簡短描述
型態特徵 | 形態測量圖
This species belong to the 'uarnacoides' complex, characterized by the following: lateral disc shape with pectoral fin apices broadly rounded rather than narrowly rounded or angular; color plain (usually uniform light to dark brown dorsally, and pale or whitish ventrally with or without a dark margin; a long and slender whiplike tail and platelike denticles in a broad dorsal band in adults. This species differs from H. hortlei in having a highly protrusible mouth and a pelvic girdle with prominent lateral prepelvic processes (Ref. 58327).
這種屬於被特徵為的 'uarnacoides' 複合體那在:之後 側面的體盤形狀用胸鰭頂點寬廣地圓的而不是狹窄地圓的或有角的; 彩色平原 (通常均勻的淡色到深色的褐色背面, 與灰白或微白色的腹地具有或沒有深色邊; 當成魚時的在一條寬的背部條紋中的一個長且細的鞭狀尾部與盤狀的細齒。 這種在有一個方面有別於 H. hortlei 能高度伸展的嘴，而且一個腰帶有突出的側面腹鰭前的突起。 (參考文獻 58327)
