Diagnosis

provided by World Register of Marine Species
Original diagnosis by Pettibone (1971: 31): ''Prostomium subpyriform, with paired frontal antennae, biarticulate palps, and two pairs of eyes. Tentacular segment apodous and achaetous; four pairs of tentacular cirri with distinct cirrophores. Parapodia of first two setigers subbiramous; notopodium represented by dorsal cirrus and single ligule. Dorsal cirri at bases of upper notopodial ligules. Notopodia with two ligules, upper one sometimes fused with dorsal cirri (in posterior notopodia of zebra; from setiger 3 on, in bahamensis). Neuropodia with acicular lobes and lower ligules. Ventral cirri short, tapered. Notosetae homogomph spinigers and, more posteriorly, homogomph falcigers. Neurosetae homogomph and heterogomph spinigers and heterogomph falcigers. Pygidium with paired anal cirri. Pharynx with paired jaws, without paragnaths or papillae (latter present on oral ring in bahamensis).''

Diagnosis

provided by World Register of Marine Species
as emended in Tanaka & Sato (2017: 428) "Prostomium with entire anterior margin, one pair of antennae, one pair of biarticulated palps with conical palpostyles, and four pairs of tentacular cirri with distinct cirrophores. Eyes present or absent. Pharynx with paired jaws; maxillary ring without papillae and paragnaths; oral ring without paragnaths, with or without papillae (papillae present in R. bahamensis Hartmann-Schröder, 1958). Parapodia of first two chaetigers uniramous; notopodium with dorsal cirrus; single notopodial ligule present or absent. Notopodia of following chaetigers with dorsal cirrus and ventral ligule; dorsal ligule and prechaetal lobe present or absent. Neuropodia with acicular lobe, postchaetal lobe, ventral ligule, and ventral cirrus; prechaetal lobe absent. Notochaetae: homogomph spinigers and falcigers present; falcigers often replacing spinigers on posterior chaetigers. Neurochaetae: homogomph spinigers present in upper neurochaetae, together with heterogomph falcigers or spinigers; heterogomph falcigers present in lower neurochaetae, with or without heterogomph spinigers."
