“…However, as inevitably happens to any publication in an active field of scientific inquiry, the work is, at some points, already outdated. Four new genera have since been described (Geńier, 2010;Roggero et al, 2016;Gonzaĺez-Alvarado et al, 2019;Pacheco and Vaz-de-Mello 2019a) (one of them, Lobidion Geńier, 2010, not included in the key, has since been lowered to a subgenus of Ateuchus; Geńier and Cupello, 2018), a subgenus has been reelevated to genus, Boreocanthon (Edmonds, 2022), a new subgenus has been described, Canthon (Bajacanthon) (Halffter et al, 2022a), the subgeneric classification of Dendropaemon has been completely modified, including the recognition of 12 subgenera in contrast to the previous three (Geńier and Arnaud, 2016;Cupello and Geńier, 2017), some names used as valid in the key have now been invalidated (viz., Eucanthidium Martıńez and Halffter, 1986, Luederwaldtinia Martıńez, 1951, Telhyboma Kolbe, 1893, Tetramereia Klages, 1907, and Vulcanocanthon Pereira and Martıńez, 1960 (Geńier, 2012;Geńier and Arnaud, 2016;Cupello, 2018;Nunes and Vaz-de-Mello, 2019;Vieira et al, 2019), some genera have been re-delimited and the key is no longer adequate to identify them completely (e.g., Sylvicanthon and Tetraechma) (Cupello and Vaz-de-Mello, 2018;Nunes and Vaz-de-Mello, 2022), and some names, due to nomenclatural problems discovered since 2011, have changed their allocation and denote different taxa in the key than they now do (e.g., Selenocopris and Canthidium s. str.)…”

After almost two decades of stagnation, the taxonomy of the New World Scarabaeinae dung beetles has since 1988 been going through a period of great effervescence. In the last 35 years, 81 complete revisions and 69 supplements have been produced by 86 authors based in 15 countries, addressing the taxonomic status of 950 species. This is what we christen as the Taxonomic Revolution of New World dung beetles. We review the history and products of this revolution, explore its causes and its apparent exceptionalism among most other New World Coleoptera groups, and point to the many great challenges that still face the scarabaeine taxonomists. An aspect of interest to ecologists is the coevolution of the Taxonomic Revolution with what we call the Ecological Revolution of dung beetles, i.e., the similar expansion in ecological studies about these organisms. We argue that it has been the continuous feedback between these two simultaneous processes that has enabled each of them to exist and flourish: without the Ecological Revolution, the Taxonomic Revolution could not have existed, and vice-versa. Ecologists and taxonomists are partners in the scientific enterprise, symbionts one may say.

“…However, both molecular and morphological systematics analyses have shown it to be highly polyphyletic and composed of numerous lineages (Philips et al 2004b, Monaghan et al 2007, Tarasov and Génier 2015, Tarasov and Dimitrov 2016). Tarasov and Dimitrov (2016) reduced the tribe, Deltochilini, to just 20 genera comprising 457 valid species that are endemic to the Neotropical and Nearctic regions where they are, essentially, sister to other prominent tribes and lineages of these 2 regions (Halffter and Martínez 1977, Vaz-de-Mello et al 2011, González-Alvarado and Vaz-de-Mello 2014, 2021a, 2021b, Valois et al 2015, Cupello and Vaz-de-Mello 2018, Nunes et al 2018, 2020, Vaz-de-Mello and Cupello 2018, González-Alvarado et al 2019, Sawaris et al 2019, Silva and Valois 2019, Edmonds 2022, Halffter et al 2022, Nunes and Vaz-de-Mello 2022, Cupello et al 2023). To maintain monophyly within the Deltochilini this decision leaves many former Afrotropical, Madagascar, Oriental, Australian, and further Neotropical deltochiline genera without a certain tribal placement.…”

The subfamily Scarabaeinae has been traditionally divided into tribes on the basis of morphological similarity between groups of genera or, even, dissimilarity shown by a single genus. Although various tribal units have been described over the past 220 years, they had been recently reduced to a maximum of only 12 through synonymies within some tribes. However, following the advent of morphological and molecular cladistic systematics, it is clear that there are many discrepancies between phylogeny and phenetic tribal classification. As a result the number of tribes has now been expanded to 20 by revalidating some tribes or describing new groupings although this revision is incomplete. Thus, this study provides a comprehensive review of the current status of dung beetle tribal classification with regards to validity in terms of monophyly versus polyphyly or paraphyly. We discuss the systematic position of tribes among Scarabaeinae and provide a summary of the generic and species structure for each tribe. Given the enduring polyphyly or paraphyly in several tribes, it is clear that further tribal units will need to be described or revalidated to resolve the discrepancies. Therefore, we discuss how to use multiple lines of evidence (molecular, morphological, biogeographical, and paleontological) to build the tree of life for dung beetles and consequently provide stability in the tribal classification of the lineage.

“…Not long after of the works of Paulian [ 8 , 9 ] and Balthasar [ 30 ], some American scarabaeidologists recognised the need for a taxonomic revision of Deltochilum due to its heterogeneity, the amount of divisions (subgenera) and the numerous new species remaining to be described in collections [ 34 – 38 ]. The attempt towards a modern and comprehensive taxonomic revision of Deltochilum focused on subgenera resulted in the description of 24 new species [ 25 , 26 , 33 , 39 , 40 ] and the description of new genus [ 41 ].…”

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.
