簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 15 - 17; 背的軟條 (總數): 9-11; 臀棘 9-12; 臀鰭軟條: 8 - 9; 脊椎骨: 23. Diagnosis: 6-7 scale rows on cheeks; lateral line incomplete; caudal peduncle very short; caudal fin truncate (Ref. 57397). Usually a pored lateral line is lacking, but if present, only 4-6 scales of dorsally curving series pored; 16 principal caudal rays with 1 procurrent ray on each lobe; 1st pelvic ray with anterior and posterior branches projecting a little beyond fin membrane; caudal peduncle conspicuously short; 10 abdominal and 13 caudal vertebrae; 3 predorsal bones (supraneurals) in front of 1st dorsal pterygiophore (Ref. 81649).
Coloration: dull brown; head and sides with irregular dark brown/black spots sometimes forming a marbled pattern (Ref. 57397; 81649). Dark band from anterior base of dorsal fin through eye to snout tip; second dark band from ventrocaudal margin of eye ventrocaudally over cheek to ventral side of body anterior to pelvic fin base; distal parts of soft dorsal and anal fin, caudal and pectoral fins transparent; pelvics and spinous part and base of soft dorsal and anal fins brown (Ref. 81649). Fins seeming rayless when viewed form certain angles (Ref. 57397).
Occurs in rainforest areas (Ref. 6801). Maximum reported TL was 8.0 cm (Ref. 6801).
出現於雨林區域。 (參考文獻 6801)
