Abstract
Recent efforts with Malaise trap sampling in Serra dos Órgãos and Itatiaia, in Brazil, allowed us to identify and describe three new species from the first locality: Hylotribus humeralis sp. nov., H. nanico sp. nov. and H. queirozi sp. nov. New records of H. plaumanni Queiroz & Mermudes, 2014 for both localities and H. sublimis Queiroz & Mermudes, 2014 for the latter are also presented. We also describe morphological variability including aptery and microptery, and male genitalia, for H. plaumanni. We produce a new key to the species and discuss the species relationships and wing variation for the genus.
