Acanella chiliensis
Wright & Studer, 1889
Figure 8
Acanella chiliensis
Wright & Studer, 1889
: 31
, pl. IX, fig 3.
Type
:
Collected via dredge.
Station
301, in the
Messier Channel
,
Patagonia
,
Chile
. 175 fathoms depth. Indicated as deposited in the Natural History Museum, London; however we were not able to verify the location of the type specimen at the time of this publication.
For description see:
Wright & Studer 1889
Remarks:
The specimens represented by Haplotype C (
Figure 8
) have 5̄
7 mm
tall polyps with curved, slightly club-shaped sclerites with spine-like projections, which corresponds with the species description of
A. chiliensis
as described in
Wright and Studer (1889)
.
A. chiliensis
is the only valid species within the genus that has club-shaped sclerites. Published reports of
A. chiliensis
appear only once, a collection from the eastern South Pacific (Messier Channel, Patagonia,
Chile
) at
320 m
depth; our samples thus expand the known distribution of the species to the western South Pacific and Indian Ocean (New Zealand-Kermadec [n=5] and Indian [n=1] deep-sea provinces;
Watling
et al
. 2013
) and the depth range to
1195 m
.
Distribution:
South Pacific and Indian Ocean, 320̄
1195 m
depth.
