Description

Body size: Length: 5.68–6.55 mm. Width: 4.19–4.98 mm. Head: clypeal carina extending to the mid-frontal forming slight angulation; frons without structures; every surface with sparse points, unevenly distributed. Pronotum: anterior region of the disc with little developed tubercle, almost bidentate. The entire pronotum surface with sparse points, greater concentration on the sides of the disc and unevenly distributed. Ventral region of the thorax: Central region of the metaventrite with a few unevenly distributed setae. Male terminalia: In dorsal view, apparently short parameres with the approximate base and the apex greatly separated ( Figure 11 View Figure 11 (a)). In lateral view, elongated parameres and posterior margin as long as the parameres ( Figure 11 View Figure 11 (c)). Sexual dimorphism: Males have a smooth surface and setae are absent, while females have up to four setae in the posterior region of the clypeus and a carenaded clypeus surface. Remarks: The primary type is deposited at the CEMT.

Differential diagnosis. Bolbapium matheusi sp. nov. is morphologically similar to B. lucidulum , 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 slight sinuosity in the anterior region of the pronotum.
