简单描述
型态特徵 | 形态测量图
Light, gray brown color with the spots considerably faded or absent. Juveniles have caudal fin darkest along both spines and at the base, clear medially, a color pattern not found in any other members of the Hypostomus cochliodon group. Most similar to H. hondae and H. plecostomoides but differs by the general absence of spots on the caudal fin and/or caudal-fin spines (H. pagei may have very faint spots on the caudal-fin spines; some H. plecostomoides lack spots on the caudal-fin spines, but the spines are almost black instead of light gray-brown) and by having shorter pectoral-fin spine (reaching 0-1 plates beyond pelvic fin when depressed below the pelvic fin vs. 2-3 plates with the exception of one specimen of H. pagei that has pectoral-fin spines reaching two plates beyond the pelvic fin and the one specimen of H. plecostomoides examined from the Lago Valencia drainage that has pectoral-fin spines that do not reach beyond the pelvic fin) (Ref. 50589).
光, 灰色的褐色具有斑点非常地褪去或不存在。 稚鱼让尾鳍深色沿着两者的棘而在基底, 清澈的中间地，一个彩色斑纹不出现在 Hypostomus cochliodon 群的任何其他的成员。 非常类似 H. hondae 与 H. plecostomoides 但是不同之处为一般者在尾鳍上缺乏斑点及[或] 尾鳍棘 ( H. pagei 在尾鳍棘上可能有非常模糊的斑点; 一些 H. plecostomoides 在尾鳍棘上缺乏斑点，但是棘是幾乎黑色的取代淡灰色的-褐色) 而且藉著具有矮胸鰭棘 (達到 0-1個碟超過腹鰭當在腹鰭和 2-3個碟比較之下扁平的讓胸鰭棘達到的 H. pagei 的除了一件標本二個碟超過腹鰭與 H. plecostomoides 的這一件標本調查了有的從 Lago 瓦倫西亞流域不達到的胸鰭棘超過腹鰭).(參考文獻 50589)

Bayesian length-weight: a=0.01585 (0.00723 - 0.03476), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
