Article
Full-text available
The evolutionary dynamics and phylogenetic utility of mitochondrial genomes (mitogenomes) have been of particular interest to systematists and evolutionary biologists. However, certain mitochondrial features, such as the molecular evolution of the control region in insects, remain poorly explored due to technological constraints. Using a combinatio...

The Onthophagus chevrolati Harold, 1869 (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) species complex was recently studied, and a majority of its species were newly described or redescribed (see Moctezuma & Halffter 2020). Onthophagus viridichevrolati Moctezuma & Halffter, 2020 was the only species within the O. chevrolati species complex...

ABSTRACT Data from literature was gathered to compile the checklist of the fauna of Onthophagus of Mexico. A total amount of 120 species was found, with 85 endemics to Mexico. The distributional pattern as originally proposed by Halffter (1964) and commentaries of the majority of the species are provided. Records of species were found for all the...
Article
Full-text available
Abstract. Deltochilum burmeisteri Harold, 1867 has been considered as a junior subjective synonym of D. mexicanum Burmeister, 1848 for almost 8 decades. Nevertheless, D. burmeisteri is resurrected herein from previous synonymy based on the revision of the external and genital morphology. The lectotype for D. burmeisteri, a female specimen, is desig...

Article
Full-text available
Spatial autocorrelation is a general property of ecological variables. Since many of the statistical methods used in ecology often assume sample independence, spatial clustering is considered a source of noise in studies related to the estimation and monitoring of biological diversity. Spatial autocorrelation was assessed herein in a Mexican Scarab...

In this study, we take the Onthophagus chevrolati species group, likely a monophyletic species group as an example to analyze the processes that led to the biogeographic integration of the Holarctic fauna in the mountains of the Mexican Transition Zone to test our biogeographic hypotheses. We propose a change from the status of subspecies to specie...

Full-text available
Beta diversity is often a dominant characteristic in mountain systems and naturally fragmented ecosystems. However, natural protected areas are traditionally designed to protect ecosystems with high alpha and low beta diversity. Recent information about dung beetles of the Transmexican Volcanic Belt was used to identify the most suitable strategy f...

Onthophagus Latreille is a hyperdiverse genus of dung beetles that has ≈2200 described species. Onthophagus in the Americas has been divided into seven species groups: chevrolati, clypeatus, gazellinus, hircus, landolti, mexicanus and dicranius. The chevrolati species group is characteristic of the mountains of the Mexican Transition Zone and is di...

Beta diversity is often a dominant characteristic in mountain systems and naturally fragmented ecosystems. However, the dominant models of natural protected areas were traditionally designed without considering beta diversity and complementarity. We used recent information about dung beetles of the Trans-Mexican Volcanic Belt to identify the divers...
