Conognatha (Pithiscus) coffeatus sp. nov. and Conognatha (Pithiscus) puris sp. nov., both from the Atlantic Rainforest (type locality: Itatiaia, Rio de Janeiro State, Brazil), are described and illustrated. They differ from each other mainly by the elytral colour pattern, presence of a short longitudinal groove between the vertex and the frons in C. (P.) puris sp. nov., and differences in frons shape, antennae sensory fields, pronotum and aedeagus. The distribution of C. (P.) gounellei is extended to the State of Minas Gerais, Brazil. A modified key to include the new species, as well as illustrations, are presented.
描述并图示了均来自大西洋雨林（模式产地：巴西里约热内卢州伊塔蒂亚伊）的新物种咖啡豆角胸肖叶甲（Conognatha (Pithiscus) coffeatus）和纯净角胸肖叶甲（Conognatha (Pithiscus) puris）。它们彼此的主要区别在于鞘翅颜色图案、纯净角胸肖叶甲头顶与额之间存在一条短纵沟，以及额的形状、触角感觉域、前胸背板和阳茎存在差异。将古内勒角胸肖叶甲（C. (P.) gounellei）的分布范围扩展到了巴西米纳斯吉拉斯州。还给出了包含新物种的修订检索表以及图示。
