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.

The majority of works on this order includes species descriptions, with rare references to behavioral aspects. As such, the present study describes the behavioral repertoire, and the activity and feeding periods of Rowlandius potiguar (Schizomida: Hubbardiidae) in the laboratory.
