The group is part of the taxonomically complex group of Neotropical cichlid fishes of the tribe Heroini. Many species groups and unplaced species of heroines are still left without a generic name following the revision of the genus . We describe here the group as a new genus, , and provide evidence for its monophyly based on phylogenetic analyses of morphological and mtDNA characters. is morphologically characterized by the lowest values in meristic characters among heroines and by three apomorphic characters in coloration pattern. In addition to the three described species of , our results of species delimitation based on a combination of tree- and character-based approaches identify seven putatively new species of . Several coding schemes of morphological characters are used to recover the intrageneric relationships within the genus, resulting in very similar topologies. Discovery of additional species within the genus is expected once material from the whole distribution area is studied.
该类群是丽鱼科英雄丽鱼族新热带丽鱼分类复杂类群的一部分。在该属修订后，许多英雄丽鱼的物种组和未归类物种仍没有属名。我们在此将该类群描述为一个新属，[属名]，并基于形态学和线粒体DNA特征的系统发育分析为其单系性提供证据。[属名]在形态上的特征是在英雄丽鱼中可数性状值最低，且在体色模式上有三个衍征性状。除了已描述的[属名]的三个物种外，我们基于树状和基于特征的方法相结合的物种界定结果确定了[属名]的七个可能的新物种。使用了几种形态特征编码方案来恢复该属内的属内关系，产生了非常相似的拓扑结构。一旦研究了整个分布区域的材料，预计该属内会发现更多物种。
