A species of Parascorpaena with the following characters: pectoral-fin rays 15–17 (usually 15 or 16); pored lateral-line scales 20–22 (mode 21); scale rows in longitudinal series 40–48 (41); scale rows above lateral line 5–8 (7); scale rows below lateral line 10–12 (12); scale rows between sixth dorsal-fin spine base and lateral line 5 or 6 (6); scale rows between last dorsal-fin spine base and lateral line 5 or 6 (5); total gill rakers 12–14 (12); two suborbital ridges, each with one spine; origin of first suborbital ridge posterior to origin of second ridge; interorbital ridges well developed posteriorly from middle of eye, forming a broad loop on rear end, enclosed concavity relatively shallow; occipital pit not developed, almost flat; no scales along dorsal- and anal-fin soft ray bases; black botch on spinous portion of dorsal fin in males, usually found along 7 th – 10 th spines. Description. Measurements of examined specimens, expressed as percentages of SL and HL, provided in Table 2. Body size small, compressed, with numerous widely scattered papillae; body depth greatest at pelvic-fin spine base. Lateral line complete, pored lateral-line scales continuing onto caudal-fin base (except in small specimens). Head size moderate, length less than half SL, with scattered papillae. Snout moderately blunt; dorsal profile steep. Eyes large, diameter slightly greater than snout length. Mouth large, maxilla extending just below posterior margin of eye. Four prominent pairs of mandibular pores on dentary, first pore positioned just behind tip of lower jaw, second along anterior lacrimal spine, third along posterior lacrimal spine, and fourth behind posterior lacrimal spine (before posterior end of maxilla). Teeth on upper jaw villiform; teeth on lower jaw varying among specimens, from entirely villiform to villiform with enlarged or canine-like teeth on frontal area; teeth on palatines small, villiform, in bands; teeth on vomerine villiform, in V-shaped patch. Body entirely covered with cycloid scales (rarely with weak ctenii); body scales not extending to dorsal- and anal-fin soft ray membranes; head mostly naked, a few, small scales behind posterior margin of eye, along posterior end of operculum, and just behind opercular spines; dentary smooth, naked. Dorsal-fin spines usually 12 (rarely 13) connected to soft rays; fourth or fifth spine longest; sixth to 11 th spine gradually decreasing in size; 12 th spine elongated, followed by nine (rarely 8) branched soft rays; second dorsal-fin soft ray usually longest; 7 th – 10 th dorsal spines bearing black blotch in male specimens. Anal-fin spines three, second spine longest; five branched soft rays. Bases of both dorsal- and anal-fin soft rays without scales. Pectoral-fin rays usually 15 or 16 (rarely 17); first (uppermost) ray simple, unbranched; second to fifth or sixth ray branched; lower rays thickened, unbranched; tips of fins reaching beyond origin of anal-fin spine. All pectoral-fin rays in small specimens (e. g., <20.0 mm SL) unbranched. Pelvic-fin length variable, not or just reaching anal-fin spine base. Nasal spines positioned bilaterally on nasal ridge, extending slightly beyond rim. Preocular spine relatively thick, with broad base, located anteriorly within orbital region. Interorbital ridge originating either from above anterior half of eye, or along preocular spine base, extending beyond posterior eye margin; rear end of ridge forming a broad, very shallow interorbital loop. Occipital pit indistinct, almost flat. Supraocular and postocular spines situated above orbital region, close to one another. Supraocular spines each occasionally bearing a single, variably sized tentacle, sometimes small but usually longer than eye diameter. Tympanic spines simple, just behind postocular spine, usually separated by distance greater than that between parietal and nuchal spines. Parietal and nuchal spines simple, close to one another; parietal spine originating posterior to origin of pterotic spine; nuchal spine originating just behind parietal spine. Sphenotic spine just behind posterior margin of eye, small, usually as unevenly sized pair (rarely single). Pterotic spine simple, attached to skin, situated just behind sphenotic spine. Upper and lower post-temporal spines well-developed, upper spine shorter than and positioned just above lower spine, lower spine situated between pterotic and supracleithral spines. Suborbital with two distinct ridges, a suborbital spine on each ridge. Lacrimal bone dorsally with two distinct ridges; anterior lacrimal ridge located before anterior eye margin, longer than posterior lacrimal ridge; posterior ridge located just behind origin of first suborbital ridge (just below ventral eye margin). Anterior and posterior lacrimal spines located along ventral region of lacrimal bone, simple with no additional spinous points; anterior lacrimal spine prominently antrorse, tip not extending beyond lower lip; posterior lacrimal spine distinctly anteriorly oriented in larger specimens (> 24.5 mm SL), ventrally oriented with forward curvature in smaller specimens to ~ 20 mm SL, postero-ventrally oriented in sp
