Physodactylus brasiliensis Fleutiaux, 1892: 406 , 408; Schwarz, 1906: 311; Fleutiaux, 1940c: 168; Schenkling, 1927: 508; Blackwelder, 1944: 292. Redescription (male, Fig. 35A View FIGURE 35 ): Integument very shiny, head dark brown with frons lighter, antennomeres I-III reddish-brown, IV-XI dark brown; pronotum light yellowish-brown or ochre with posterior angles, anterior and posterior borders black; scutellum with borders darker, elytra light brown with surrounding area of punctures darker; ventral surface dark brown to black, except for the posterior part of prosternum, epipleura, femur and lateral border of ventrites 1-4 and ventrite 5 light brown; pilosity yellow. Total length 10.0-14.0 mm; elytral base 1.10-1.12x wider than prothorax, elytra 3.12-3.33x longer than pronotum. Frons with a triangular concave area, frontal carina produced; antenna ( Fig. 17A View FIGURE 17 ) reaching the base to apex of the posterior pronotal angles; antennomere IV-IX as long as wide; X 1.28x longer than wide; XI oval 1.75x longer than wide. Pronotum weakly convex ( Fig. 17B View FIGURE 17 ) 1.17-1.19x wider than long, lateral sides straight and roundly narrowed from posterior angle to anterior margin, posterior angles long, narrow and carinate; lateral carina nearly reaching the anterior margin, nearly entirely visible dorsally; disc with punctures umbilicate, 1-2 diameters apart, a little larger and denser on lateral and anterior borders; prosternal process ( Fig. 17C View FIGURE 17 ) without subapical tooth. Lamellae of pro- and mesotarsomere I a little smaller than the others, present on metatarsomere I. Elytra tapering apicad from humerus or anterior third, punctures of apical striae larger than those of the pronotal lateral border; elytral interstices weakly convex, smooth, sparsely punctate. Abdomen with ventrites 2-3 strongly concave laterally, with long decumbent setae on ventrites 2-4, a little shorter on ventrite 1. Pregenitalic segments and aedeagus covered with yellow to light-brown setae. Sternite VIII with posterior margin straight or emarginate medially, anterior sclerotization inverted V-shaped 0.28x the total width of sternite; sternite IX with apex acute.

Aedeagus ( Figs. 17E, F View FIGURE 17 ): Phallobase 0.49x the total length of aedeagus, 1.36x longer than wide, length ratio between lateroposterior and median parts 5.70; paramere with ventral surface predominantly membranous except for the lateral border and anterior margin sclerotized; penis with basal strut 0.27x its total length, articulated to the parameres by a strongly sclerotized process; ventral sclerite parallel-sided.

Holotype: [ Brèsil, Caraça, P. Germain, 2º semestre 1884], [ Physodactylus brasiliensis J Fleut. Type Brèsil], [Fltx. 1891], [Museum Paris ex Coll. R. Oberthur], [Type], [Lectotype], [ Physodactylus brasiliensis Fleut. J. Chassain det. 05], male ( MNHN).

Material examined. BRAZIL. Minas Gerais: Monlevade , 1 ex. ( MNHN) ; Caraça , 2 exs. ( MZUSP) ; Serra do Cipó , 1 ex. ( MZUSP) .

Distribution: BRAZIL. Minas Gerais: João Monlevade; Serra do Caraça; Serra do Cipó.

Remarks: The specimen with the Fleutiaux’s label has terminalia with light-brown setae and sides of penis more rounded. Physodactylus brasiliensis is distinguishable from the other species in its pattern color, the very shiny integument and the long and carinate posterior pronotal angles.
