description: Physodactylus foveatostriatus Fleutiaux, 1892   
 (Figs. 20 H-L, 35H)   
 Physodactylus foveatostriatus Fleutiaux, 1892: 406; Schwarz, 1906: 311; Fleutiaux, 1940c: 164, 166; Blackwelder, 1944: 292.   
 Redescription (male, Fig. 35H): Integument bright; dark brown to black with prothorax orange to reddish-brown; legs colored as elytra or with femur reddish-brown; pilosity brown. Total length 11.5-16.0 mm; elytral base 1.0-1.03x as wide as prothorax, elytra 2.7-3.0x longer than pronotum. Frons concave, disc of anterior part of head strongly convex, frontal carina weakly impressed; antenna (Figs. 20H, 23A) reaching the posterior third of pronotum; antennomere IV 1.22x wider than long, V 1.47x wider than long, VI-X 1.25-1.37x wider than long; XI oval 1.3x longer than wide. Pronotum (Fig. 20I) 1.23-1.34x wider than long, lateral sides nearly straight to rounded convergent from posterior angles to anterior margin; anteromedian margin weakly produced; posterior angles elongate, convex, parallel; lateral carina complete weakly impressed, dorsally visible only on posterior half; disc with punctures 2-3 diameters apart, a little larger and denser on lateral and anterior borders; prosternal process (Fig. 20J) with a subapical tooth. Lamellae of pro- and mesotarsomeres I a little smaller than the others, present on metatarsomere I. Elytra parallel-sided on anterior 2/3 then tapering to apex, apex usually dehiscent; striae with a single row of punctures; interstices flattened, scarcely punctate, weakly rugose; apical striae with punctures about 2 times larger than those of pronotal lateral border. Abdomen with ventrites 2-3 slightly concave laterally, ventrite 1 punctate, covered with fine setae about 1/5 as long as those of ventrite 2, setae longer and sparser on marginal plates; ventrites 2-4 with setae moderately long, decumbent, sparser on marginal plates. Pregenitalic segments and aedeagus covered with stout dark-brown setae. Sternite VIII with lateroposterior sclerotizations separate or approximated medially; posterior margin straight, anterior sclerotization 0.3-0.4x the total width of sternite; sternite IX with apex rounded.   
 Aedeagus (Figs. 20K, L): Phallobase 0.4x the total length of aedeagus, 0.9-1.0 as long as wide, length ratio between lateroposterior and median parts 11.8-15.0; paramere with ventral surface weakly sclerotized, anteromedian margin with a linear sclerotization directed anteriad; penis with basal strut 0.2x times its total length, articulated to the parameres by a sclerotized short process or by a translucent membrane; ventral sclerite elongate, widened apicad.

 Remarks: Physodactylus foveatostriatus is distinguished by its large punctures of the elytral striae, a unique character among Physodactylus species. This autapomorphy combined with the shape of elytra, more tapered and dehiscent at apex, the abdominal pilosity pattern and the shorter phallobase easily separate this species from the morphologically closest species, which are P. fischeri, P. asper and P. chassaini.
