N2 - In this paper, we reassess the status of the two genera of scaled Entomobryinae with dental spines (Acanthocyrtus and Acanthurella) and we erect a new genus (Sinhomidia) on the basis of scale morphology and scale distribution. Scales are partially pointed in Acanthocyrtus and all rounded in Acanthurella. The new genus, Sinhomidia, has pointed scales, but lacks dental scales contrary to Acanthurella and Acanthocyrtus; in addition, it exhibits a unique dorsal macrochaetotaxy. Three new species of Acanthocyrtus are described (Acanthocyrtus yolngui sp. nov., Acanthocyrtus loftyensis sp. nov., Acanthocyrtus barrowensis sp. nov.) and two are redescribed [Acanthocyrtus spinosus (Schött, 1917), Acanthocyrtus lineatus Womersley, 1934]. One species (Acanthocyrtus bicolor Yosii, 1965) of the genus is redescribed and transferred to the new genus Sinhomidia. A key to the scaled Entomobryinae genera with dental spines and a key to the eight known Acanthocyrtus species are provided.
