NIWA 87164 (2 specimens) Stn TAN1206/144, 37.53° S, 177.29° E, 1182 m, 28/04/2012. Description of holotype. Paradota species 20 mm long, 4 mm wide, 4 mm high (preserved). Body form long, cylindrical with slightly bulbous posterior end (possible preservation artefact), bulbous end skin is thinner than rest of the body. Skin contracted, covered in small papillae giving a granular texture. No tube feet. Mouth is terminal, surrounded by a tentacle crown with 12 equal sized tentacles of peltato-digitate shape with 4-5 digits per side of each tentacle, which become smaller nearer the tentacle trunk. Paratypes follow the general description above with the following differences: specimens are up to 40 mm long, 4 mm wide and 4 mm high (preserved). The bulbous end can be either anteriorly or posteriorly located. Due to the small size of specimens the paratypes were extensively dissected. Internally the majority of the coelomic cavity is occupied by sediment filled intestine. The longitudinal muscles are large, up to 2 mm high and wide, divided. One large (1.5 mm) polian vesicle (structure responsible for maintaining water vascular system pressure) is present with 2-3 smaller thinner ones. Gonads not visible in dissected specimens but tubule like strands present posteriorly which may be undeveloped gonad material. Calcareous ring consists of 12 large ...
