description: Schmidarius Santos-Silva, Heffern, Botero and Nascimento, new genus   
 Type species. Schmidarius kondratieffi Santos-Silva, Heffern, Botero and Nascimento, sp. nov., present designation.   
 Description. Female. Head not wider than prothorax; frons without projections, transverse. Gena distinctly longer than lower eye lobe. Antennal tubercles distant from each other. Eyes not divided; posterior margin of eyes distant from base of prothorax; upper eye lobes narrow, distance between them distinctly greater than width of one lobe. Antennae 11-segmented, not reaching elytral apex; scape without basal curvature, without apical cicatrix, shorter than antennomere III; pedicel much shorter than antennomere III and scape; antennomere III distinctly tumid, with dense erect setae throughout; antennomere IV shorter than III; antennomeres IV–XI cylindrical; antennomeres IV–VIII with long, erect, sparse setae on inner surface; antennomere XI not stinger-shaped. Prothorax proportionally short, transverse, about as wide anteriorly as posteriorly; sides without tubercles or strong gibbosities. Prosternal process distinctly narrow centrally, about 0.2 times width of procoxal cavity. Mesoventral process with flap on each side near apex. Elytra not distinctly widened from base to apex; humerus rounded, not projected; humeral carina well marked from base to apex; area between humeral carina and epipleural margin without carinae, without whitish pubescence contrasting with that on dorsal surface, gradually more distinctly visible in dorsal view from basal quarter; dorsal carina from well-marked to slightly distinct; apex individually rounded, without sutural projection; sutural area without long and erect setae. Metatarsomere I slightly shorter than II–III together; tarsal claws not divided basally, with inner tooth moderately shorter than outer one.   
 Etymology. The new genus is named in honor of Herbert Schmid (Austria), for his frequent assistance with information and photographs of the type specimens deposited in his collection; the suffix “-arius” is Latin, meaning “belonging to”. Masculine gender.   
 Remarks. Schmidarius gen. nov. is rather similar to Lamacoscylus Martins and Galileo, 1991, from which it differs by the antennomere III distinctly tumid and with long, dense and erect setae throughout. In Lamacoscylus the antennomere III is cylindrical, similar to the other antennomeres, and the erect setae are much sparser. It differs from Malacoscylus Thomson, 1868 by the antennomere III not much longer than IV (much longer in Malacoscylus); from Sybaguasu Matins and Galileo, 1991 by the scape not curved basally, and vertex not concave (scape curved and vertex concave in Sybaguasu); from Themistonoe Thomson, 1864 by the pronotum without distinct gibbosities, and elytra with dorsal carina (pronotum with anterolateral gibbosities, and elytra without carina in Themistonoe); and from Cacupira Martins and Galileo, 1991 by the sutural apex not projected (projected in Cacupira).   
 Martins and Galileo (1991) did not describe the shape of the antennomere III in the original description of Lamacoscylus. According to them, the setae on antennomere III are denser in females than in the males of this genus. However, male and female of L. humilis have the antennomere III nearly identical. Therefore, we believe that the shape of the antennomere III in S. usingeri (see photograph in Bezark 2020) and S. kondratieffi is not sexually dimorphic.   
 Species included. Schmidarius kondratieffi, sp. nov.; S. usingeri (Linsley, 1935); S. grisescens (Gahan, 1892); S. flavescens (Gahan, 1892).
