Abstract: Nautiloids are a charismatic group of marine molluscs best known for their rich fossil record, but today they are restricted to a handful of species in the family Nautilidae from around the Coral Triangle. Recent genetic work has shown a disconnect between traditional species, originally defined on shell characters, but now with new findings from genetic structure of various Nautilus populations. Here, three new species of Nautilus from the Coral Sea and South Pacific region are formally named using observations of shell and soft anatomical data augmented by genetic information: N. samoaensis sp. nov. (from American Samoa), N. vitiensis sp. nov. (from Fiji), and N. vanuatuensis sp. nov. (from Vanuatu). The formal naming of these three species is timely considering the new and recently published information on genetic structure, geographic occurrence, and new morphological characters, including color patterns of shell and soft part morphology of hood, and will aid in managing these possibly endangered animals. As recently proposed from genetic analyses, there is a strong geographic component affecting taxonomy, with the new species coming from larger island groups that are separated by at least 200 km of deep water (greater than 800 m) from other Nautilus populations and potential habitats. Nautilid shells implode at depths greater than 800 m and depth therefore acts as a biogeographical barrier separating these species. This isolation, coupled with the unique, endemic species in each locale, are important considerations for the conservation management of the extant Nautilus species and populations.

Annotated checklist for stony corals of American Sāmoa with reference to mesophotic depth records https://zookeys.pensoft.net/article/34763/ ZooKeys 849: 1-170

DOI: 10.3897/zookeys.849.34763

Authors: Anthony D. Montgomery, Douglas Fenner, Robert J. Toonen

Abstract: An annotated checklist of the stony corals (Scleractinia, Milleporidae, Stylasteridae, and Helioporidae) of American Sāmoa is presented. A total of 377 valid species has been reported from American Sāmoa with 342 species considered either present (251) or possibly present (91). Of these 342 species, 66 have a recorded geographical range extension and 90 have been reported from mesophotic depths (30–150 m). Additionally, four new species records (Acanthastrea subechinata Veron, 2000, Favites paraflexuosus Veron, 2000, Echinophyllia echinoporoides Veron & Pichon, 1980, Turbinaria irregularis Bernard, 1896) are presented. Coral species of concern include species listed under the US Endangered Species Act (ESA) and the International Union for Conservation of Nature’s (IUCN) Red List of threatened species. Approximately 17.5% of the species present or possibly present are categorized as threatened by IUCN compared to 27% of the species globally. American Sāmoa has seven ESA-listed or ESA candidate species, including Acropora globiceps (Dana, 1846), Acropora jacquelineae Wallace, 1994, Acropora retusa (Dana, 1846), Acropora speciosa (Quelch, 1886), Fimbriaphyllia paradivisa (Veron, 1990), Isopora crateriformis (Gardiner, 1898), and Pocillopora meandrina Dana, 1846. There are two additional species possibly present, i.e., Pavona diffluens (Lamarck, 1816) and Porites napopora Veron, 2000.

First description of the male of Cryptothele verrucosa L. Koch, 1872 (Araneae), the type species of the genus https://zookeys.pensoft.net/article/3520/ ZooKeys 351: 31-36

DOI: 10.3897/zookeys.351.6255

Authors: Yuri Marusik, Mikhail Omelko

Abstract: The male of Cryptothele verrucosa L. Koch, 1872, the type species of Cryptothele L. Koch, 1872, known from Fiji and Samoa, is described for the first time. It is compared with the male of C. alluaudi Simon, 1893, the single properly described species of the genus.
