Abstract

Three new Brazilian species of Holcobunus Roewer, 1910 are described, thus increasing the total number of species in the genus to five: Holcobunus bicornutus Mello-Leitão, 1940, H. nigripalpis Roewer, 1910, Holcobunus dissimilis sp. nov. (type locality: Espírito Santo, Santa Teresa, Reserva Biologia Augusto Ruschi), Holcobunus ibitirama sp. nov. (type locality: Espírito Santo, Ibitirama, Santa Marta, close to Parque Nacional Caparaó), and Holcobunus uaisoh sp. nov. (type locality: Minas Gerais, Fervedouro, Parque Estadual Serra do Brigadeiro). A new record for Holcobunus nigripalpis Roewer, 1910 from Minas Gerais is also provided and the morphological variation in both penis and somatic morphology in the genus are presented and discussed. These observations enhance our understanding of both the diversity and distribution of Holcobunus.
