Dung beetles from two sustainable-use protected forests in the Brazilian Amazon.

Background: The Amazon Forest is one of the world's most biodiverse ecosystems and yet its protected areas are understudied concerning insects and other invertebrates. These organisms are essential for tropical forests due to their ecological processes, with some species being very sensitive to habitat disturbances. Dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae) have been used as bioindicators for more than 30 years and were surveyed to assess the insect biodiversity of two sustainable-use forest reserves in the Brazilian Amazon.

A new species of Polynoncus Burmeister (Coleoptera: Trogidae) from Argentina.

Trogidae (Coleoptera) is a cosmopolitan family with about 350 described species within five extant genera (Zídek 2013, 2017; Strümpher et al. 2014, 2016; Nikolajev 2016). For South American, three genera are recorded: Trox Fabricius, 1775 (Troginae), Omorgus Erichson, 1847 (Omorginae), and Polynoncus Burmeister, 1876 (Omorginae) (Scholtz 1990; Strumpher et al.

Factors Affecting the Composition and Succession of Beetles in Exposed Pig Carcasses in Southern Brazil.

Coleoptera is one of the largest taxon among animals and exhibits diverse eating habits. When associated with decaying corpses, beetles can be of great value in estimating the postmortem interval. In order to consolidate a useful database for the forensic field, it is necessary to study the entomological fauna associated with the carcasses in different geographical regions since the diversity of insects varies according to the biogeoclimate zone.

Redescription and new records of Ontholestes brasilianus Bernhauer, 1906 (Coleoptera: Staphylinidae: Staphylininae).

The genus Ontholestes Ganglbauer includes 35 species distributed mainly in Eurasia, with a few additional species in Africa and North and South America (Herman, 2001; Yang Zhou, 2012; Smetana Shavrin, 2013; Rougemont, 2016). According to Asenjo et al. (2013), the South American record of the Palearctic species Ontholestes murinus (Linnaeus, 1758) for Brazil made by J.
