簡短描述
型態特徵 | 形態測量圖
This species is distinguished from its congeners by having an anal fin; also by the following set of characters: the oral and preopercular canals share a short common branch off the infraorbital canal; long dorsal spine (DSA 28.4-31.0% BDL), longer than first dorsal fin, when depressed reaches beyond to origin of second dorsal fin; first dorsal fin is high (D1H 20.8-26.7% BDL) with a short base (D1B 10.3-12.5% BDL); long interdorsal space (IDS 8.1-10.2% BDL); long pectoral fin (P1A 40.0-43.5% BDL), when depressed reaches beyond origin of pelvic fin base; long pelvic claspers (CLT 17.5-17.7% BDL), bifurcate, divided at about distal 40.9-43.1% of its length; long dorsal caudal space (DCS 2.0-2.5% BDL); ventral caudal margin ending slightly posterior to dorsal caudal margin; coloration dark brown with ventral portion of the trunk and all fins slightly darker, without distinctive markings or mottling (Ref. 97389).
