Diagnosis

Clypeo-frontal carina with central tubercle very high and detached, usually at least as high, above carina, as lower parts of the carina itself. Pronotum mesoanteriorly with prismatic structures in females and mammiliform structures in males; at most a lateral indistinct rounded elevation at each side ( Figure 3 View Figure 3 (e)).

Neotype: ‘ BRASIL: MS, Corumbá / Passo do Lontra, FIT/ ii.1999, V. Lopes leg’. ♂ ( CEMT 74144 ).

Redescription

Body size: Length: 3.98–7.52 mm. Width: 3.07–5.60 mm. Head: Clypeo-frontal carina with central tubercle very high and detached, usually at least as high, above carina, as lower parts of the carina itself. Canthus presents different types of punctuation, some strong and some weak. The frons presents a slightly arched transversal carina with tubercle formation on each side; the region between the clypeus and the frons with slope and points randomly distributed; region behind the frontal carina marked by circular and oval points. 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: Prismatic or mammiliform structures in the anterior part of the disc. Disc sides with sparsely distributed points, unevenly distributed. 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 elytra (quantity varies among individuals). Male terminalia: Parameres not seen dorsally ( Figure 7 View Figure 7 (j)); in lateral view completely curved, at an angle of approximately 90° in relation to the phallobase ( Figure 11 View Figure 11 (l)). Sexual dimorphism: Females have a prismatic structure in the anterior region of the pronotum, while males have this mammiliform structure, which can be very or little developed in both. Remarks: Luederwaldt (1931) described Bolbapium minutum and designated as type a specimen collected by W. Melzer in Porto Murtinho, Mato Grosso do Sul. In the same work he described Bolbapium bigibbosum based on two specimens, also collected by Melzer in Porto Murtinho, Mato Grosso do Sul. The suspicion of synonymy between the two species was raised by Sergio Ide in his master’s dissertation. From an examination of the genitalia of both species, Ide confirmed that all specimens of B. minutum are females and B. bigibbosum males, in addition to the coincidence of geographical distribution; however, the work has not been published. More specimens were dissected and analysed to support this previously proposed hypothesis. This leads us to conclude that the two names are synonymous. As both names have been proposed in the same work, the name Bolboceras minutum is here chosen as senior synonym because it represents the size of the specimens, both male and female, while the name B. bigibbosum refers to a character that is found only in males. Besides, Ide (1992) had already suggested (while not validly published) the use of minutum instead of bigibbosum and, in consequence, most Brazilian collections already bear this name as the valid name for this species.

Designation of type material. It was confirmed that the type of Bolbapium minutum was lost in the fire that occurred at the National Museum, Rio de Janeiro, in 2018. According to Ide the type of Bolbapium bigibbosum is in the MZSP; however it was not found. Therefore, for confirmation of the taxon and so there are no further problems of identification, we propose the designation of a neotype for species. The specimen being proposed as a neotype originally belonged 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 minutum is morphologically similar to B. baeri , B. furtadoi sp. nov., B. limeirai sp. nov., B. luederwaldti sp. nov. and B. quadrispinosum in presenting the forehead with a transverse carina interconnected by tubercles. However, it is easily distinguished from the other species by presenting the mammiliform or prismatic projections.

Geographical distribution. Brazil (Bahia, Espirito Santo, Goiás, Maranhão, Mato Grosso do Sul, Mato Grosso, Paraná, Santa Catarina and São Paulo); Argentina (Catamarca and Chaco); Bolivia (Santa Cruz); Paraguay (Amambay, Caazapá, Canindeyú, Concepción and Villarica) and Uruguay .

Non-type material. 180 specimens.
