Genus
Calcigorgia
Broch, 1935
Diagnosis
Acanthogorgiid gorgonians whose sclerites are not individually conspicuous and not regularly arranged in the polyp. Sclerites are spindles, capstans, ovals, and clubs with warty, leafy, or serrated heads.
Remarks
The diagnosis given above combines those provided by
Broch (1935)
and
Bayer (1981)
, and adds the cases when clubs with leafy or serrated (dentate) heads are present. Leafy clubs were shown for
Calcigorgia matua
,
C. herba
sp. nov.
and
С.
lukini
sp. nov.
Clubs with serrated heads were found in
C. japonica
and in some specimens of
Calcigorgia
from
Matsumoto
et al.
(2019)
.
Matsumoto
et al.
(2019)
also gave a diagnosis of the genus, but they wrongly noted that “tentacular sclerites are scales or absent; polyp and coenenchymal sclerites in the form of stout tuberculate spindles” (
Matsumoto
et al.
2019: 2–3
).
Calcigorgia spiculifera
, the
type
of the genus, has not only scales but also clubs and spindles in the tentacles. Its polyp body and coenenchyme with capstans and ovals (
Broch 1935: 22–25
, fig. 14;
Table 1
of the present paper). Additionally, various sclerite
types
besides the scales were documented in tentacles and other parts of colonies of a range of
Calcigorgia
representatives, including those described in
Matsumoto
et al.
2019
(
Table 1
of the present contribution).
