The taxonomy and systematics of the genus Digitonthophagus Balthasar (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) is revised. A detailed study of the male genitalia combined with external morphology suggests that the variability, previously recognized, for D. gazella is hiding a species complex within the Afrotropical region and the Arabian Peninsula. The current study recognizes 16 species; 13 from the Afrotropical region and Arabian Peninsula and three from the eastern portion of the Saharo-Arabian region and the continental Indomalayan region. Species are organized into six species groups based on the results of the morphology-based phylogenetic analysis. The following 12 species are described as new: D. aksumensis Génier new species; D. biflagellatus Génier new species; D. dilatatus Génier new species; D. eucatta Génier new species; D. falciger Génier new species; D. fimator Génier new species; D. namaquensis Génier new species; D. petilus Génier new species; D. sahelicus Moretto new species; D. uks Génier new species; D. ulcerosus Génier new species; and D. viridicollis Génier new species. In order to stabilize nomenclature, lectotypes are designated for Scarabaeus bonasus Fabricius, 1775; Scarabaeus catta Fabricius, 1787, and Onthophagus gazella lusinganus d'Orbigny. A neotype is designated for Scarabaeus dorcas Olivier, 1789 whose status and synonymy need to be altered in order to clarify the status of Scarabaeus gazella auctorum, the widely introduced species with economic importance. A naming scheme is presented for the sclerites of the internal sac. External and male genitalia are illustrated and distribution maps are provided for each species.
对 Digitonthophagus 巴尔塔萨尔属（鞘翅目：金龟科：金龟亚科：嗡蜣螂族）进行了分类学修订。对雄性生殖器与外部形态的详细研究表明，之前所认识到的 D. gazella 的变异性掩盖了一个分布于非洲热带地区和阿拉伯半岛的物种复合体。本研究确认了16个物种；其中13个来自非洲热带地区和阿拉伯半岛，3个来自撒哈拉 - 阿拉伯地区东部和大陆东洋区。根据基于形态学的系统发育分析结果，将这些物种分为六个物种组。以下12个物种被描述为新物种：阿克苏 Digitonthophagus aksumensis 热尼埃新物种；双鞭 Digitonthophagus biflagellatus 热尼埃新物种；膨大 Digitonthophagus dilatatus 热尼埃新物种；真猫 Digitonthophagus eucatta 热尼埃新物种；镰状 Digitonthophagus falciger 热尼埃新物种；挖掘 Digitonthophagus fimator 热尼埃新物种；纳马夸 Digitonthophagus namaquensis 热尼埃新物种；纤弱 Digitonthophagus petilus 热尼埃新物种；萨赫勒 Digitonthophagus sahelicus 莫雷托新物种；乌克斯 Digitonthophagus uks 热尼埃新物种；溃疡 Digitonthophagus ulcerosus 热尼埃新物种；绿颈 Digitonthophagus viridicollis 热尼埃新物种。为稳定命名法，为 1775 年的金龟属 Scarabaeus bonasus 法布尔、1
