Two new species of the genus Ateuchus Weber are described from the region of Los Chimalapas, Oaxaca, Mexico: A. benitojuarezi sp. n. and A. colossus sp. n. A diagnosis for distinguishing these new species from the other species of this genus in North America is included. This paper is illustrated with pictures of the dorsal habitus and the male genitalia of the new species. The evolutionary relationships of the species are discussed, as well as their distribution and ecology. It is considered that the species of the genus Ateuchus present in North and Central America correspond to the Typical Neotropical and Mountain Mesoamerican distribution patterns.

“…Recovered beetles were stored in 70% ethanol and subsequently were separated, counted, and identified to species level using the taxonomic keys and descriptions of Rivera-Cervantes and Halffter (1999), Kohlmann and Solís (2001), Génier and Kohlmann (2003), Delgado and Kohlmann (2007), Génier (2009), Edmonds and Zídek (2010), González-Alvarado and Vaz-de-Mello (2014), Kohlmann and Vaz-de-Mello (2018), Moctezuma et al (2019), Arriaga-Jiménez et al (2020, and Halffter (2020, 2021).

In this study, we compared the Scarabaeinae (Coleoptera) assemblages between two contrasting habitats (conserved forest versus urban habitat), located between the boundary of an urban zone and a protected area within the Mexican state of Chiapas. We collected 1003 individuals of 22 species and 12 genera. The composition of assemblages was similar between habitats, with a high species dominance. However, the identity of the dominant species differed between habitats, with 11 species considered indicators of one of the two conditions (five species in the conserved forest sites and six species in urban habitat sites), whereas three other species exhibited generalist habits. Large paracoprids predominate in the conserved forest, and small paracoprids in the urban habitat. The apparent homogeneity in the dung beetle assemblages probably is due to the high density of domestic and feral animals replacing native mammals and is promoted by the loss of forest-dependent species caused by continuous landscape fragmentation. Nonetheless, the association of some species with forest habitat and the differences in the structure of functional groups indicate the importance of conserving these forest remnants, which would help to mitigate the negative impact of urbanised areas, as these species are generally sensitive to the habitat fragmentation process.

“…Although it was already known from previous phylogenies that the Ateuchini were polyphyletic (Philips et al 2004b, Monaghan et al 2007, Tarasov and Génier 2015, Tarasov and Dimitrov (2016) sequenced 21 of the genera studied by Montreuil (1998) and showed that they occurred in 13 different lineages scattered across the phylogeny. They redefined the Ateuchini to accommodate only 21 genera and 181 valid species distributed in the Neotropical and Nearctic regions (Vaz-de-Mello 2008, Génier 2015, Génier and Cupello 2018, Kohlmann and Vaz-de-Mello 2018, Lopera-Toro et al 2020, Cupello 2022, Cupello et al 2023) awarding all other former members of Afrotropical, Oriental, and Australasian genera the status of incertae sedis. Nevertheless, as recently redefined, the Ateuchini remain polyphyletic.…”

Dung beetle tribal classification (Coleoptera: Scarabaeidae: Scarabaeinae): progress, problems, and prospects

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.
