Diagnosis

Frons with transversal carina with tubercle formation on each side. Lower parts of clypeo-frontal carina much higher than anterior clypeal carina. Pronotum mesoanteriorly with a central bituberculated struture and a distinct lateral tubercle at each side of central struture. Depression marked by points behind the central projection ( Figure 3 (d)).

Etymology. The new name is proposed after Hermann (also Germano) Lüderwaldt (also Luederwaldt), a Pomeranian entomologist established in Brazil in the beginning of the twentieth century, who among many other important works reviewed the Brazilian bolboceratines and described several species.

Type locality. Tangará da Serra, Mato Grosso, Brazil.

Description

Body size: Length: 5.40–7.59 mm. Width: 4.06–6.05 mm. Head: Lower parts of clypeofrontal carina much higher than anterior clypeal carina. Frons presents a slightly curved transversal carina with tubercle formation on each side, which is not very apparent; region between the clypeus and the carina with fine points. Pronotum: Pronotum mesoanteriorly with a central bituberculated struture and a distinct lateral tubercle at each side of central struture. Depression marked by points behind the central projection. Disc sides with sparse distributed points, unevenly distributed. Ventral region of the thorax: Central region of the metaventrite with a few setae that are more concentrated in the posterior part, near the lower margin without 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, parallel parameres, meeting at the apex ( Figure 7 (g)). 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, almost reaching the parameres ( Figure 7 (i)). Sexual dimorphism Males present the posterior region of the clypeus with fine and distinct punctuation, setae and carinae absent, while females have a rough and carenaded clypeus surface, with four setae in the posterior region. Remarks: This is the species usually named ‘ Bolbapium sculpturatum ’ in most collections. As we had no evidence that Odontaeus sculpturatus Mannerheim, 1829 is truly a species of Bolbapium , we here provide a new name for this species. So, the name Odontaeus sculpturatus Mannerheim, 1829 is considered a species inquirenda.

Differential diagnosis. Bolbapium luederwaldti sp. nov. is morphologically similar to B. baeri , B. furtadoi sp. nov., B. limeirai sp. nov., B. minutum and B. quadrispinosum in presenting the forehead with a transverse carina interconnected by tubercles. However, it is easily distinguished by presenting a bituberculated projection with a flat surface and lateral tubercles on the pronotum.

Geographical distribution. Brazil (Alagoas, Distrito Federal, Espirito Santo, Goiás, Maranhão, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, Rondônia, Santa Catarina and São Paulo) and Argentina (Buenos Aires) .
