( Figs. 27C, D ; 35N )

Physodactylus oberthuri Fleutiaux, 1892: 406 , 407; Schwarz, 1906: 311; Schenkling, 1927: 508; Fleutiaux, 1940c: 168; Blackwelder, 1944: 292; Chassain, 2005: 68.

Redescription (male, Fig. 35N ): Integument very bright, dark brown with elytra lighter; pilosity brown. Total length 12.5 mm; elytral base 0.97x as wide as prothorax, elytra 2.7x longer than pronotum. Frons with a circular protuberance medially; frontal carina produced anteriorly; antenna nearly reaching the half length of pronotum; antennomere IV-X 1.2-1.3x wider than long; XI oval. Pronotum 1.18x wider than long, lateral sides rounded from posterior angles to anterior margin, strongly narrowed on anterior angle, anteromedian margin strongly produced; posterior angles elongate, convex, parallel; lateral carina complete, prominent, nearly entirely visible dorsally; disc and lateral margin with punctures very small and weakly impressed, 4-6 diameters apart, larger on anterior margin, homogenously distributed. Lamellae of pro- and mesotarsomeres I smaller than the others, present on metatarsomere I. Elytra rounded on anterior 2/3 then tapering to apex; striae with a row of punctures larger than those of lateral pronotal border, interstices slightly convex, rugose, sparsely punctate. Abdomen with ventrites 2-3 concave laterally, with setae moderately long and decumbent on ventrites 2-5, ventrite 1 with setae a little shorter than and as dense as those of ventrites 2-5. Pregenitalic segments and aedeagus covered with brown setae. Sternite VIII with posterior margin emarginate medially, anterior sclerotization curved 0.57x the total width of sternite; sternite IX with apex acute.

Aedeagus ( Figs. 27C, D ): Phallobase 0.49x the total length of aedeagus, 1.32x longer than wide, length ratio between lateroposterior and median parts 3.7; paramere with ventral surface partly membranous, except for the lateral margin and the anterior margin sclerotized; anteromedian sclerotized margin approximate at middle; penis with basal strut 0.34x its total length, articulated to the parameres by a translucent membrane; ventral sclerite tapering apicad.

Fr. 1892, p. 407, t. 8 f. 2 Collection FLEUTIAUX], [ Physodactylus oberthuri J Fleut. type], [ Physodactylus oberthuri J Fleut. type, Brèsil (Coll. Oberthur)], [Museum Paris, ex. Coll. R. Oberthur], [Lectotype], [ Physodactylus oberthüri Fleutiaux, J. Chassain det. 05], male, (MNHN).

Distribution: BRAZIL.

Remarks: The apical part of the prosternal process was not examined. Physodactylus oberthuri is similar to P. niger and P. tuberculatus sp. nov. in prothoracic shape. It is most similar to this latter in the shape of aedeagus, very bright integument and pronotal punctation homogenously distributed. It differs from both species manly in its brown setae and the very fine pronotal punctation.
