A new long-snouted Corydoras species is described from two tributaries of the río Manuripe and a tributary of the río Madre de Dios, rio Madeira basin, Peru. Corydoras fulleri can be distinguished from its congeners by having the following features: (a) branch of the temporal sensory canal at sphenotic, which gives rise to the supraorbital canal, with two pores; (b) upper tooth plate of branchial arch with three series of teeth; (c) area at the corner of the mouth, ventral to the maxillary barbel, with a small fleshy flap; (d) two moderate-sized dark-brown or black blotches on caudal-fin base, one on its lateral portion and another one on its dorsal portion, blotches variably diffuse and/or fused with each other; (e) absence of a dark-brown or black stripe transversally crossing the orbit; (f) a longitudinal dark-brown or black stripe on the postdorsal region of flank midline, variably fused with the lateral peduncular blotch, some specimens with slender, longitudinally elongated, dark-brown or black blotch on flank midline, forming a dash-like marking, stripe or dash-like blotch diffuse in some specimens; and (g) region around dorsal-fin origin generally lacking dark brown or black blotch, or displaying diffuse blotch.
一种新的长吻棘茄鱼物种描述自秘鲁马德雷德迪奥斯河流域的马努里佩河的两条支流和马德拉河的一条支流。Corydoras fulleri 可通过以下特征与其近缘种区分开来：(a) 发自 sphenotic 的颞感觉管分支，产生眶上管，有两个孔；(b) 鳃弓上的齿板有三排牙齿；(c) 口角处，在颌须的腹侧，有一个小的肉质瓣；(d) 尾鳍基部有两个中等大小的深褐色或黑色斑点，一个在其侧面，另一个在其背面，斑点可变弥散和/或融合在一起；(e) 没有穿过眼眶的深褐色或黑色条纹；(f) 侧线中线背部后的后背部有一条纵向的深褐色或黑色条纹，与侧柄斑可变融合，一些标本在侧线中线有细长的、纵向拉长的深褐色或黑色斑点，形成点状标记、条纹或点状斑点，在一些标本中扩散；(g) 背鳍起点周围的区域通常没有深褐色或黑色斑点，或显示弥散的斑点。
