Etymology: Corydoras: Greek, kory = helmet + greek, doras = skin (Ref. 45335); diphyes: Specific name from Greek 'diphyes', meaning of double nature, in reference to the unique variation in color patterns expressed in this species, striped and blotchy.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 18 - 19. Relatively low scute numbers (dorsal/ventral row, 23-24/20-21, pre-adipose scutes 2-4, usually 3), series of 4-6 distinct spots or a continuous midlateral band along the middle of the side instead of 2-3 large dark blotches; dorsal and pectoral fins not elongated in either sex; distinct stripes in dorsal and caudal fins (Ref. 52874).
相當低的鱗甲數字 (背部的/腹的列,23-24/20-21, 前脂肪的鱗甲 2-4, 通常 3), 數列 4-6個明顯的斑點或一條連續的側面中央的條紋沿著側邊的中央取代 2-3個大的黑色斑塊; 背部的與胸鰭在任一性別方面不延長; 在背鰭與尾鰭鰭明顯的斑紋。 (參考文獻 52874)
描述:
Facultative air-breathing (Ref. 126274); Usually occurs in areas with sandy bottom, bank vegetation entering water or with marginal aquatic plants, dark, clear or slightly turbid water and limited associated fauna (Ref. 52874). Mimicked by Otocinclus mimulus; (Ref. 52874). Mimicry is unusual because the two species occupy different microhabitats and it is hypothesized to operate with a primarily visual predator moving between the microhabitats, tentatively identified as the cichlid Crenicichla lepidota (Ref. 52874).
通常出現於區域中且底部為沙地的地方, 河岸植被進入水或具有邊緣的水生植物, 深色的﹐清澈的或些微混濁的水與有限制的相連動物相.(參考文獻 52874) 被 Otocinclus mimulus 擬態; (參考文獻 52874). 因為兩者種佔領不同的小環境，而且它被假定操作，所以擬態是罕見的具有一個被暫時地鑑定為麗魚科的 Crenicichla lepidota 的在小環境之間移動的主要視覺的掠食者.(參考文獻 52874)
