Rio de Janeiro: one male at CMNC labelled ‘ BRASIL Eº Guanabara Rio de Janeiro CORCOVADO Alvarenga-leg. Coll. Martínez. Nov:956/H. & A. HOWDEN COLLECTION ex. A.

 Diagnosis   
 P. oliveirai sp. nov. can be easily separated from the other species of the genus by having short parameres with somewhat rounded (in lateral view, Figure 6 (d)) apices and widely bifurcated lobes of the anterior frontoclypeal process (Figure 6 (a)).   
 Description   
Holotype, male (Figure 6 (a, d–f)).  
Body length 7.3 mm. Colour uniformly dark brown.  
Anterior frontoclypeal process long and wide, as wide as head, widely sinuate medially, with asymmetric lateral lobes; the lobes distinctly excavated apically, in lateral view they have lateral angles directed caudally.  
Pronotum slightly narrower than elytra, deeply excavated in middle. Lateral pronotal processes almost rounded, their hind margins not carinate. Pronotum coarsely punctate to rugose except for apices of lateral pronotal processes and a narrow area near anterior margin.  
Aedeagus with short parameres: ratio phallobase width/paramere width 2.7 (Figure 6 (d)). Apices of parameres rounded in lateral view and dorsal view (Figure 6 (d, e)). Endophallus without a group of spinules (Figure 6 (f)).  
 Female unknown.   
 Variation   
Body length of the paratypes varies from 6.8 to 7.5 mm. The paratypes have less developed anterior frontoclypeal processes (Figure 6 (b, c)) than the holotype.  
 Distribution   
The species is known from two localities in the Brazilian states of Goiás and Minas Gerais (Figure 7). The record from Corcovado Mountain in Rio de Janeiro is doubtful and not therefore mapped.  
 Etymology   
The new species is named after Dr Charles Martins de Oliveira, from Embrapa Cerrados in Brasília, who obtained the specimens from Morrinhos.
