Diagnosis
Frons without interocular tubercles between eyes. Clypeus with lateral carinae extending backwards; posterior border of the frons with transverse groove. Pronotum mesoanteriorly without evident structures and pronotum with serrated lateral margins ( Figure 5 View Figure 5 (d)).
Type material. It was possible to analyse one of the types during the curator’s stay at the BMNH in Cuiabá; photos of the specimen were taken during this period. The other types are deposited at the MNHN, which provided photos of the material. Therefore, we here designate a lectotype.
Lectotype. ‘Para-/guay; MUSÉUM PARIS/ 1938/ COLL. A. BOUCOMONT; SYNTYPE [red rectangular label]; SYNTYPE / Bolbapium / quinquestriatum/ ( Boucomont 1932)’ ( MNHN / EC10573).

Redescription
Body size: Length: 8.11–9.47 mm. Width: 6.28–7.43 mm. Head: Clypeus opaque, with distinct punctuation; sides wider than the central part; clypeal carina with three tubercles, the lateral ones being slightly higher than the middle one; lateral carinae extending backwards ending at the edge of the canthus. Canthus wide compared to other species of the genus, with strong and evident punctuation. Frons flat and without projections, punctuation more concentrated in the anterior region, between the clypeal carinae; other parts with sparse points, distributed unevenly; posterior region of the frons with transverse groove. The last three antennomeres of the antenna, which form the antennal club, have a globular shape, compared to the other species ( Figure 2 View Figure 2 (c)).
Pronotum: Serrated side margin and with a row of ventral setae. Without evident structures. Ventral region of the thorax: Metaventrite convex in the central region and with a median groove that follows from the apex the base of the metaventrite, the base being wider than the apex; region where the median groove starts higher than the others, projected upwards; metaventrite surface with setae, except for a small region near the lower margin. Male terminalia: Elongated, parallel and symmetrical dorsal view ( Figure 9 View Figure 9 (a)); in lateral view, longitudinal parameres to the phallobase ( Figure 9 View Figure 9 (c)). Sexual dimorphism: This species does not feature sexual dimorphism.
Designation of type material. Bolbapium quinquestriatum was described based on a series type; the author did not mention how many specimens were studied and did not designate the holotype. Currently the types are deposited at the MNHN and BMNH and have been examined, respectively, by photos and in person. We propose to designate the lectotype for the species to ensure the fixation of the specific name in the best available specimen, in terms of good condition and development of any diagnostic chacacters subject to allometry.
Differential diagnosis. Bolbapium quinquestriatum is morphologically similar to B. lucidulum , B. matheusi sp. nov., B. paralucidulum , B. quinquestriatum and B. sulcifrons in not presenting the forehead with tubercles and interocular carinae. However, it is easily differentiated by presenting a serrated pronotum edge.
