Aspidoras mephisto n. sp. is described from the Anésio-Russão cave system, upper Tocantins River basin, Goiás, Brazil. The species can be readily distinguished from its congeners by troglomorphic features and also by presenting the following combination of features: infraorbital 1 generally with well-developed ventral laminar; or moderately developed; poorly-developed serrations on posterior margin of pectoral spine; nuchal plate not externally visible; dorsal fin, even in conspicuously colored specimens, with only dark brown or black chromatophores concentrated on rays, forming spots in some specimens; membranes hyaline; or sparse dark brown or black chromatophores on membranes, not forming any conspicuous pattern; and inner laminar expansion of infraorbital 1 moderately developed. Information about its habitat, ecology, behaviour and conservation status are provided and also a brief description of the juvenile stage.
暗黑阿斯皮多鲇新种（Aspidoras mephisto n. sp.）是在巴西戈亚斯州托坎廷斯河上游流域的阿内西奥-鲁索洞穴系统中发现并描述的。该物种可通过洞穴形态特征以及以下特征组合轻松与同属其他物种区分开来：眶下骨1通常具有发育良好的腹侧薄片；或发育中等；胸鳍棘后缘锯齿发育不良；颈板外部不可见；背鳍，即使在颜色明显的标本中，也只有深棕色或黑色色素细胞集中在鳍条上，在一些标本中形成斑点；鳍膜透明；或鳍膜上有稀疏的深棕色或黑色色素细胞，不形成任何明显图案；眶下骨1的内侧薄片扩张发育中等。文中提供了关于其栖息地、生态、行为和保护状况的信息，以及幼鱼阶段的简要描述。
