Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 6; Vertebrae: 24. This species is distinguished by the following characters: pored lateral line scales 34-37 (modally 36); scale rows between lateral line and base of 6th dorsal-fin spine 3 (two full-sized plus a dorsalmost half-sized scales); developed gill rakers 1-2 + 7-8 (modally 2 + 7); cheek scale rows 4-7 (modally 5); dentary surface of the lower jaw naked; interorbital region with a one row of cycloid scales extending to or slightly beyond the mid-orbit level; outermost row of teeth of the upper jaw are enlarged, antrorse and caniniform; outermost row of teeth of the lower jaw at the lateral side near symphysis with ca. 3-4 enlarged antrorse canines, the innermost row of teeth enlarged and caniniform; penultimate and the last dorsal- and anal-fin rays in adult are not elongated. Colouration: a red ocellus on opercular membrane between the spines; soft dorsal fin with series of large yellow spots; anal fin with a yellow margin; caudal fin with yellow spots along basal-half median fin rays; with a faint and discontinuous stripe formed by clusters of melanophores along the mid-lateral body when preserved (Ref, 127472).
a relatively shallow water species compare to its congeners. It was trawled
from seamount and bands at depth 150–160 m in its type locality (Lee et al., 2019). In Taiwan, it is captured by
bottom-trawl off southwestern Taiwan, the depth of the trawl operation is assumed to be rubble sandy bottom
(topology of seafloor unknown) at depth ca. 100 m, judging from others by-catch species [e.g., Neomerinthe erostris
(Alcock, 1896), Scorpaena miostoma Günther, 1877] (Ref. 127472)
