A new deep-water catshark species,
Apristurus exsanguis, is
described based on twenty-nine specimens collected from the waters around New
Zealand. It has strong similarities with
Apristurus sp. B (Paulin et
al., 1989) from New Zealand,
Apristurus sp. A (Last & Stevens, 1994)
from Australia and
Apristurus japonicus Nakaya, 1975, from Japan, but
can be separated from species `A' and `B' by colouration, relative dorsal fin
sizes and position, and spiral valve count; and from
A. japonicus by
counts of spiral valves, tooth rows and monospondylus vertebrae.
