Abstract

Herein one new species of Amazhomidia Cipola & Bellini from Brazilian Amazon is described and illustrated: A. thaisae sp. nov., plus one specimen no nominal due to lack of material for formal descriptionend point.  Acanthocyrtus guianiensis Womersley is redescribed and transferred to Amazhomidia by presence of prelabral chaetae bifurcated, macrochaetotaxy pattern, manubrium laterally with long distal mac finely ciliate and dens ventrally unscaled. Acanthocyrtus croceus Womersley is confirmed as a junior synonymy of A. guianiensis. The juvenile description of Amazhomidia ducke is provided, and changes in chaetotaxy nomenclature are made based on them. Acanthocyrtus lineatus Womersley is redescribed based on type material and new diagnostic characters are revealed. Identification keys for both genera and a comparison for Entomobryinae genera with dental spines are provided. Amazhomidia has now three and Acanthocyrtus Handschin six valid species.
