形態学 | 形態計測学
背面の脊椎 (合計): 7; 背鰭 (合計): 9; 肛門の骨 1; 臀鰭: 10. This species is distinguished by the following set of characters: D2 9, first dorsal fin pointed with elongate fourth spine in male; pectoral-fin rays 16; premaxilla 46-50 tricuspid teeth; dentary 4 (male) or 1 (female) symphyseal teeth and 40-46 unicuspid horizontal teeth in 2.7-3.6 cm SL; scales in longitudinal row 30-32; nape and posterior half of occipital region with cycloid scales; males without white patch behind pectoral-fin base and a broad black band along distal margin of second dorsal fin, the lateral side of body and dorsal and caudal fins often tinged with vivid orange; females with 11 or 12 dusky transverse bars laterally on trunk and tail, intersecting with the mid-lateral longitudinal band and has several conspicuous black spots on each of the spines and soft rays on the first and second dorsal, and caudal fins; anal fin lacking remarkable marking; pectoral-fin rays with 2-5 and 1-4 black spots, respectively, for male and female (Ref. 95104).
The species was observed in a small pool less than 1 m deep and a rapid just below the pool, located 1.5 km from the stream mouth, no major barrier to upstream migration between the stream mouth and this site. The individuals were often shoaled with the abundant S. percnopterygionus and observed scratching on the rock surface for feeding with them. Single individuals of S. atropurpureus and S. multisquamus were also observed at the same site. Other abundant fishes found on the site were amphidromous gobies, such as Sicyopterus japonicus (Tanaka 1909), Awaous melanocephalus (Bleeker 1849), Rhinogobius nagoyae Jordan and Seale 1906, and Tridentiger kuroiwae Jordan and Tanaka 1927, amphidromous pipefish, Microphis leiaspis (Bleeker 1854), and catadromous flagtail, Kuhlia marginata (Cuvier 1829) (Ref. 95104).
