New taxonomic insights for Brazilian Reitter (Coleoptera: Staphylinidae: Pselaphinae), including three new species and their mitochondrial genomes.

Here we present a taxonomic treatment for the Brazilian species of (Reitter, 1882), including the description of three new species ( Asenjo & Valois , Asenjo & Valois and Asenjo & Valois ) from the Quadrilátero Ferrífero (Minas Gerais, Brazil). In addition, we designated lectotypes for the Brazilian species of species-group 2, (Raffray, 1898), (Reitter, 1888), (Reitter, 1888), (Raffray, 1898), and (Schaufuss, 1887), besides recognizing the holotype for (Reitter, 1882), (Raffray, 1898), and (Raffray, 1898). The mitochondrial genomes (mitogenomes) of the three new species are presented, for which we present the phylogenetic placement among Staphylinidae with previously published data.

The complete mitochondrial genome and description of a new cryptic Brazilian species of Raffray (Coleoptera: Staphylinidae: Pselaphinae).

Raffray, 1908 is a genus of South American rove beetles typically found in tropical humid forests. Here we describe a new cryptic species from Eastern Amazon, in northern Brazil, Asenjo , and its major morphologic diagnostic features, which were photographed and illustrated. In addition, we bring the complete mitochondrial genome sequence of , and its position within the phylogenetic context of the family, including previously available mitogenomes of Staphylinidae species.

Taxonomic revision of the Dichotomius sericeus (Harold, 1867) species group (Coleoptera: Scarabaeidae: Scarabaeinae).

The Dichotomius sericeus species group of the subgenus Luederwaldtinia is reviewed. This group comprises eight species endemic to the South American Atlantic forests, Caatinga and associated areas of Brazil, Paraguay and Argentina: Dichotomius sericeus (Harold, 1867); Dichotomius irinus (Harold, 1867); Dichotomius laevicollis (Felsche, 1901); Dichotomius schiffleri Vaz-de-Mello, Gavino Louzada, 2001; Dichotomius guaribensis sp. nov.
