型态特徵 | 形态测量图
背棘 (总数): 2; 臀棘 0. Snout narrow, bluntly rounded, almost entirely bare, with a small inconspicuous scute at its tip. Suborbital ridge rounded and shallow in cross section, without scute-like scales. Cephalic pores of the lateralis system indistinct, but sensory papillae densely dispersed over the head. Pyloric caeca 25 to 37.
