Physodactylus fleutiauxi Chassain, 2005: 68 . Redescription (male, Fig. 35G View FIGURE 35 ): Integument bright, evenly black; pilosity yellow. Total length 13.5-15.5 mm; elytral base 1.0-1.1x wider than prothorax, elytra 2.7-2.8x longer than pronotum. Frons concave to convex, frontal carina not or slightly produced; IEP 0.21-0.25; antenna reaching the anterior third of pronotum; antennomere IV 1.2x wider than long, V-X 1.8x wider than long, XI oval 1.2x longer than wide. Maxilla with galea covered with fine and spiniform setae. Pronotum convex 1.3x wider than long, parallel on posterior third then straight or roundly convergent to anterior margin; anteromedian margin slightly produced anteriad; posterior angles short, convex, parallel; lateral carina evenly prominent to anterior margin; dorsally visible only on posterior third; disc with punctures medium size homogenously distributed 0.5-1.0 diameters apart, smaller and denser on anterior margin, denser on lateral border; prosternal process without subapical tooth. Lamellae of pro- and mesotarsomeres I very small, absent on metatarsomere I. Elytra parallel-sided on anterior 2/3 then tapering to apex; apex usually with a very small sutural spine; striae deeply impressed, with three rows of punctures, punctures glabrous on the median row, smaller and bearing a small seta on the lateral row; interstices convex, smooth and glabrous; apical striae with punctures smaller than those of pronotal lateral border and as large as those of elytral base. Abdomen with ventrites 1-4 strongly and evenly convex, ventrite 1 evenly pilose with short decumbent setae, 2-4 with long semi-erect setae. Pregenitalic segments and aedeagus covered with stout yellow setae. Sternite VIII subrectangular, posterior margin straight, anterior sclerotization 0.5x the total width of sternite; sternite IX tapered to apex.

Aedeagus: Phallobase 0.5x the total length of aedeagus, 1.6x longer than wide, length ratio between lateroposterior and median parts 4.5-6.1; ventral surface of paramere with the lateral half and anterior margin sclerotized; penis with basal strut 0.2-0.3x its total length, articulated to the parameres by a strongly sclerotized process; ventral sclerite parallel-sided.

Holotype: [ Brésil, (Mato Grosso), 14°15’50.80”S, 59°14’02.05”W, Chapada dos Parecis, 30 km N d’Uirapuru ], [01/ 15-12-2000, A. Foucart]. [Holotype], [ Physodactylus fleutiauxi , Holotype, J. Chassain det. 04], male ( MNHN). GoogleMaps

Distribution: BRAZIL. Mato Grosso: Chapada dos Parecis.

Remarks: Physodactylus fleutiauxi has aedeagus similar to that of P. sulcatus , differing only in its slender phallobase. Physodactylus fleutiauxi differs also from that species in its body evenly black, pronotum weakly convex with lateral carina complete and pronotal punctation distinctly different from the finer and sparser hypomeral punctation.
