Two new species of the orphnine scarab beetle genus Madecorphnus Paulian, 1992 are described: M. heidiae Frolov Akhmetova, new species, and M. ranomafanensis Frolov Akhmetova, new species, from the Ranomafana National Park, Fianarantsoa Province, Eastern Madagascar. The new species can be easily distinguished by the endophallic armature consisting of more than 10 small and similar, conical tubercles in the former species and 3 long sclerites and 2 smaller indistinctly separated clusters of robust spinules in the later. Exact locality data are provided for the first time for two Triodontus Westwood, 1845, species: T. hildebrandtii (Fairmaire, 1883) was found in the northern Madagascar and is probably endemic to the Amber Mountain Range, T. fairmairei Frolov, Montreuil Akhmetova, 2016, was also found in the northern Madagascar: Antsiranana Province, Djangoa. The updated key to the Madecorphnus species is given.
描述了1992年孤儿金龟属（Madecorphnus Paulian）的两个新物种：来自马达加斯加东部菲亚纳兰楚阿省拉努马法纳国家公园的海德氏马德科尔夫金龟（Madecorphnus heidiae Frolov & Akhmetova）新物种和拉努马法纳马德科尔夫金龟（Madecorphnus ranomafanensis Frolov & Akhmetova）新物种。前一个新物种的内生殖器骨片由10多个小的、相似的圆锥形瘤组成，后一个新物种的内生殖器骨片由3个长的硬化体和2个较小的、紧密相连的粗壮小刺簇组成，据此可轻松区分这两个新物种。首次提供了1845年韦斯特伍德（Westwood）的两个三齿金龟属（Triodontus）物种的确切产地数据：希尔德布兰特氏三齿金龟（Triodontus hildebrandtii (Fairmaire, 1883)）在马达加斯加北部被发现，可能是琥珀山脉特有的物种；费尔迈雷氏三齿金龟（Triodontus fairmairei Frolov, Montreuil & Akhmetova, 2016）也在马达加斯加北部的安齐拉纳纳省让戈阿被发现。给出了更新后的马德科尔夫金龟属物种检索表。
