Potamophilops bragaorum sp. nov. is described and illustrated based on adult specimens collected in a mountainous area in the Cerrado biome in Taquaru\ç\ú district, Tocantins state, Brazil. This is the second species described in the genus and it represents the northernmost record of Potamophilops, which is known only from Argentina and Brazil. In this article we provide a diagnosis, details on the morphology and images of the habitus and structures used to determine the species and to distinguish the gender. Field observations permitted the description of some aspects on the biology of the new species that seem to be very similar to those of other Larainae genera. Examination of gut contents revealed a diet based mostly on periphyton.

The genus Portelmis Sanderson, 1953 and the species P. gurneyi Spangler, 1980 are reported for the first time in Brazil. Portelmis kinonatilis sp. nov. and P. paulicruzi sp. nov. are described and illustrated based on adult specimens collected in two different municipalities in the state of Amazonas, Brazil. Diagnoses and illustrations of all Portelmis species, and a taxonomic key to identify males are presented.

Hintonelmis anamariae sp. nov. is described and illustrated based on adult specimens collected in Presidente Figueiredo Municipality, Amazonas State, Brazil. This species can be distinguished from all other known Hintonelmis species by its dorsal color pattern and the morphology of the male genitalia.
