背棘 (總數): 1; 背的軟條 (總數): 7; 臀鰭軟條: 7. Distinguished from all its congeners, except Corydoras reynoldsi and C. weitzmani, by its color pattern consisting of three large, dark blotches, the first one "mask" on the head, across the eye, the second one on the trunk at the level of the dorsal fin, and the third one on the trunk at the level of the adipose fin. Differs further from C. reynoldsi mainly by the development of trunk blotches; and from C. weitzmani by the presence of a dusky saddle between the dorsal and adipose fin, the second trunk blotch extending vertically from the adipose-fin base to the anal-fin base, and the presence of four dark, vertical stripes in the caudal fin (Ref. 51470).
除了 Corydoras reynoldsi 與 C. weitzmani 以外,與它所有的同類區分了, 用它的彩色斑紋包含三大的, 黑色斑塊, 第一個在頭部上的 " 面具 ", 越過眼, 在背鰭的水平的軀幹上的第二個, 與在脂鰭的水平的軀幹上的第三個。 主要地進一步不同於 C. reynoldsi 藉由軀幹斑塊的發展; 而且從 C. weitzmani 藉由有一個暗色的鞍狀斑在背部與脂鰭,第二個軀幹斑塊垂直地延伸從脂鰭基底到臀鰭基底之間, 與那在尾鰭中有四條深色又垂直的斑紋.(參考文獻 51470)
