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.
