Popis: Bolbapium dutraorum Carvalho and Vaz-de-Mello, sp. nov. (Figures 3b, 14a) Diagnosis Clypeo-frontal carina clearly much wider than frontal carina; groove on the back of the frons, behind the carina. Pronotum mesoanteriorly with almost bituberculated tubercle (Figure 3b). Etymology. Named after Luan Dutra and Isabela Dutra, beloved brother and sister of the first author. Type locality. Cuiabá, Mato Grosso, Brazil. Holotype. ‘UNIVAG/ 5.iv.2004 / Cuiabá, MT/ Silva, F’ (CEMT 74768). Paratypes. 3 specimen examined. BRAZIL: Mato Grosso, Porto Esperidião, [16°1 ʹ 29”S, 59°0 ʹ 44”W], xi.1984, Magno & Alvarenga leg. (1 CEMT); Rosario Oeste, Dirings leg. (2 MZUSP). Description Body size: Length: 5.97–6.17 mm. Width: 4.59–4.80 mm. Head: Clypeo-frontal carina clearly much wider than frontal carina. Canthus presents unevenly distributed spots and setae from the ventral region. Front presents arched carina, without formation of tubercles on each side and a groove behind the carina; region between the carina and the clypeus with small depression; every surface with sparse and unevenly distributed points. Pronotum: Anterior region of the disc with little-developed tubercles, almost bidentate, small depression in the region immediately lateral to the tuber. Sexual dimorphism: It was not possible to observe as all specimens are female. Remarks: The primary type is deposited at the CEMT. Differential diagnosis. Bolbapium dutraorum sp. nov. is morphologically similar to B. striatopunctatum and B. sergioidei sp. nov. in presenting the forehead with a transverse carina without tubercle formation on each side. However, it is easily distinguished from the difference in structures in the anterior region of the pronotum, B.dutraorum sp. nov. presents a bituberculated structure in the pronotum and a groove in the posterior region of the forehead carina. Geographical distribution. Brazil (Mato Grosso).
