Abstract Eight new species of Embioptera from Brazil are described, diagnosed, and illustrated. For Anisembiidae: Chelicercaachilata Szumik, Pereyra & Juárez, sp. nov.; Saussurembiaborba Szumik, Pereyra & Juárez, sp. nov. For Archembiidae: Archembiaoruma Szumik, sp. nov.; Embolynthaoriximina Szumik, Pereyra & Juárez, sp. nov.; Pararhagadochirbonita Szumik, Pereyra & Juárez, sp. nov., Pararhagadochirmarielleae Szumik, Pereyra & Juárez, sp. nov.; Pararhagadochirpara Szumik, Pereyra & Juárez, sp. nov. For Clothodidae: Chromatoclothodalanga Szumik, Pereyra & Juárez, sp. nov. To clarify the higher classification of the Order and to have an accurate taxonomy, a species catalog and introduction to the four families present in Brazil is also detailed, including phylogenetic relationships, taxonomic actions, composition, distributions, and records maps. Herein, several taxonomic acts are proposed: (1) the synonymy of Chelicerca Ross (= Dactylocerca Ross confirmed junior synonym; = Schizembia Ross syn nov.; = Pelorembia Ross, confirmed junior synonym; = Cryptembia Ross, syn. nov.) and Saussurembia Davis (= Stenembia Ross, syn. nov.). (2) new status and delimitation for family Archembiidae Ross, stat. rev.; subfamily Archembiinae Ross, stat. rev.; subfamily Pachylembiinaestat. rev.; subfamily Scelembiinaestat. rev., and their genera included. (3) Diradiusunicolor (Ross) (Teratembiidae) comb. nov., and (4) new locality records for previously cited species in the region.
