== Description ==
Body short, 39 segments, 16 pairs of [elytra](/source/elytron_(Annelida)). Anterior margin of [prostomium](/source/prostomium) with a pair of acute anterior peaks. Lateral antennae inserted ventrally (beneath prostomium and median antenna). Palps, antennae, dorsal and ventral cirri with papillae. Notochaetae about as thick as neurochaetae. Unidentate and bidentate neurochaetae present.[Ruff, R.E. (1991) A new species of Bathynoe (Polychaeta: Polynoidae) from the northeast Pacific Ocean commensal with two species of deep-water asteroids. Ophelia Supplement 5, 219–230]
Species of ''Bathynoe'' may have about 28 to 43 segments and 10–24 pairs of [elytra](/source/elytron_(Annelida)). The elytra are large but leave the middle of dorsum uncovered, they have several large mounds and are covered with much smaller conical microtubercles. The [prostomium](/source/prostomium) is bilobed and cephalic peaks are absent, The median antenna is dorsal on the anteriormost part of the prostomium with the lateral antennae in a ventral position. The dorsal surface of the body has 1 to 3 tubercles on all or most segments. The [neuropodia](/source/Parapodia) are rounded and the [neurochaetae](/source/Chaeta) have transverse rows of very fine teeth and all have a simple unidentate tip. [Notochaetae](/source/Chaeta) are absent.
