1 Neopolyodontes gen. nov.
Ommatophores absent, Prostomium bilobod with four eyes. Two antennae, median antennae absent. Smooth elytra cover the head, but further back most of the dorsum are naked. Notoseta absent, neuroseta include: brushlike seta, serrulate seta, equiosetum-like seta, capillary seta, and composite setta.
The Neopolyodontes gen. nov. differs from other genera in the following respects (Tab).
2 Neopolyodontes lepidus sp. nov.
The holotype consists of 39 segments measuring 17mm in length and 5.2mm in width (including parapodia). Prostomium with four eyes and two antennae, median antennae absent. Anterior pair of eyes is larger than posterior pair. Smooth elytra cover the head but further back most of the dorsum
is naked. The notoseta and neuroseta include: brushlike seta, serrulate set equisetum-like seta, capillary seta and composite seta.
3 Neopanthalis muricatus sp. nov.
Neopanzhalis Strelzov, 1968
The holotype consists of 29 segments measuring 29 mm in length and 10 mm in width (including parapodia).
Three antennae present. Lateral antennae short, fused, and appeared at the end of hill-form eminence. The palps with many small dents on the dorsal surface.
The Neopanzhalis muricatus sp. nov. differs from Neopanzhalis pelamida in the following respects:
