Geographical distribution and bathymetry
New Caledonia
: Norfolk Ridge and
Loyalty Islands
, typically at depths between 300 and
600 m
, although some individuals come from beyond
1000 m
deep. Some specimens have been sampled in the Coral Sea (Argo Bank) and in the Grand Passage area. A couple of empty shells resembling
P. neocaledonicus
from Aliguay Island,
Philippines
have been examined, but their identity was not confirmed by radular or DNA studies. This observation might suggest an extension of the distribution range to the
Philippines
, but would require additional evidence (Tenorio & Castelin 2016).
Remarks
Medium-sized to moderately large (maximum length 92.0 mm). Protoconch multispiral of 3 or more whorls, white to pale violet-brown (
Fig. 10L
). Radular tooth (
Fig. 10M
) rather small. Anterior portion of tooth shorter than posterior section, with pointed blade covering about one half of apical portion of tooth. External cusp present, not much widened laterally and with indistinct serrations, with only 0–3 small blunt denticles. Characteristic fringe of closely spaced projections pointing towards apex located immediately below waist. Shaft fold present. Large and prominent basal spur on top of slanted base of tooth. In the phylogeny (
Fig. 2
), the specimens of
P. neocaledonicus
are grouped in a clade sister to another large one containing specimens of
P. teramachii
mixed with some individuals of
P. smirnoides
.
