Deltochilum Eschscholtz， 1822年可能是Deltochilini sensu Tarasov & Dimitrov(2016)（金龟子科：金龟子科）部落中最具物种性的属，传统上被分为八个亚属。其中，1946年的Deltohyboma Lane亚属最多，共有47种，其中有5种（D. genieri sp. nov.， D. gilli sp. nov.， D. susanae sp. nov.， D. bolivariensis sp. nov.和D. inesae sp. nov.），还有至少165种未被描述。由于种类众多，并且为了实用的目的，这里将该亚属划分为19个种群，将D. inesae sp. nov.留作incertae sedis。这种种群的划分将有助于物种的可靠鉴定，并将有助于完成亚属的修订。这篇报道是Deltohyboma亚属分类修订的第一部分；它是基于对所有模式标本和近9800个标本的检查，其中大约1200个（主要是男性）研究了他们的生殖器。本文所确认的19个种群，主要是基于Deltohyboma首次描述的特征，即a) clypeus的前缘（在clypeth牙齿之间），b) hypomera的内缘，c) protibia的腹侧面，d) metafur的后缘，以及e)该群的aedeagus和endoophallus的首次详细研究所产生的几个新特征。提供了物种群的诊断、描述、地理分布、组成和识别关键（雄性以及雄性和雌性）。
Deltochilum Eschscholtz, 1822 is perhaps the most speciose genus of the tribe Deltochilini sensu Tarasov & Dimitrov (2016) (Scarabaeidae: Scarabaeinae) and has been traditionally divided into eight subgenera. Among them, the subgenus Deltohyboma Lane, 1946, is the most speciose with 47 species, five of which are described here (D. genieri sp. nov., D. gilli sp. nov., D. susanae sp. nov., D. bolivariensis sp. nov. and D. inesae sp. nov.), and at least 165 species still undescribed. Due to the large number of species, and for practical purposes, the subgenus is here divided into 19 species-groups, with D. inesae sp. nov. left as incertae sedis. This division into species-groups will help in the reliable identification of species and will aid in the completion of the revision of subgenus. This report is the first part of the taxonomic revision of the subgenus Deltohyboma; it is based on the examination of all type specimens and almost 9,800 specimens of which approximately 1,200, mostly males, had their genitalia studied. The 19 species-groups recognized here are based mainly on characters described for the first time for Deltohyboma, namely, the state of a) the anterior margin of the clypeus (between the clypeal teeth), b) the internal margin of hypomera, c) the ventral face of the protibia, d) the posterior margin of the metafemur, and e) several new characters resulting from the first detailed study of the aedeagus and the endophallus of the group. Diagnosis, description, geographic distribution, composition and identifications keys (for males as well as males and females) for the species-groups are provided.
