“…as: Palaeoamerican Montane, Palaeoamerican Plateau, Tropical Palaeoamerican, Mesoamerican Montane, Plateau, Neotropical and exotic. These distribution patterns have been used to determine the origin and integration of the insects in the MTZ, and we assume that there is a common history of colonization or speciation in each pattern (R€ os et al, 2011;Alvarado et al, 2014). At the generic level, there are only two main patterns: Holarctic and Neotropical.…”

“…At the generic level, there are only two main patterns: Holarctic and Neotropical. However, in one genus it is possible to find different lineages that have penetrated the MTZ in ancient (Miocene) and modern (Pliocene and more recent) times (Alvarado et al, 2014). To detect whether the relative frequencies of these groups of species were independent of habitat condition, we used the chi-square test for contingency tables.…”

“…For Scarabaeinae dung beetles there are species of recent (Neotropical), intermediate (Mesoamerican), and ancient (Palaeoamerican and Plateau) distribution patterns (Halffter, 1964(Halffter, , 1976, and with Gondwanan and African origins (Emlen et al, 2005;Monaghan et al, 2007;Davis, 2009). These patterns have been widely used to test different ecological and biogeographical hypotheses in the MTZ (Marshall & Liebherr, 2000;Morrone, 2005Morrone, , 2010Escobar et al, 2007;R€ os et al, 2011;Alvarado et al, 2014).…”

Aim We analysed the effects of grazing on the diversity and structure of dung beetle communities to see whether the biogeographical and ecological contexts influence dung beetle responses. We hypothesized that the responses of dung beetle communities are modulated by both the ecological conditions resulting from the transformation of native vegetation into grazing areas, and the history of the species inhabiting different biogeographical provinces. Location The state of Hidalgo, in the Mexican Transition Zone, central Mexico. Methods We used a standardized hierarchical sampling procedure in three biogeographical provinces located in Hidalgo. Within each province, we identified the dominant vegetation types, and within these we identified the sites with native vegetation and those modified by grazing. The design included 800 baited pitfall traps, and allowed us to study the response of dung beetle communities with different biogeographical histories to ecological context. Results We captured 8707 beetles belonging to 37 species and 17 genera in the subfamily Scarabaeinae. We found that grazing areas only had a negative effect on dung beetle diversity in tropical forest; conversely, in dry environments (pine–oak forest and xerophilous scrubland) diversity in grazing areas was higher than in the native vegetation sites. We did not detect a clear effect in cloud forest sites. Species turnover between the native vegetation and pastures was high locally, and low over larger spatial scales (vegetation type or biogeographical province). In all four vegetation types grazing was associated with differences in dung beetle community composition. Main conclusions The impact of grazing on dung beetle diversity is dependent to a considerable degree on the local ecological conditions and the biogeographical context that has shaped the composition of communities over time.

“…The Sierra Norte shows considerable influence from elements stemming from the Sierra Madre Oriental and the Trans Mexican Volcanic Belt (Kohlmann in press). Finally, Alvarado et al (2013) cite three georeferenced localities at La Chinantla. With the present collecting localities, we can recalculate and correct the Trotta-Moreu et al (2008) too low mean value for altitude for this species.…”

An analysis of vicariant speciation of Geotrupes and Phanaeus (Coleoptera, Geotrupidae, Scarabaeidae) from the mountains of Oaxaca, Mexico is undertaken. The new species of dung beetle (Coleoptera: Scarabaeidae) from Oaxaca, Mexico, Phanaeus dionysius sp. n. is described. Photos of the habitus and a distribution map are provided. Phanaeus malyi Arnaud is revalidated. An updated key for the Phanaeus endymion species group and new localities are also presented. An updated key for the Geotrupes of Oaxaca and new locality records are also submitted.
