Abstract A second species of
Neophrynichthys is
described from 20 specimens collected from the Campbell Plateau, south of South
Island, New Zealand. It differs from its sole congener,
N. latus, in
having 25-26 pectoral rays (versus 22-24), cirri on head more than twice as
large, half as few (c.
50 versus >100), and generally absent from the
mid- region behind the eyes (versus being relatively dense), and in spotted
colour pattern covering much less than 50% of the dorsal surface of the head
(versus >50%). This new species is the sixth psychrolutid known from New
Zealand. The genus
Neophrynichthys is formally diagnosed by two
synapomorphic characters unique among psychrolutids: having light spots on a
dark ground colour and having an open fourth and fifth infraorbital, fifth and
sixth cranial arch, medial extrascapular, and posterior tabular of the
pterotic.
