Etymology: Plectranthias: Greek, plektron = anyhting to strike with, spur + Greek, anthias = a fish, Sparus aurata (Ref. 45335); clavatus: Named 'clavatus', meaning 'club', referring to the stripe on the lateral surface of the body that defines the species.
was
collected from 100–386 m depth in Sagami Bay and the
Hachijo-jima Island, Izu Islands, Japan, and Guam (Fig.
5). In addition, an individual was observed at 406 m
depth on the Shoho Sea Mount, Nishi-Shichito Ridge,
southern Japan (Koeda et al., 2021b). All individuals
were collected from over rocky substrate.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 17 - 18; Anal spines: 3; Anal soft rays: 7; Vertebrae: 26. This species is distinguished by the following set of characters: D X,17-18 (mode 17); pectoral-fin rays 13-14 (13), all are branched except for uppermost ray simple; principal caudal-fin rays 9 + 8; lateral line complete, pored scales 35-36 (35); scale rows above and below lateral line 5-5 and 16-17 (17), respectively; diagonal rows of large scales on cheek between eye and corner of preopercle 6-7 (6) ; circumpeduncular scales 15; rows of large predorsal scales ca. 8, single row of small scales extending to posterior two-thirds of interorbital area, tip not reaching line through posterior nostrils; body deep, depth at pelvic-fin origin 37.8-40.7 % (mean 39.1 %) of SL, greatest depth 39.6-42. 2 % (41.2 %) of SL; third dorsal-fin spine longest, its length 36.5-45.9 %
(41.9%) of body depth at pelvic-fin origin (BDP); anal-fin soft rays short, its longest ray length 47.9-59.1 % (53.5 %) of BDP; without scales on chin, branchiostegal membranes, infraorbital bones, maxilla, mandibles or snout; posterior margin of preopercle is serrated, ventral margin with 2 antrorse spines; short flaps at tips of second and third dorsal-fin spines. Colouration: three large orange-red saddles on dorsal edge of body; one orange-red stripe on posterior four-fifths of lateral body,saddles and stripe well-separated when fresh (Ref. 132445).
Cross section: compressed.
Collected over rocky substrate (Ref. 132445).
