A Classification of the Orchesellinae with a Key to the Tribes, Genera and Subgenera (Collembola: Entomobryidae)

A formal classification of the subfamily Orchesellinae is presented for the first time. The tribe Orchesellini houses Orchesella, Neorchesella, Pseudodicranocentrus and Dicranocentrus . The tribe Corynotrichini includes Corynothrix and Orchesellides. The new tribe HETEROMURINI houses Heteromurus and Indoscopus, and the new tribe MASTIGOCERINI is erected for Mastigoceras . Complete synonymy is presented for all the genera and references to literature discussing their taxonomic status is included. The taxonomic status of Verhoeffiella, Typhlopodura and Heteromurodes is discussed. The former is regarded as a subgenus of Heteromurus and the latter two are treated as synonyms of that same genus. It is concluded that the presence or absence of antennal annulations is not a character of generic importance in this subfamily. A key to the tribes, genera and subgenera of the Orchesellinae is included.
