Bathymoorea Pettibone, 1967: 10 . – Fauchald, 1977: 60.

Type species: Polynoe (?) renotubulata Moore, 1910 .

Diagnosis (emended): Short body, dorsoventrally flattened, up to 33 segments. Prostomium bilobed. Frontal filaments absent. One pair of large eyes present. Median and lateral antennae present; lateral antennae inserted subterminally on prostomium extensions. Facial tubercles present. Tentaculophores with acicula and chaetae ( Bathymoorea lucasi sp. nov.) or achaetous ( Bathymoorea renotubulata ). Pharynx with two pairs of jaws. Dorsal tubercles present. Elytrophores large, up to 14 pairs, on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 26 and 28. Parapodia subbiramous; noto- and neuropodia with elongate acicular lobe; tips of noto- and neuroaciculae penetrating epidermis. Notochaetae with spinous rows, neurochaetae numerous. Nephridial papillae from segment 5 or 6.

Remarks: Pettibone (1967) erected the genera Bathyadmetella Pettibone, 1967 and Bathymoorea and emended Admetella McIntosh, 1885 based on bathyal specimens from the Central and North-eastern Pacific. According to Pettibone (1967) and Uschakov (1982), these genera share some similarities: prostomium with paired large eyes, lepidonotoid-like ceratophores of the lateral antennae, bulbous facial tubercles, long neuroacicular lobes and neurochaetae of one type, numerous, long and flattened. Uschakov (1977) created the subfamily Admetellinae to include Admetella and Bathyadmetella , both possessing antennal scales or sheaths. As pointed out by Uschakov (1982), the position of Bathymoorea , without scales or sheaths on the antennae, remained unknown until now. The genus is here emended in order to include the presence of chaetae on the tentacular segment and nephridial papillae from segment 5 or 6 observed in Bathymoorea lucasi sp. nov.
