Remarks.
The
holotype
specimen of
Clibanarius sachalinicusKobjakova, 1955
(
Figs. 3
,
4
) is morphologically identical to
Clibanarius virescens
(Krauss, 1843)
. Thus,
C. sachalinicus
should be considered as a junior synonym of
C. virescens
.
It was also concluded by
McLaughlin (1996)
than
type
specimens of
Calcinus astathes
Stebbing, 1924
(also usually reported as a junior synonym of
C. virescens
) housed in The Natural History Museum (London), were not conspecific with truly
C. virescens
and indicated
Clibanarius astathes
as a valid species (
Hogarth
et al
, 1998
).
Distribution.
Widely distributed tropical Indo-Pacific species known from S. Arabia, South and East Africa to
Japan
, the
Ellice Islands
,
Guam
and
Fiji
(
Haig& Ball 1988
,
Lewinsohn 1982
); reported from Korean waters (Jung & Kim, 2015).The presence of
C. virescens
, actually subtropical or even tropical species, in sublittoral of cold water Mordvinova Bay of Sakhalin
Island
(46°50′4″
N 143°19′
18″E) is questionable. The measured average summer temperature (May–September) of surface water is about 5–9C, then the Bay is covered with ice during the winter time; water temperature on the depth 40–50 meters is more constant being about 3–5C. Probably, in the case with locality of
holotype
of
C. sachalinicus
it was a mislabeling of the sample because Zinaida I. Kobjakova also worked in
Japan
and
Korea
and possibly had in her collections material on shallow water hermit crabs from these localities. The tropical hermit crab
C. virescens
can actually present in north-eastern part of the Sea of
Japan
in the areas (for example, around north Hokkaido) influenced by Kuroshio Current that usually brings tropical species onto colder waters (for example,
Marin
et al
, 2012a
,
b
), but Mordvinova Bay has never been influenced by Kuroshio Current situated quite far from its to northern stream.
