delimitations. A new species of the genus Monoon from the Solomon Archipelago is described, Monoon salomonicum I.M.Turner & Utteridge sp. nov., together with an apparently related new species from New Guinea, Monoon pachypetalum I.M.Turner & Utteridge sp. nov. The confirmed presence of the genus in the Solomon Islands extends the generic range eastward beyond New Guinea. Two new species of Huberantha are described, Huberantha asymmetrica I.M.Turner & Utteridge sp. nov. and Huberantha whistleri I.M.Turner & Utteridge sp. nov., from the Solomon Islands and Samoa respectively. New combinations are proposed: Drepananthus novoguineensis (Baker f.) I.M.Turner & Utteridge comb. nov., Meiogyne punctulata (Baill.) I.M.Turner & Utteridge comb. nov. and Monoon merrillii (Kaneh.) I.M.Turner & Utteridge comb. nov. One neotype and four lectotypes are designated. The geographic patterns exhibited by nine native Annonaceae genera, that range in the Pacific beyond New Guinea, are discussed.
