New sublittoral species of Laonice (Annelida: Spionidae) from Southern Asian coasts

Four new species of Laonice (Annelida: Spionidae) are described from the southern and southeastern coasts of Asia: L. (Laonice) persica sp. nov., L. (Laonice) siamica sp. nov., L. (Sarsiana) apicelamella sp. nov. and L. (Sarsiana) andamanica sp. nov. Materials were collected within the scope of different environmental surveys performed by the consulting company Creocean, ranging from the Persian Gulf (Indian Ocean) on the west, to the Gulf of Siam (Pacific Ocean) on the east. In addition, specimens found in the Gulf of Siam are tentatively attributed to L. (Sarsiana) sinica, and an English translation of the species description is provided for the first time. Different species subgroups within L. (Sarsiana) are also recognized based on key morphologic characters, though their phylogenetic relevance requires further confirmation. The scientific value of biological material collected during environmental surveys is emphasized, and contractors are encouraged to deposit reference collections in public natural history collections.Norwegian Research Council Project 233635/H30; Consolidated Research Group on Marine Benthic Ecology of the Generalitat de Catalunya (2021SGR00405);info:eu-repo/semantics/publishedVersio

New species of Scolelepis (Polychaeta, Spionidae) from the Norwegian coast and Barents Sea with a brief review of the genus

The species Scolelepis finmarchicus sp. nov. is described from the Norwegian and Barents Seas along the northern Norwegian coast and Kola peninsula. The occurrence of this species in the Kola Bay could be seen as a sign of climate warming in the area. Taxonomic issues existing in the genus Scolelepis within the area along the Norwegian coast and in the Barents Sea are briefly touched upon. Seven species belonging to Scolelepis have recently been recorded from the Atlantic sector of the Arctic. Scolelepis (S.) matsugae Sikorski, 1994 is newly synonymized with S. (S.) laonicola (Tzetlin, 1985). This article provides a brief review of Scolelepis together with an identification key for the genus from the Atlantic sector of the Arcti

Laonice species (Polychaeta, Spionidae) from the Whittard Canyon (NE Atlantic) with descriptions of two new species

Four species of Laonice (Annelida: Spionidae) were collected from the lower bathyal depths (3300–3700 m) in the Whittard Canyon, NE Atlantic. Two are herewith described as new species: Laonice whittardensis sp. nov. and Laonice natae sp. nov. The other two are Laonice blakei Sikorski & Jirkov, 1988 and Laonice magnacristata Maciolek, 2000. Laonice whittardensis has genital pouches appearing from chaetiger 3, prostomium free of peristomium and bidentate hooks. Laonice natae belongs to the subgenus Appelloefia nov. with prostomium distinct from the peristomium, more than two vertical rows of capillaries in several anterior chaetigers, genital pouches present on a limited number of segments or totally absent. However, the absence of pronounced anterior widening of the body together with anterior branchiae, which are remarkably (nearly twice) longer than the notopodial postchaetal lobes, the narrow lanceolate notopodial postchaetal lobes, the pronounced pointedness of all postchaetal lobes (both notopodial and neuropodial) in the anterior half of body at least, and absence of genital pouches and the size of the body all distinguish L. natae from other species belonging to this subgenus. An identification key to all nine known deep-water (>400 m depth) Laonice species in North Atlantic is given and four previously recognized sub-generic groups are formally named: Laonice, Sarsiana subgen. nov., Appelloefia subgen. nov., Norgensia subgen. nov

Two new deep-sea species of Laonice (Annelida: Spionidae) from the Mediterranean Sea

Este artículo contiene 12 páginas, 4 figuras.Two new deep-sea species of the genus Laonice belonging to the subgenera Sarsiana and Appelloefia respectively, are described from the Mediterranean Sea. Complete specimens of the subgenus Appelloefia were studied for the first time, and the new information collected raised questions on the boundaries between the subgenera Appelloefia and Norgensia. The presence of characters in L. barcinensis sp. nov. previously considered to be exclusive to each these two subgenera suggests that they should be regarded as synonymous. The name Appelloefia being given precedence here, according to the Principle of the First Reviser. A correction is made regarding the depth range of Laonice rasmusseni Sikorski & Pavlova, 2018.Financial support was provided by the Norwegian Research Council (Project 233635/H30, “Environmental management of petroleum activities in the Barents Sea: Norwegian-Russian collaboration” and NFR 280724 “Environmental monitoring of Arctic coastal ecosystems: Sensitivity to petroleum pollution (Arctic EcoSens)”), DOS MARES Research Project (Ref.
