Clypeus with lateral carinae extending backwards and posterior border of the frons with a groove in the shape of an arch marked by points. Pronotum mesoanteriorly without evident structure. Elongated scutellum, with parallel edges anteriorly and subtly rounded posteriorly ( Figure 5 (b)). Type material. The holotype is deposited at the MZSP, which provided a photo for analysis. Holotype . ‘135;//W. Zikán// ITATIAYA 700 m . / Est. Do Rio/ 2-vi-934; Bolbapium spn 2/ HOLÓTIPO ♂ / S. Ide det. 19 (red label); Bolboceras / lucidulum / Kl ./ P. Pereira det’ ( MZUSP ). Redescription Body size : Length: 5.34–8.27 mm . Width: 4.23–6.24 mm . Head : Lateral carinae of clypeus extending backwards ending at the edge of the canthus.Frons flat without projection; median region, between the lateral carinae of the clypeus marked by points that form an arch; posterior region is an arc-shaped groove marked by well-defined points. Pronotum : Without evident ornamentation. Scutellum : Elongated, almost rectangular, parallel edges anteriorly and subtly rounded posteriorly, with no evident punctuation. Male terminalia : In dorsal view, parameres completely separated, from the base to the apex, and laterally extended ( Figure 8 (j)). In lateral view, parameres are practically not visible ( Figure 8 (l)). Phallobase with two pointed projections, one on each side, morphologically resembling the genitalia of Bolbapium lucidulum and Bolbapium paralucidulum differing from the other species that have a single central projection. Sexual dimorphism : This species does not feature sexual dimorphism. Remarks: Ide and Martínez (1993) described the species based on three specimens collected in Rio de Janeiro : the male holotype , from Itatiaia, collected by W. Zikán; and two paratypes (females),one from Represa Rio Grande,collected by F.M.Oliveira,and the other from Galeão, collected by M. Alvarenga. The holotype and paratype collected in Galeão are deposited at the MZSP, and the paratype collected at the Represa Rio Grande is deposited at the DZUP. Differential diagnosis. Bolbapium sulcifrons is morphologically similar to B. lucidulum , B. matheusi sp. nov. , B. paralucidulum and B. quinquestriatum in not presenting the forehead with tubers and interocular carinae. However, it is easily differentiated by presenting an elongated scutellum. Geographical distribution. Brazil ( Bahia , Paraíba , Pernambuco and Rio de Janeiro ) . Non-type material. 32 specimens .
