The Carpocorini are distributed worldwide, and it is one of the most speciose tribes within the Pentatomidae with 127 genera and more than 500 valid species. Recently, Adustonotus Bianchi was described to contain eight species formerly placed within Euschistus Dallas. Among them, Adustonotus grandis (Rolston) and Adustonotus latus (Dallas) are remarkable for their large size. Herein, the phylogenetic position of a new taxon is inferred by a total evidence analysis based on 85 morphological characters and four molecular markers. Adustonotus graziae sp. nov. is described, and is recovered in a polytomic lineage, including A. grandis and A. latus. These species share a solid combination of features that enable them to be separated from the other Adustonotus species (e.g., large size, the humeral angles spatulate and exceptionally produced, and the capsula seminalis shortened). Illustrations of external and internal genitalia, and a distributional map are provided.
梨象族分布于世界各地，是Pentatomidae 科中物种最丰富的部落之一，拥有 127 个属和 500 多种有效物种。最近，Adustonotus Bianchi 被描述为包含以前归入 Euschistus Dallas 的 8 个物种。其中，Adustonotus grandis (Rolston) 和 Adustonotus latus (Dallas) 因其体型较大而引人注目。在此，通过基于 85 个形态特征和四个分子标记的综合证据分析，推断出一个新分类单元的系统发育位置。描述了一个新种，Adustonotus graziae sp. nov.，并在一个多分支谱系中恢复，包括 A. grandis 和 A. latus。这些物种具有一些稳定的特征组合，使它们能够与其他 Adustonotus 物种区分开来（例如，体型较大，肩角呈桨状且异常突出，以及精囊缩短）。提供了外部和内部生殖器的插图以及分布图。
