New genera of Neotropical Maindroniidae, with a redescription of Maindronia neotropicalis (Insecta, Zygentoma)

Maindroniidae is a rarely-encountered monogeneric family of Zygentoma, of which only four species are described so far. Recent surveys in the Atacama Desert have revealed in the hyperarid core an astonishing molecular and morphological diversity of these insects. The present work aims to provide the basis for a systematic taxonomic analysis of this diversity. The former Maindronia neotropicalis from Chile is redescribed in a new genus as Atacamus neotropicalis , along with a second new genus and species, Peruatacamus atunpacha from Peru. Neotropical Maindroniidae are separated from Old World Maindroniidae and placed in the new subfamilies Atacaminae and Maindroniinae respectively.
