Diagnosis Prostomium anteriorly rounded with ventral sulcus. Five prostomial appendages arranged in an arc on posterior margin of prostomium. Eyes present, round and dark. Maxillary formula: 1+1, 8+9(8), 9+0, 5(6)+10, 1+1. Branchiae pectinate, present from chaetiger 14–16 to 31–33 with 8–13 long filaments. Dorsal cirri always well developed, slightly longer but thinner in postbranchial chaetigers. Ventral cirri shorter than dorsal cirri, bluntly triangular in pre-branchial region, becoming bluntly conical and thinner through the body. Postchaetal lobes well developed in anterior part of body, becoming inconspicuous from about chaetiger 45 onwards. Three or four light brown aciculae in prebranchial chaetigers, decreasing to two in anterior part of branchial region and to one thereafter. Subacicular hooks light brown, bidentate, commencing from chaetiger 33–37 and present in all following chaetigers; most often one per chaetiger but sometimes two in posterior part of body. Compound chaetae all bidentate falcigers, with two sizes of blades, short ones about 50 μm, long ones about 90 μm. One type of pectinate chaetae identified: narrow, isodont with 2–5 long and slender internal teeth. Posterior pectinate chaetae, if different, unknown. Pygidium unknown.

Phylogeny See author's tree figure (figure 5). Pinsivy et al (2025: 197) comment that "Based on our molecular analysis, the status of the genera Marphysa and Paucibranchia is still not clear. Indeed, Paucibranchia species seem to be separated from the main Marphysa clade, but M. regalis is a sister species of P. glemareci sp. nov., and Marphysa papuaensis Lavesque, Daffe, Glasby, Hourdez & Hutchings, 2022 is isolated. When they described M. papuaensis, Lavesque et al. (2022) hesitated as to which genus it should be assigned to as this species has a limited number of branchial segments. However, the maxillae I (Lavesque et al. 2022: fig. 6D) are more similar to those of Marphysa (the base arch lacking a curvature in the basal inner edge) than those of Paucibranchia (the base straight with a curvature in the basal inner edge) (Molina-Acevedo 2018). A phylogenetic study based on molecular data of the genera Marphysa, Paucibranchia, and closely related Treadwellphysa Molina-Acevedo & Carrera-Parra, 2017 is really necessary to test their monophyly and placement within Eunicidae (Zanol, pers. comm.)."
