Remarks.
The
New Zealand
specimens conform well to the
type
description and are the first records of the species outside Tasmania. The rostral spination of the
New Zealand
specimens (9 or 10 dorsal of which 4 are postorbital; 16–20 ventral) is within the expected range of variation for the species (9 dorsal of which 4 are postorbital; 15–18 ventral;
Taylor & Poore 1998
), as is rostral length (1.22–1.61 cl. versus 1.05–1.46). Of the
three males
and
nine females
examined, the major pereopod 2 is on the right in all specimens except for
one male
and
four females
. Most specimens were collected together with sponges and mixed corals including primnoids (
Thourella
sp.,
Acanthogorgia
sp.
) and
Madrepora oculata
.
Distribution.
Seamounts off south-eastern Tasmania and now from seamounts on the Chatham Rise,
New Zealand
;
900–1448 m
.
