A new species of the orphnine scarab beetle genus Madecorphnus Paulian, 1992, Madecorphnus grebennikovi Frolov, Akhmetova Vishnevskaya, new species, is described from the Marojejy National Park, Sava Region, northeastern Madagascar. The new species can be distinguished from the congeners by the parameres narrowly rounded in lateral view and having a small but distinct lateral teeth, and by the endophallic armature consisting of 1) a long straight sclerite with attached to its end a 2/3 shorted, somewhat curved sclerite, 2) separate smaller, elongate sclerite, and 3) a rather large area of microspinules. The 811 bp long fragment of the mitochondrial gene COI (DNA barcode) is provided as a part of the diagnosis of the new species. An updated key to the Madecorphnus species is given.
1992年，奥菲尼金龟甲属（Madecorphnus Paulian）新增了一个物种，即马岛奥菲尼金龟（Madecorphnus grebennikovi Frolov, Akhmetova Vishnevskaya），新物种发现于马达加斯加东北部萨瓦地区的马罗杰伊国家公园。该新物种可通过以下特征与同属其他物种区分开来：阳茎侧叶在侧视图中呈窄圆形，有小而明显的侧齿；内阳茎骨片包括：1）一根长直骨片，其末端附着一根短约2/3、略弯曲的骨片；2）单独的较小的细长骨片；3）相当大的微刺区域。作为新物种鉴定的一部分，提供了线粒体基因COI 811 bp长的片段（DNA条形码）。文中还给出了马岛奥菲尼金龟属物种的最新检索表。
