description: Physodactylus asper sp. nov.   
 (Figs. 16 A-D, 34Q)   
 Etymology: From Latin, asper = rough; alluding to the rugose and coarsely punctate elytra.   
 Description (male, Fig. 34Q): Integument bright; head, antennae, legs and ventral surface black, pronotum reddish-brown, elytra dark brown with epipleura lighter; one specimen with pterothorax and ventral abdomen reddish-brown on the median longitudinal line; pilosity brown. Total length 8-10 mm; elytral base 1.0x as wide as prothorax, elytra 3.0-3.2x times longer than pronotum. Frons slightly concave, frontal carina weakly impressed; antenna (Fig. 16A) reaching the posterior third of pronotum, antennomere IV as wide as long, V-X 1.17-1.20x wider than long; XI oval 1.5x longer than wide. Pronotum (Fig. 16B) 1.20-1.26 wider than long, with lateral sides nearly straight to rounded convergent from posterior angles to anterior margin; anteromedian margin weakly produced; posterior angles short, convex, parallel; lateral carina prominent nearly entirely visible dorsally, complete; disc with punctures 2-3 diameters apart, larger and denser on lateral and anterior borders; prosternal process without subapical tooth. Lamellae of pro- and mesotarsomeres I smaller than the others, absent on metatarsomere I. Elytra tapering to apex from anterior third or subparallel on anterior 2/3 then tapering to apex; striae with large and small dense punctation, striae indistinct on apical region where the punctation is mixed and coalescent; interstices convex and rugose, scarcely punctate; apical striae with punctures larger than those of pronotal lateral border. Abdomen with ventrites 2-4 strongly concave laterally; ventrite 1 densely punctate with minuscule fine setae, lateral border smooth with a few long, very fine setae; ventrites 2-4 punctate as ventrite 1 with long, decumbent and semi-erect fine setae, lateral border smooth with a few finer setae. Pregenitalic segments and aedeagus covered with stout dark-brown setae. Sternite VIII emarginate posteromedially, anterior sclerotization 0.62x times the total width of sternite; sternite IX with apex rounded.   
 Aedeagus (Figs. 16C, D): Phallobase 0.49x the total length of aedeagus, 1.26x longer than wide, length ratio between lateroposterior and median parts 34; paramere with ventral surface nearly entirely sclerotized with anteromedian margin distinct; penis with basal strut 0.19x its total length, articulated to the parameres by a sclerotized short process; ventral sclerite linear.   
 Holotype: [DPTº ZOOL, UF-PARANÁ], [MARACÁS, BRAZIL, BAHIA, 19/11/1965, F.M. Oliveira leg.], male (DZUP).   
 Paratypes: Same labels as holotype, 2 exs. (DZUP); idem, 1 ex. (MZUSP).   
 Distribution: BRAZIL. Bahia: Maracás.   
 Remarks: Physodactylus asper sp. nov. is similar to P. fischeri in the shape of prothorax, brown pilosity and the punctation and roughness of elytra, differing from this species in its smaller size, longer antenna, weaker impressed frontal carina, lateral pronotal carina complete, pilosity pattern of the abdominal ventrites, aedeagus with parameres more extensively sclerotized ventrally and articulated to penis through a sclerotized process, basal struts shorter and wider and median part of phallobase shorter.
