Two new species of Marphysa (Annelida, Eunicidae) from southern Australia.

Abstract

Two new species of Marphysa Quatrefages, 1866 are described from the southeast coast of Australia. With the presence of only compound spinigers and the branchiae present over many chaetigers, Marphysa baudini n. sp. belongs to the Sanguinea-group. This species has ventral cirri with an inflated base and digitiform tip and thick and wide anodont pectinate chaetae, with 3–5 internal long and thick teeth. With the presence of only compound falcigers, Marphysa davidattenboroughi n. sp., belongs to the “Aenea-group”. This species is characterised by the presence of a bilobed prostomium, a single pair of pygidial cirri and by the presence of thick, and wide anodont pectinate chaetae with 4–6 long internal and thick teeth.

“…Marphysa species inhabit a wide range of habitats, either in soft sediments or rocky ground, from intertidal to shallow subtidal depth, and are commonly found in estuarine or sheltered habitats (Abdullah et al in review;Zanol et al 2016;Martin et al 2020). Three species have recently been described from the deep sea (Lavesque et al 2023). Taxonomic studies of Marphysa species have increased considerably since the redescription of the type species, M. sanguinea (Montagu, 1813) and the designation of a neotype by Hutchings and Karageorgopoulos (2003); and later by molecular sequencing (Zanol et al 2010).…”
