New species and records of deep-water Orbiniidae (Annelida, Polychaeta) from the Eastern Pacific continental slope, abyssal Pacific Ocean, and the South China Sea

Abstract

Eighteen species of Orbiniidae, 15 new to science, are reported from deep-sea habitats in the Pacific Ocean and the South China Sea. The collection includes specimens from continental slope and abyssal soft sediments as well as hydrothermal vent and methane seep sites. New collections of Califia calida Hartman, 1957, Naineris uncinata Hartman, 1957, and Phylo nudus (Moore, 1911) allow redescription and new distributional records of these species to be documented. Five species of Leitoscoloplos: L., cliffordi n. sp., L. gordaensis n sp., L. lunulus n. sp., L. sahlingi n. sp., and L. williamsae n. sp. are described together with a new species of Berkeleyia, B. lelievre n. sp., two new species of Scoloplos: S. californiensis n. sp. and S. sparsaciculus n. sp., and a new species of Leodamas, L. bathyalis n. sp. In addition, six new species of Orbiniella are described: O. abyssalis n. sp., O. eugeneruffi n. sp., O. grasslei n. sp., O. longilobata n. sp., O. rugosa n. sp., and O. tumida n. sp.

Abyssal fauna of polymetallic nodule exploration areas, eastern Clarion-Clipperton Zone, central Pacific Ocean: Amphinomidae and Euphrosinidae (Annelida, Amphinomida)

“…These data build up on previous taxonomic work on annelids from the target areas (Wiklund et al 2019;Drennan et al 2021;Neal et al 2022) as well as wider CCZ area (Janssen et al 2015;Blake 2019;Bonifácio and Menot 2019) and ultimately provide further insights into annelid species distribution in the deepsea realm. Up to this date, 52 annelid species have been formally described from CCZ, with the focus on families Spionidae (Paterson et al 2016;Neal et al 2022), Orbiniidae (Blake 2017(Blake , 2020, Polynoidae (Bonifácio and Menot 2019), Cirratulidae (Blake 2016(Blake , 2019, Opheliidae, Scalibregmatidae, and Travisiidae (Wiklund et al 2019), Syllidae (Maciolek 2020) and Nereididae (Drennan et al 2021).…”

A new species and new recorded species of Orbiniidae Hartman, 1942 (Annedia: Polychaeta) from China

“…Hartman (1957) reviewed this genus and described four species in detail, including the type species, P. felix Kinberg. Subsequently, Day (1961;1977), Mohammad (1980), andHartmann-Schröder &Rosenfeld (1990), Blake (2017Blake ( , 2020Blake ( , 2021 described additional Phylo species. According to these literature, thirteen species of Phylo are considered valid (Read & Fauchald, 2021;Blake, 2021).…”

“…Hartman (1957) reviewed this genus and described four species in detail, including the type species, P. felix Kinberg, 1866.
