型态特徵 | 形态测量图
This species is distinguished by the following characteristics: ochre to greyish brown or dark greyish disc and posterior pelvic lobes distinctly ornamented dorsally by many dark brown spots and dots and usually a few paired whitish spots in small and half-grown specimens, all often reduced in larger specimens to few pairs if larger symmetrically placed brown, pale edged spots, plus 1-2 pairs of pale spots or dots; disc inverse heart-shaped with snout tip with short, triangular projections; length of tail about 62% (mean) of TL; lateral folds only along the posterior half or 1/3 of tail length; hypocordal lobe on caudal fin; anterior pelvic lobes about 3/4 of posterior lobe length; no nasobasal fenestrae on cranium, with narrow anterior fontanelle and delicate, thin rostral shaft almost reaching rostral node (Ref. 75590).
