REMARKS
.—
Coelorinchus kishinouyei
was strangely not recorded by Okamura and Kitajima (1984) from the
Okinawa
Trough, where it would be expected owing to its presence in s.
Japan
and
Taiwan
. In this regard, the distribution is similar to that of
C. hubbsi
.
It is relatively abundant in landings at Da-xi in ne.
Taiwan
. This highly distinctive species is closely similar to
C. jordani
, which has a much smaller pectoral blotch and a longer light organ that extends well forward of the pelvic bases and onto the chest. The
Taiwan
specimens of
C. kishinouyei
appeared to have a slightly longer snout, smaller orbit, darker overall coloration with little or no silvery, with anal fin black overall, and blotch above pectoral fin more obscure and lacking pale outer ring (i.e., not ocellated).
