Carpocorini are the most diverse tribe within Pentatominae, comprising about 100 genera and 500 species, with the highest diversity found in the Neotropics. Within Carpocorini, some groups of genera have been, formally or informally, proposed based on morphological similarities and taxonomic history. The Euschistus group was informally proposed and comprises 20 genera, including Euschistus Dallas, 1851 and Dichelops Spinola, 1837. Both of these genera had their monophyly under dispute recently. Dichelops, which includes the species commonly known as the green‐belly stink bug, comprises 16 species in three subgenera, with an exclusively Neotropical distribution. The genus was revised recently, and for each subgenus, a set of distinct morphological characters was listed, which allow their precise identification. We tested the monophyly of the Euschistus group and of Dichelops under parsimony criteria using discrete and continuous characters and two‐character weighting methods. The Euschistus group was paraphyletic, and Dichelops was polyphyletic in every analysis, and the taxonomic characters formerly proposed as diagnostic for the genus and its subgenera were homoplastic. On the basis of the phylogenetic result, we propose the erection of Diceraeus Dallas, 1851, stat. rev. to the status of genus and Dichelops comprising two subgenera, the nominal and Prodichelops Grazia, 1978. This decision has implications for applied entomology, because species of Diceraeus are important crop pests in the Neotropics.

Euschistus群体（半翅目：Pentatomidae）的系统发育分析表明，Dichelops Spinola的多重性，1837年，Diceraeus Dallas的勃起，1851年。转速

Carpocorini是五角蕨科中种类最多的部落，约有100属500种，在新热带地区具有最高的多样性。在Carpocorini中，根据形态相似性和分类学历史，正式或非正式地提出了一些属。在美洲蝽组非正式提议，并包括20个属，其中包括美洲蝽达拉斯，1851年和Dichelops斯皮诺拉，1837年这两个属有争议的单系最近。Dichelops包括通常称为绿腹臭虫的物种，包括三个亚属中的16种，仅具有新热带分布。该属最近进行了修订，并且为每个亚属列出了一组不同的形态特征，从而可以对其进行精确识别。我们使用离散和连续字符以及两个字符的加权方法，在简约标准下测试了Euschistus组和Dichelops的单字。在美洲蝽组并系和Dichelops在每个分析中都是多系的，以前建议作为该属及其亚属诊断的分类学特征是同型的。根据系统发育结果，我们建议竖立Diceraeus Dallas，1851，stat。转速 属于两个亚属的属和双足纲属，名义上的和前足纲属格拉齐亚属（Prodichelops Grazia），1978年。这一决定对应用昆虫学具有重要意义，因为双足纲的物种是新热带地区的重要农作物害虫。
