简单描述
型态特徵 | 形态测量图
This large species (to 122 cm TL) is distinguished by the following set of characters (based on the unique holotype specimen): strongly depressed and quadrangular disc with narrowly rounded apices, width 64% TL, 1.1 times its length; rather short tail, its length 0.8 in distance from snout tip to rear of cloaca, and width 1.8 times height at its midlength, 1.5 times at first dorsal-fin origin; pre-upper jaw length 18% TL, which is 2.3 times internasal width; ventral head length 32% TL; long and broad snout, length 4.0 times interorbital width, supported by slender flexible median cartilage; angle of snout 83°; narrow mouth 7% TL; orbit diameter 57% interorbital width; first dorsal-fin height is 1.7 in its base length; procaudal length 2.3 times first dorsal-fin base length, 4.8 times caudal-fin length; dorsal disc and almost entirely devoid of fine denticles; disc thornless, other than narrow alar thorn patches; tail with 16 (one lost) thorns in single median row; total pectoral radials 84-85; trunk centra 34; predorsal centra 105; total centra ca. 136; tooth rows in upper jaw 29; the skin is thin and almost entirely translucent white, no dark areas on body, sensory pores indistinct (not dark edged) (Ref. 110384).
