Current status.
Valid.
Remarks.
The specimens upon which
Halecium flabellatum
is based were sent to
Fraser (1935b)
for identification from the collection of Emperor Hirohito of
Japan
.
No
name-bearing
type
of the species was designated by him. Four samples of
H. flabellatum
are recorded in the Fraser Hydroid Collection at the RBCM. Two of them, listed above and both labelled “
type
” in what appears to be Fraser’s handwriting, are
syntypes
. Both are now dry. The specimens, with a single colony in each sample, were examined without being removed from their vials by us during this study. Although desiccated, major characters of the species as illustrated by
Fraser (1935b)
and
Hirohito (1995)
are still recognizable. In being the only
syntypes
, and in the expectation that at least partial rehydration might be possible, we have selected the female colony (BCPM 976-00476-001) as the
lectotype
. The male colony (BCPM 976-00476-002) is a
paralectotype
. The other two (976-00477-001: Sagami Bay, female; BCPM 976-00477-002: Sagami Bay, male) were not from the
type
locality and are not part of the
syntype
series. Specimens of
H. flabellatum
in NSMT collections (NSMT-HyR 1389:
Japan
, off Jôgashima,
108 m
,
19 August 1936
), recorded by
Hirohito (1995)
, are also not
syntypes
.
Halecium flabellatum
was regarded as valid by
Hirohito (1995)
, a conclusion upheld in WoRMS.
