Diagnosis. A species of Hapalogenys with the following combination of characters: fleshy lower lip with dense cluster of short papillae and barbels anteriorly, 10 pores on and behind chin, 4 anterioriormost pairs hidden by papillae (figs 3A–B), slightly scaly posteriorly (on posterior abdominal part of angular of lower jaws, fig. 3B); small scales on maxilla (fig. 3A); 5–7 alternating whitish and dark-brown bands on head and body, 1st (often indistinct) from just before eye to posterior of lower jaw, 2nd somewhat oblique, becoming wider posteriorly, from nape to between eye and pelvic-fin base, 3rd from base of 2nd and 3rd dorsal-fin spines to just behind pelvic-fin base; 4th from 7th and 8th dorsal-fin spine base to just before 1st anal-fin spine, 5th from 2nd and 3rd dorsal-fin soft ray base to anterior of anal-fin soft ray base, 6th on caudal peduncle, 7th (often indistinct) on caudal-fin base; soft rayed portions of dorsal and anal fins somewhat rounded posteriorly and slightly angulated posteriorly, respectively (fig. 1A), spinous dorsal-fin and analfin (until 1st anal-fin ray) membranes dense black; membrane of soft dorsal- anal- (especially in juveniles and young) and caudal-fins somewhat yellowish in fresh specimens, a dense black margin posteriorly, about same width as pupil diameter (juveniles) or half of this width (adults) (fig. 1A); pelvic-fin tip not reaching to base of 1st anal-fin spine when depressed (fig. 1A); 44−47 (but rarely 43 or 48) pored lateral-line scales; procumbentspine-likeprocess (exposedtipof 1stpterygiophore) at origin of dorsal fin usually covered by predorsal scales.

Description. Counts and proportional measurements as percentage of SL for the neotype and other specimens are given in Table 1. Data for the neotype are presented first, followed by non-type material (if different) in parentheses. Characters given in the diagnosis are not repeated.

Body deep, 49% of SL (47–57% of SL), relatively compressed, covered with ctenoid scales, ctenii free on posterior margin of exposed area; lateral line continuous until on hypural plate; orbit diameter distinctly larger than interorbital space; suborbital depth distinctly less than eye diameter; head covered with scales, extending almost to anterior nostrils; lips, chin and ventral part of urohyal naked; cheek and opercle fully scaled; jaws with bands of pointed conical teeth, outermost teeth generally enlarged, but not forming canines; teeth absent on vomer and palatines; preopercle serrate; upper opercle with 2 short spines posteriorly; single notched dorsal fin; 3rd dorsalfin spine and 2nd dorsal-fin ray longest; 1st dorsal- and anal-fin soft rays not strongly bifurcated; 1st anal-fin spine short, 2nd longest, clearly longer than 3rd; dorsal and anal fins with high scaly sheath; caudal fin generally rounded.

Live colouration. Based on photograph of MUFS 12258 (fig. 1A), neotype, 185 mm SL and MUFS 8422, 113 mm SL: head and body generally dark brownish, with 7 alternating whitish and dark brown bands (see Diagnosis); iris black; lips, lower part of cheek, preopercle and interopercle pale brownish .

Preserved colouration. Based on the neotype and non-type specimens: head and body generally similar to live colouration.

Distribution. Hapalogenys analis is currently known from the East Asian Shelf to the Sea of Japan and Pacific coast of southern Japan (except Ryukyu and Ogasawara Is.), including the western part of Taiwan and South China Sea (fig. 5). Lim, 1994 questionably reported H. analis from Singapore (3 collected specimens in total) (K. K. P. Lim, ZRC, pers. comm.).

Ecological note. Most specimens of Hapalogenys analis have been collected by bottom trawl in depths less than 100 m. Smaller specimens (<about 100 mm SL) have been collected by set nets in depths of 20– 50 m.

Remarks. The date of publication of Hapalogenys mucronatus Eydoux and Souleyet (as 1841 on cover, but presumably 1850) and status of that species as a junior synonym of H. analis Richardson, 1845 as given by Bauchot et al., 1982, 1983, Lim, 1994, and Iwatsuki et al., 2000a is followed here. The type specimens of H. analis Richardson, 1845 are lost (J. Maclaine, BMNH, pers. comm.) and a neotype ( MUFS 12258, 185 mm SL) of the species is herein designated in order to avoid confusion.
