Abstract
Two species of Serolidae, Caecoserolis carinata sp. nov. and Caecoserolis bicolor sp. nov. are described from northern New Zealand waters, the first record of the genus from New Zealand. A third species, a juvenile is recorded as Caecoserolis sp. All are deep-water species. C. carinata can be identified by the median row of prominent tubercles, and was collected from the southern New Caledonia Trough, Tasman Sea at depths of 2930–3184 m; C. bicolor has paired nodules on the head linked by a V-shaped ridge, a broad body, widest at pereonites 3 and 4, and occurs off Hawkes Bay, off eastern North Island, at depths of 2119–2337 m.
