( Figures 10 (g), (h), (i), 17)

Diagnosis

Frons with formation of poorly developed interocular tubercles and the anterior part of the pronotum with little elevated, almost bidentate tubercle.

Description

Body size: Length: 6.20–7.14 mm. Width: 4.84–5.59 mm. Head: Clypeal carina with three tubercles on an equal level. Frons with poorly developed interocular tubercles, not connected by carina; region between the tubercles almost flat and with few points. Pronotum: Anterior region of the pronotum with little elevated tuber, almost bidentate, which can be more or less developed; depression marked by pointsbehind the tubercle. Male terminalia: In dorsal view, extremely short and flat parameres, posterior margin going beyond the apex of the parameres ( Figure 10 (g)). In posterior lateral margin view with curved projection forming an approximate 45° angle towards the parameres ( Figure 10 (i)). Sexual dimorphism: This species does not feature sexual dimorphism. Remarks: The primary type is deposited at the CEMT.

Differential diagnosis. Bolbapium santanaorum sp. nov. is morphologically similar to B. borgmeieri , B. boillyi sp. nov., B. caesum , B. howdeni , B. modestum , B. parcepunctatum and B. sampaioorum sp. nov. in not presenting the transverse carina forehead interconnecting the interocular tubercles. However, it is easily differentiated by presenting a bituberculated projection.In addition,it is only possible to separate the species of Bolbapium parcepunctatum for male aedeagus and geographic distribution; see the Remarks on B. parcepunctatum for more information.

Geographic distribution. Brazil (Maranhão, Minas Gerais, Distrito Federal, Goiás, Mato Grosso, Paraná and São Paulo) .
