Genus Perinereis Kinberg, 1865

Perinereis Kinberg, 1865: 175 .

Type species

Perinereis novaehollandiae Kinberg, 1865 , by subsequent designation ( Hartman 1948: 72), junior synonym of Perinereis amblydonta ( Schmarda, 1861) after Ehlers (1904: 28).

Remarks

Nereidids with pharynx armed with conical paragnaths on maxillary and oral rings, some species with bar-shaped paragnaths on Area IV, with transverse bars on Area VI (in a variable number), short or long. Notopodia with homogomph spinigers, neuropodia with homogomph and heterogomph spinigers and heterogomph falcigers with short and long blades. Perinereis has been divided into informal groups and subgroups depending on the ornamentation in Area VI of the pharynx, as well as on the development of the dorsal ligule of the posterior notopodia ( Hutchings et al. 1991). Recently, Villalobos-Guerrero (2019) included novel diagnostic characters of the marks in the pharynx between the right and left Area VI and Area V. In addition, he re-described and included in Perinereis two species previously included in Nereis and Neanthes Kinberg, 1865 . Villalobos-Guerrero et al. (2021) reviewed the species of Group 2 of Perinereis (which present two bars in Area VI), and transferred three species to Perinereis . A recent contribution by Teixeira et al. (2025) included the descriptions of 13 new species, increasing their number to 89 species, being the second largest genus of Nereididae in number of species.

Distribution

The species of Perinereis are mainly distributed in the intertidal to the subtidal zone, in tropical to temperate localities in soft bottoms, inhabiting among sessile organisms, fissures between rocks, between patches of mytilid mollusks, or other sessile organisms. The deepest species recorded is from deep waters off Greece, Perinereis tenuisetis Fauvel, 1915 , collected in a depth of 3848 m ( Faulwetter et al. 2017).
