(Figures 3 (c), 7(d), (e), (f), 16(b))
Diagnosis
Lower parts of clypeo-frontal carina much higher than anterior clypeal carina; mesoanterior pronotal structure bituberculated, well emarginated, tubercle on each side of the central structure (Figure 3 (c)).
Etymology. Named for Dr Sergio Ide, Brazilian scarabaeoidologist, who reviewed the genus Bolbapium in his MSc thesis back in 1992.
Type locality. Recanto das Siriemas, Cuiabá, Mato Grosso, Brazil.

Description
Body size: Length: 5.70–6.01 mm. Width: 4.41–4.69 mm. Head: Lower parts of clypeofrontal carina much higher than anterior clypeal carina. Frons presents an arc-shaped carina that connects with clypeo-frontal carina; region between the carina and the clypeus with a weak and not very evident score. Antenna with the last three antennomeres with globular shape compared with the other species (Figure 2 (c)). Pronotum: Bituberculated structure, well emarginated, and a tubercle on each side of the central structure. Ventral region of the thorax: Central region of the metaventrite with a few unevenly distributed setae. Elytron: There are setae in the apical region of the external dorsal margin of the elytron (quantity varies among individuals). Male terminalia: In dorsal view, parameres are found together, separating slightly at the apex (Figure 7 (d)); in lateral view, curved parameres forming an angle of almost 45°; posterior margin with slightly curved projection and rounded apex (Figure 7 (f)). Sexual dimorphism: This species does not feature sexual dimorphism. Remarks: The primary type is deposited at the CEMT.
Differential diagnosis. Bolbapium sergioidei sp. nov. is morphologically similar to B. dutraorum sp. nov. and B. striatopunctatum in presenting the forehead with a transverse carina without tubercle formation on each side. However, it is easily distinguished by the difference in structures in the anterior region of the pronotum: B. sergioidei sp. nov. has a strongly bituberculated structure, in addition to the upward-projected clypeus.
Geographical distribution. Brazil (Mato Grosso); Bolivia (Santa Cruz); Argentina (Corrientes and Santiago del Estero), Paraguay (Asunción and Cordillera).
