Geographical distribution and bathymetry
N
New Zealand
(
Kermadec Islands
) in less than
100 m
deep. In
New Caledonia
,
Loyalty Islands
and the Coral Sea typically at depths between 200 and
400 m
.
Specimens from the
Philippines
identified as
A. bruuni
correspond most likely to a different species (Tenorio
et al.
2018).
Remarks
Medium-sized to moderately large (maximum shell length
75 mm
) conical shell with a low to moderate spire straight or slightly concave and an angulate shoulder. Protoconch multispiral of about 3 whorls (
Fig. 50L
). Radular tooth (
Fig. 50M
) rather large, narrow and elongated with the anterior section slightly shorter than the posterior section. The tooth is serrated with a fairly long row of small denticles ending in a small terminating cusp. Barb and blade very short, almost equal in size. Basal spur is present on top of the large base. This is possibly the most abundant species among the lots from
New Caledonia
examined in the present work, with more than
550 specimens
. In the phylogeny of New Caledonian cone snails presented in
Fig. 2
,
C.
(
A.
)
bruuni
appears sister to species in the (sub)genus
Phasmoconus
. However, in a more general phylogeny, the
Afonsoconus
clade is sister to the
Textilia
clade (Tenorio
et al.
2018;
Puillandre
et al.
2014
), which contains fish-eating species with harpoon-shaped radular teeth such as
Conus
(
Textilia
)
dusaveli
(H.
Adams, 1872
)
or
Conus
(
Textilia
)
cervus
Lamarck, 1822
. Although these two species occur in
New Caledonia
, no live specimens were available, so they were not included in our phylogenetic analysis.
