Dark brown dorsal and ventral surfaces; ventral entirely dark. Snout elongated, usually more than 1/3 in disc length (preocular snout region 40% in disc length in lectotype). Disc oval, longer than wide. Dorsal fins with long, fleshy bases which are much longer than height of the fin (dorsal fin length 50-55% of fin height). Origin of first dorsal well anterior to posterior tip of pelvic fins, close to mid pelvic length; dorsal fins close together, interdorsal space less than length of dorsal bases. Distance between second dorsal and caudal fins much smaller than length of base of second dorsal fin. Caudal fin extremely elongated, reaching almost 1/2 tail length as measured from posterior tips of pelvic fins; caudal fin length 40.4% of distance between cloaca and caudal fin tip (Ref. 48493).
Body shape (shape guide): other.
深褐色的背面与腹面; 腹的完全深色。 吻延长, 通常超过 1/3 在体盘长度中.(preocular 吻区域 40% 在选方式的体盘长度中) 体盘椭圆形, 长度超过宽的。 背鳍具有长又肉质的基底那是远长过鳍的高度.(背鳍长度 50-55% 的鳍高度) 第一背鳍的起源在腹鳍的后顶端前, 接近腹鳍长度的中央; 背鳍靠拢在一起, 间背片的间隙少于背鳍基底长。 第二背鳍与尾鳍之间的距离远小于第二背鳍基底的长度。 尾鳍非常地延长, 几乎达到 1/2 尾部长度当从腹鳍的顶端后缘测量; 尾鳍长度 40.4% 的泄殖腔与尾鳍顶端之间的距离.(参考文献 48493)

A benthic species on continental slope. Probably suction feeds on bottom-dwelling invertebrates based on its oral morphology. Biology little known. Maturity size uncertain, probably close to 18 cm TL in males (Ref. 114953).
