Body of relatively small size, with few chaetigers. Palps elongated, at least partially fused for most of their length. Prostomium with 3 antennae; eyes absent. Peristomium with 1 pair of ovate to digitiform peristomial cirri. Dorsal cirri smooth, long, filiform, frequently coiled over dorsum, absent on chaetiger 2. Ventral cirri digitiform, inserted medially to distally in parapodial lobes. Parapodial lobes relatively long, with pre- and postchaetal lobes. Compound chaetae heterogomph, with unidentate, slender blades. Pharyngeral tooth absent. Reproduction unknown (

All the species in this genus are quite similar to each other, differing mostly by the morphology of palps, presence/absence of dorsal cirri on chaetiger 2, details on the structure of the parapodial lobes, length of the blades of compound chaetae, and presence of parapodial glands. Also, the number of chaetigers in adults seems to be constant for each species, which is not a common feature for syllids. With the amendment to the description of
