Ecological niche modeling of two Microtheca Stål, 1860 species (Coleoptera: Chrysomelidae: Chrysomelinae) in the Americas: insights from Brassicaceae occurrence.

Biological invasions pose significant threats to biodiversity, with invasive species spread often facilitated by human activities. Consequently, this research utilized ecological niche modeling (ENM) to overcome this limitation and map the potential suitability of Microtheca ochroloma Stål, 1860 and Microtheca semilaevis Stål, 1860, which have been evaluated as potential insect pests in the Americas, zones for four genera of Brassicaceae, which include globally cultivated species such as Sinapis L., Raphanus L.

A New Species of Synoemis Pascoe, 1863 (Coleoptera, Cucujoidea, Silvanidae): the First Record of the Genus in the New World.

A new species of Synoemis Pascoe, 1863 (Silvaninae) is described and illustrated based on one female specimen from Boa Vista, Roraima state, Brazil. Synoemis jandersoni sp. nov.

Richness and similarity of Passalidae (Coleoptera: Scarabaeoidea) from biological collections in the Brazilian Amazon.

Scientific collections are important sources of information on biodiversity that can be useful for faunistic, taxonomic and phylogenetic studies. The aim of this study was to investigate the fauna of Passalidae deposited in the zoological collections in the States of the Brazilian Amazon. 14,652 Passalidae specimens are deposited in scientific collections, distributed in two subfamilies, 7 genera and 82 species.

Dung beetle communities: a neotropical-north temperate comparison.

Dung beetle communities have been compared across north temperate latitudes. Tropical dung beetle communities appear to be more diverse based on studies using different methodologies. Here, we present results from a standardized sampling protocol used to compare dung beetle communities across five neotropical forests in Brazil and Ecuador and two warm, north temperate forests in Mississippi and Louisiana.
