[[ Genus Parmaturus Garman ZBK ]]

Discussion

Compagno et al. (2005) mention that the New Zealand species P. macmillani ZBK also occurs on the submarine ridge south of Madagascar. An examination of CSIRO material collected from the Madagascar Ridge caused the present authors to consider that another two new Parmaturus ZBK species occur in this area: a catshark with small denticles and beige coloration, the other species with larger denticles, a dark brown body, and a dark brown ventral snout. Similarly, unidentified material from New Zealand, sent to the authors by Andrew Stewart(NMNZ), represent two new large species (ca 100 cm TL) that both have very rough denticles. These undescribed species will be the subject of future manuscripts and are not included in the following key to Indo-West Pacific species.
