DISTINGUISHING
FEATURES
.— 1D II,10–11; P i19–i22;
V
8, rarely 9; inner GR-I 16–17 total, outer GR-II 16–17; scale rows below midbase 1D 7.5–9.0, below 2D 4.5–5.0; lateral line scales over distance equal to predorsal length 38–42. Snout length 25–27% HL; preoral length 18–19%; interorbital 29–32%; orbit 30–35%; suborbital 11–15%; orbit to preopercle 41–45%; upper jaw 42–47%; barbel 23–29%; outer gill slit 24–27%. Head and body relatively compressed; snout relatively short, high, forming obtuse angle viewed dorsally. Body scales covered with broad-based, triangular spinules in quincunx arrangement. Spinous ray of 1D usually less than HL, leading edge finely sawtoothed. Periproct occupying about half anterior space between
V
and A, close behind
V
bases, dermal window of light organ extends forward between
V
bases. Gill membranes narrowly united over isthmus and under midorbit. Color in preservative light to medium gray-brown overall, silvery over most of head, trunk, and anteriorly on sides of tail, but not over dorsum; jaws, gill membranes, and below suborbital ridge blackish; mouth pale, gill cavities blackish posteriorly; leading edge of snout blackish; 1D dusky, somewhat darker midlaterally;
V
blackish; P and A clear to dusky. Attains about
30 cm
TL.

DISTRIBUTION
.—
From
s.
Japan
to sw
Taiwan
[
SCS
], in
280–452 m
.
REMARKS
.— This is one of the most abundant species of macrourid in
Japan
, but it is not particularly common off
Taiwan
. The broadly triangular scale spinules on body scales are unique among the
Taiwan
members of this genus.
