Description of a new species of Bothynus Hope from Argentina and Bolivia (Coleoptera: Scarabaeidae: Dynastinae)

Abstract

A new species of Bothynus Hope, 1837 (Coleoptera: Scarabaeidae: Dynastinae: Pentodontini) is described from the eastern Andes in South America. The new species is unique in the genus for having the elytra and part of the pronotum covered with small setae.

The genomes of Hercules beetles reveal putative adaptive loci and distinct demographic histories in pristine North American forests

“…Specifically, the forest habitat types of the four species are detailed below. D. maya occurs in tropical and montane broadleaf rainforests from Guatemala, Honduras and the Mexican state of Chiapas (Figure 1a), with the majority of occurrence data located at 500–1500 m above sea level (Hardy, 2003; Huang, 2017; Morón, 2009; Ratcliffe et al., 2013; Ratcliffe & Cave, 2006). Recently, D. maya has been observed in temperate mixed forests in the Mexican states of Oaxaca (Moctezuma & Sánchez‐Huerta, 2018) and Puebla (García‐Morales et al., 2022).…”

Previous studies based on palaeoclimatic data have revealed that the LIG was a time when the global climate was as warm or warmer than at present, where temperate mixed forests were in areas with similar vegetation as at present (Kukla et al, 2002), which corroborates the estimated effective population size in D. grantii and D. hyllus.…”
