• Oliverius Soares and Soares 1945: 263 .

Type species: Oliverius jordanensis Soares & Soares, 1945 , by original designation.

Etymology: As communicated by Soares and Soares (1945), the name was dedicated to the ornithologist Dr Olivério Mário de Oliveira Pinto.

Diagnosis: Oliverius can be distinguished from the other genera of Neopachylinae due to (1) DS outline of the males gamma-pyriform ‘ Gonyleptes -like’ sensu Kury and Medrano (2016) ( Fig. 32B ); (2) Scutal area IV divided into left and right halves by a longitudinal median groove ( Figs 31A , 32B ); (3) Free tergites I– III with two or three pairs of paramedian conspicuous tubercles ( Figs 31A , 32B ); (4) Females’ free tergites I– III with a row of outstanding subconical tubercles ( Figs 30F , 31D–E , 32I ); (5) Pedestal on the glans square-shaped ( Fig. 33B, D); 6) Ventral process of the glans as wide as the stylus ( Fig. 33B, D).

Distribution: BRAZIL: states of Minas Gerais, Rio de Janeiro, and São Paulo ( Fig. 29 ).
