Pronotal depression deep, divided by a prominent, more or less transverse, median tubercle reaching lateral margins of depression. Pronotum evidently rugose throughout, less so at sides near lateral carina. Antebasal carina interrupted at middle (subequal to twice width of carina), oblique towards lateral carina. Lateral carina slightly sinuous. Secondary carina straight, widely interrupted at middle, reaching lateral carina. Laterobasal carina not reaching posterior margin of prothorax. Prosternum ( Fig. 260) weakly raised, almost flat, with moderately coarse, shallow, sparse punctures; antecoxal furrow shallow, sinuous, strongly curved in front of procoxae, with developed, subtriangular prosternal projection at middle not interrupting furrow. Mesosternum with moderately coarse, shallow, irregularly sparse punctures, with deep, irregular, transverse impression near intercoxal process. Intercoxal process of mesosternum with longitudinal impression progressively deeper from apex to base, slightly swollen at lateral and apical margins, without lateroapical projections. Elytra about twice as long as wide across humeri; impressed along basal two thirds of interstria 2, convex at apical third; basal gibbosities weakly prominent; surface rugose from base to behind middle, more evidently at base, less so near suture. Sides slightly convergent apically from basal third. Anteapical tubercles ( Fig. 234) prominent, rounded, interstriae 3, 5, 7 and 9 feebly swollen. Wings with radial cell. Abdomen. Ventrite I with developed setiferous patch, varying from almost round to suboval, more evidently rounded at posterior half, and clothed with dense, erect, moderately long, yellowish pubescence; intercoxal process deeply grooved. Ventrite V emarginate at apex, lateroapical angles slightly projected, almost rounded. Pygidium ( Fig. 54) slightly wider than long, subconvex at anterior half, with short groove to fit elytra; apical margin rounded­truncate. Terminalia. Tergite VIII ( Fig. 73) as wide as long, subparallel at sides, rounded at apex; sternite VIII ( Fig. 87) convergent at sides, apical margin emarginate with distinct lobes, apodeme triangular and membranous; apodeme of sternite IX ( Fig. 101) 4.6 times as long as arms. Tegmen ( Fig. 115) rounded at apex. Aedeagus ( Figs. 138–141) with arc between apodemes; tectum( Fig. 139) curved at proximal margin, sides acuminate apically from middle; pedon( Figs. 138, 140) with body slightly curved, narrowed apically, apex weakly pigmented and acuminate; apodemes slightly curved. Internal sac about as long as aedeagus, spiculated medially; lateral membrane with pigmented rods; median sclerites strongly sclerotized and narrow ( Fig. 141). Female. Rostrum slightly shorter, 1.1–1.2 times as long as wide across base. Antennae shorter, exceeding middle of prothorax; segment XI longest (II = 0.5–0.7; III = 0.4–0.7; IV = 0.5–0.8; V = 0.4–0.8; VI = 0.4–0.6; VII = 0.4–0.7; VIII = 0.3–0.4; IX = 0.5–0.8; X = 0.4–0.7; XI = 0.6–0.9). Elytra more convex. Pygidium strongly impressed at middle near apex. Ventrite V less emarginate at apex. Terminalia similar to that of  P. mixtus, differing by tergite VIII emarginate at apex; gland of spermatheca not observed. Measurements in mm, male/female, respectively. TL = 10.7–22.8/13.3–20.7; RL = 1.4–4.1/1.6–2.7; RAW = 1.3–2.7/1.7–2.5; RBW = 1.1–2.2/1.4–2.1; HW = 1.7–3.2/ 2.0–3.0; DSO = 0.5–1.9/0.6–0.9; MLO = 0.9–1.8/1.1–1.7; PL =3.0–6.7/3.5–5.8; PW = 2.8–5.7/3.4–5.3; EL = 6.8–14.8/8.8–13.7; EW = 3.4–6.8/4.2–6.8.  Remarks   P. callosusis the sister group of  P. rugicollis, by having a rounded tubercle at halfway of elytral apical declivity, between the interstriae 3 and 9 (31 3), and lateral membrane with pigmented rods in the distal region of the internal sac (43 1).  P. callosusdiffers by the olivaceous­green scales of the dorsal vestiture, and the prosternal furrow with a developed subtriangular projection at middle. In  P. rugicollis, the scales are brownish, and the prosternal furrow narrow with a tiny median projection.   Ptychoderes callosusis similar to  P. brevismainly by the dorsal vestiture with olivaceous­green scales, differing by the almost flat prosternum with moderately coarse, shallow, sparse punctures; antecoxal furrow from slightly deep to shallow, sinuous, strongly curved in front of procoxae, and with a developed, subtriangular projection at middle; elytra with basal gibbosities weakly raised, anteapical tubercles prominent, and interstriae 3–9 slightly swollen. In  P. brevis, the prosternum is raised with dense, deep, coarse punctures; the antecoxal furrow straight, deep, without projection at middle; and the elytra with prominent basal gibbosities, without anteapical tubercles and interstriae not swollen.   Typematerial   Threefemale syntypesfrom Cayenne, French Guiana( MNHN) were examined.
