Body oblong, moderately compressed posteriorly. Body depth at pelvic-fin origin subequal to depth at anal-fin origin. Caudal peduncle moderately short, depth greater than length. Head moderately large. Dorsal profile of snout moderately rounded. Fleshy anterior edge of head slightly pointed, compressed. Snout long. Orbit large. Pupil diameter subequal to half orbit diameter. Interorbital space convex. Single large sheath of scales on anterodorsal margin of orbit. Cheek region naked. Mouth small, slightly obliquely angled backwards, ca. 15° to horizontal axis of head and body. Lips thick, inwardly curled dorsally, progressively more curled posteriorly. Jaw teeth affixed to outer edge of bony ridge. Two pairs of strongly curved canine teeth at front of each jaw; 11 small thickened teeth posteriorly on each bony plate behind upper-jaw canine teeth; 11 (12) small thickened teeth (length one-third of canine teeth) posteriorly on each bony plate behind lower-jaw canine teeth; numerous small teeth rows follow outer dentition ridge. Tongue short, slender, rounded, upper surface covered with small papillae. Gill opening wide. Gill rakers thickened, short, longest on first arch about one-half length of longest gill filament. Preopercular margin smooth, extending beyond vertical through ventral margin of orbit. Anterior nostril a tiny aperture; posterior nostril short, slightly oblique.

Body, including caudal peduncle, covered with cycloid scales. Scale diameter at mid-body nearly equal to eye diameter; axillary scale length half that of mid-body scales. Pectoral-fin base with 5 cycloid scale rows. Caudal-fin base with 4.5 scale rows. Scales above lateral-line scales 4; scales below lateral-line scales 9. Lateral line interrupted; pored lateral-line scales 20 + 5, with single tube; anterior series following dorsal contour of body; posterior series running mid-laterally on posterior region of body; 2 scale rows between last pored-scale of anterior series and first pored-scale of posterior series; 3 scale rows below first pored-scale of posterior series.
Origin of first dorsal-fin spine posterior to vertical through posterior margin of orbit; distance between vertical through posterior margin of orbit and dorsal-fin origin greater than orbit diameter. Dorsal spinous portion lower than soft rayed portion; first spine thin, fleshy, flexible; first dorsal-fin spine longer than second spine. Second dorsal-fin spine inflexible (tip flexible in <100 mm SL). Length between first- and second dorsal-fin spine bases less than that between second- and third dorsal-fin spine bases. Origin of anal-fin spine slightly posterior to vertical through last dorsal-fin spine base; end of anal-fin base slightly beyond vertical through 12th dorsal-fin soft ray base. All dorsal- and anal-fin soft rays branched. Pectoral fin long, rounded, posterior margin just reaching to vertical through last dorsal-fin spine base, first and second pectoral-fin soft rays unbranched, remainder branched. Pelvic fin long; posterior margin of first soft ray beyond anus; all soft rays branched.
Color of holotype when fresh, based on color photograph (Fig. 1A). Body yellow, dorsal region bright orange, ventral region white; mid-body bright orange. Posterior margin of dorsal scales edged bright red. Dorsal-fin spinous portion bright yellow, membrane between first- and second dorsal-fin spines black; dorsal-fin soft rayed portion white basally, yellow distally. Anal fin white basally, yellow distally. Pectoral fin bright orange. Pelvic fin translucent. Caudal fin bright yellow. Orbit pale red, posterodorsal margin of orbit black. Pupil black. Lips bright orange.
Coloration of paratype when fresh, based on color photograph (Fig. 1B). Body pink dorsally, white ventrally; mid-body bright yellow. Posterior margin of dorsal scales edged bright red. Dorsal-fin spinous portion bright pink, soft rayed portion translucent. Anal fin white basally, translucent distally. Pectoral fin bright orange. Pelvic fin translucent. Caudal fin pale pink basally, translucent distally. Orbit pale red, with black posterodorsal margin. Pupil black. Lips pale pink.
Coloration of preserved specimens (Fig. 2). Body brown. Posterodorsal margin of orbit black. First two dorsalfin membranes black (holotype). Axil of pectoral fin black. All fins translucent.
Distribution. Currently known only from Yoron Island, Kagoshima, Japan and Panay Island, the Philippines (Fig. 3).
Etymology. The specific name for the new species is from the Latin “compressa” meaning “compressed”, referring to the compressed body.
