背棘 (总数): 1; 背的软条 (总数): 7; 臀鳍软条: 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 与 C. weitzmani 以外，与它所有的同类区分了, 用它的彩色斑纹包含三大的, 黑色斑块, 第一个在头部上的 " 面具 ", 越过眼, 在背鳍的水平的躯干上的第二个, 与在脂鳍的水平的躯干上的第三个。 主要地进一步不同于 C. reynoldsi 藉由躯干斑块的发展; 而且从 C. weitzmani 藉由有一个暗色的鞍状斑在背部与脂鳍，第二个躯干斑块垂直地延伸从脂鳍基底到臀鳍基底之间, 與那在尾鰭中有四條深色又垂直的斑紋.(參考文獻 51470)
