The genus comprises approximately 25 valid species distributed across the Holarctic region, with the majority described or redescribed in a comprehensive 2002 revision. Holarctic species are organized into five species groups based on phylogenetic analysis, replacing the previous subgeneric classification system.

A small rove beetle in the genus Amarochara, described by Blatchley in 1910. It is one of 25 valid species recognized in the Holarctic revision of the genus. The species belongs to a group characterized by specific morphological traits and shares the genus-wide trait of apparently utilizing subterranean habitats for reproduction and hibernation.
Amarochara forticornis
Amarochara forticornis is a rove beetle species in the tribe Oxypodini, originally described by Lacordaire in 1835. It is one of 25 valid species recognized in the Holarctic revision of the genus Amarochara. The species has undergone taxonomic clarification, with previous synonymies resolved. It is assigned to one of five species groups established for Holarctic representatives of the genus.

Dinardina
Dinardina is a subtribe of rove beetles (Staphylinidae) within the tribe Oxypodini, subfamily Aleocharinae. It was established by Mulsant & Rey in 1873. The subtribe contains small to minute beetles associated with ant colonies. Members exhibit myrmecophilous (ant-associated) lifestyles, though specific ecological relationships vary among included genera. The subtribe is primarily documented from European faunas.
Hylota ochracea
Hylota ochracea is a rove beetle in the family Staphylinidae, subfamily Aleocharinae, described by Casey in 1906. The species has been introduced from North America to parts of Europe.
