Diagnosis

Frons with tubercles connected by transversal carina between the eyes. Pronotum mesoanteriorly with robust pair of tubercles, connected at base and separate middle and apex region, behind the structure there is a depression in which the median groove begins ( Figure 4 (a)).

Neotype. ‘ BRASIL: São Paulo./ Jaboticabal. Campus/ FCAV-UNESP, 21°14 ʹ 25’S/ 48° 17 ʹ 22”O, 605 m. / outubro de 2013. Atraído / por luz. Noite. HL Rainho. ♂ ” ( CEMT 74829 ).

Redescription

Body size: Length: 4.32–6.16 mm. Width: 3.33–4.84 mm. Head: Frons with interocular tubercles connected by transversal carina; region between the frons and the clypeus with slope and weak points. Pronotum: Bituberculated structure split in half at the anterior part of the disc; region immediately lateral to the concave projection; behind the projection there is a depression in which the median groove begins. Disc sides with a few points unevenly distributed. Ventral region of the thorax: Metaventrite with a few unevenly distributed setae. Elytron: There are setae in the apical region of the external dorsal margin of the elytra (quantity varies among individuals). Male terminalia: In dorsal view, parallel and separate parameres ( Figure 8 (a)). Parameres slightly curved in lateral view, forming an approximate angle of 45° in relation to the phallobase; posterior margin in lateral view with pointed and curved projection ( Figure 8 (c)). Sexual dimorphism: Males have the anterior margin of the clypeus projected forward, the width is smaller, the setae are absent and the tubercles and central structure are more robust, while the females have the clypeus as wide as long and in the posterior region of the clypeus up to four setae, rough and carenaded clypeus surface, and the projection of the pronotum is lower compared to males.

Designation of type material. It was confirmed that the type of Bolbapium quadrispinosum was lost in the fire that occurred at the National Museum, Rio de Janeiro, in 2018, therefore, for confirmation of the taxon and so there are no further problems of identification,we propose to designate a neotype for the species. The specimen being proposed as a neotype originally belongs to the CEMT,and comes from the location closest to the type locality of the species. It will be deposited at the National Museum, Rio de Janeiro.

Differential diagnosis. Bolbapium quadrispinosum is morphologically similar to B. baeri , B. furtadoi sp. nov., B. limeirai sp. nov., B. luederwaldti sp. nov. and B. minutum in presenting the forehead with a transverse carina interconnected by tubercles. However, it is easily distinguished from the other species because presents the structure of the pronotum split in the middle.

Geographical distribution. Brazil (Alagoas, Bahia, Espirito Santo, Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais and São Paulo) and Bolivia (Santa Cruz) .
