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.

Checklist of Staphylinidae (Coleoptera) of El Salvador.

This paper is primarily a compilation of published data on the staphylinid beetle species reported for El Salvador. It is based on taxonomic and ecological literature, with inclusion of some new records from different entomological collections. Thirty eight genera and 96 species are reported in the list, including a first country record: Eulissus chalybaeus.

Complete mitochondrial genome of a cave dwelling (Insecta: Coleoptera: Dytiscidae) from the Eastern Amazon.

Coleoptera presents most of the cave fauna biodiversity, with several troglobite species belonging to the aquatic family Dytiscidae. However, very little is known on both genetic and genomic diversity traits of Neotropical cave beetles. Thus, here we present the complete mitochondrial genome sequence of five specimens of collected in a ferruginous cave from Serra dos Carajás in Parauapebas (Pará, Brazil, Eastern Amazon).

Euconnus franzi Asenjo, new name on Neotropical Euconnus Thomson (Coleoptera: Staphylinidae: Scydmaeninae: Glandulariini).

During my doctoral studies, while assembling a taxonomic list of the Staphylindae of Brazil (Asenjo et al. 2013: 229), I found a primary junior homonym in the genus Euconnus Thomson. The purpose of this note is to provide a correction to this problem.

Assessment the short-term effects of wrack removal on supralittoral arthropods using the M-BACI design on Atlantic sandy beaches of Brazil and Spain.

Wrack removal has been adopted indiscriminately, with no previous assessment of the ecological implications for sandy beach ecosystem. This study evaluated, through an M-BACI design, the effect of wrack removal on supralittoral arthropods on Atlantic sandy beaches receiving different types of wrack: mangrove propagules (Brazil), seagrasses and macroalgae (Spain). Impacted plots were contrasted with controls in 8 successive periods before and after experimental wrack removal.
