Carpophilus truncatus Murray 1864, is a species of sap beetle which has been recorded from many countries worldwide, and has become recognised as an important pest of nuts. In this study, we present a re-description of C. truncatus including diagnostic photographic images of the adults and larvae, and demonstrate that Carpophilus jarijari Powell & Hamilton, 2019 is a junior subjective synonym of C. truncatus. Information about the species' distribution in Australia is updated. DNA barcode sequence data for C. truncatus is reviewed and augmented to enable differentiation from other morphologically similar Carpophilus species that are associated with nuts as hosts, including the cosmopolitan Carpophilus dimidiatus (Fabricius, 1792), for which C. truncatus has sometimes been misidentified. This analysis revealed that existing reference DNA sequences of "C. dimidiatus" consist of three highly genetically divergent lineages, representing three species: the cosmopolitan C. dimidiatus, the widespread C. truncatus, and a newly described species, Carpophilus imitatus sp. nov., known from south-eastern Asia and Australia.
Murray 1864 的 truncatus 是一种甲壳虫，已在世界许多国家被记录下来，并已被认为是坚果的重要害虫。在这项研究中，我们对 truncatus 进行了重新描述，包括成虫和幼虫的诊断照片，并证明 Carpophilus jarijari Powell & Hamilton, 2019 是 truncatus 的一个初级同物异名。更新了 truncatus 在澳大利亚的分布信息。审查并扩充了 truncatus 的 DNA 条码序列数据，以使其与其他形态相似的与坚果为宿主的 Carpophilus 物种区分开来，包括世界性的 Carpophilus dimidiatus (Fabricius, 1792)，有时 truncatus 会被错误识别为这种物种。该分析表明，现有的“C. dimidiatus”参考 DNA 序列由三个高度遗传上不同的谱系组成，代表三个物种：世界性的 C. dimidiatus、广泛分布的 C. truncatus 和一个新描述的物种，Carpophilus imitatus sp. nov.，已知分布于东南亚和澳大利亚。
