| Popis: | Due to the extreme scarcity of specimens, little is known about the biodiversity and biogeography of the barnacles of the genus Waikalasma Buckeridge, 1983 (Thoracica: Waikalasmatidae Ross and Newman, 2001), which inhabit the deep sea of the Southwest Pacific. Previous studies reported only a single living species, W. boucheti Buckeridge, 1996, from Vanuatu. In the present study, the collections by French deep-sea expeditions off New Caledonia (NORFOLK 1 & 2, EBISCO, SMIB 2, SMIB 4, SMIB 8, BIOCAL, MUSORSTOM 6, MUSORSTOM 4, MUSORSTOM 5, BATHUS 2), the Solomon Islands (SALOMON 1), Vanuatu (BOA1) and Papua New Guinea (BIOPAPUA) yielded specimens of Waikalasma species from 500 to 800 m depth. From molecular (DNA barcode region cytochrome c oxidase subunit I (COI) and 12S gene) and morphological analysis, a new species Waikalasma dianajonesae sp. nov., and W. boucheti were identified. From molecular phylogenetic analysis, sequence divergence in the DNA barcode region between W. dianajonesae sp nov. an... |
