Male. Vestiture ( Fig. 225 View FIGURES 221–227 ): pale dorsal vitta with dense, appressed, whitish scales intermingled with decumbent light­brown to pale­light­brown scales, denser on rostrum, head and elytral interstriae 3 and 4; apical two thirds of elytra with sparse, suberect, fusiform, light­brown scales. Pygidium with predominance of brownish scales. Ventral body surface and legs with appressed, dense, yellowish­white scales except medially with sparse, blackish­brown pilosity; sides of prosternum, below lateral carina, with continuous dark vitta of blackish­brown scales. Sides of mesosternum with wide glabrous vitta. Anterior angles of ventrites III–V with small dark spot of dense, blackish­brown scales. Mesepisternum with shallow setigerous punctures each provided with a brownish scale, and becoming almost inconspicuous in mesepimera, metepisterna, and sides of metasternum and ventrites. Outer surface of meso­ and metafemora with strip of blackish­ brown scales.

Rostrum 1.3–1.8 times as long as wide across base; weakly depressed between carinae. Distance between scrobe and eyes from slightly shorter to slightly longer than maximum width of eye. Sides looking tricarinate due to careniform upper margin of scrobe; upper carina short not reaching scrobe, lower carina elongate, suboblique, reaching scrobal margin. Scrobes careniform at dorsal margin; extension wide, slightly deep with deep distal pit slightly wider than extension. Mentum sparsely, finely punctate, weakly impressed at sides, and shallowly grooved at apical margin. Gula with sparse, fine punctures. Frons almost flat, not impressed near ocular margin, with prominent carinae. Head elongate behind eyes; vertex almost flat.

Antennae ( Fig. 225 View FIGURES 221–227 ) from short, exceeding the middle of prothorax, to about as long as body, reaching apical ¼ of elytra. Segments II to VII increasing in length, remaining decreasing; IX 3 times as long as X; XI almost twice as long as X (II = 0.3–2.0; III = 0.3–2.6; IV = 0.3–3.3; V = 0.2–3.8; VI = 0.2–4.1; VII = 0.2–4.2; VIII = 0.1–3.6; IX = 0.3–2.9; X = 0.3–0.8; XI = 0.5–1.4).

Prothorax ( Figs. 225 View FIGURES 221–227 , 250 View FIGURES 239–250 , 262 View FIGURES 251–262 ) longer than wide, converging anteriorly from antebasal carina. Longitudinal pronotal depression deep, more so behind median tubercle, this almost rounded, weakly prominent, flat on top, not reaching margins of depression. Rugae short, weakly prominent, restricted inside depression, always more evident behind tubercle. Antebasal carina interrupted at middle (at least three times width of carina), curved towards lateral carina. Secondary carina sinuous, widely interrupted at middle, not reaching lateral carina. Laterobasal carina not reaching posterior margin of prothorax. Prosternum ( Fig. 262 View FIGURES 251–262 ) almost flat, with scarce, almost inconspicuous, fine punctures; antecoxal furrow vestigial and curved. Intercoxal process of prosternum at same level of prosternum. Mesosternum almost flat, dull, not punctured; anterior groove shallow. Intercoxal process of mesosternum with shallow, longitudinal groove, swollen and declivous at lateral and apical margins, with well developed lateroapical projections. Anterior groove of metasternum vestigial. Elytra 2.3 times longer than wide across humeri, flattened between suture and interstriae 3 at basal 3/4; basal gibbosities inconspicuous; surface weakly rugose at basal 1/5. Sides converging apically from basal third. Epipleura with shallow, short groove at base. Apex ( Fig. 233 View FIGURES 228–238 ) looking truncate due to subtransverse, prominent anteapical tubercles, interstriae 3–9 not swollen. Wings without radial cell.

Abdomen. Ventrite I with central, developed, rounded setiferous sex patch clothed with shining brown pilosity; groove of intercoxal process vestigial. Ventrite V not impressed on disk, slightly emarginate at apical margin. Pygidium wider than long, subconvex at anterior half, with short groove to fit elytra, truncate at apical margin.

Terminalia. Tergite VIII ( Fig. 77 View FIGURES 70–84 ) wider than long, subparallel­sided, apical margin almost rounded; sternite VIII ( Fig. 91 View FIGURES 85–112 ) almost rounded at sides, apical margin strongly emarginated forming large, well defined lobes, apodeme triangular and sclerotized; apodeme of sternite IX ( Fig. 105 View FIGURES 85–112 ) 3.2 times as long as arms. Tegmen ( Fig. 119 View FIGURES 113–126 ) obliquely truncate at apex. Aedeagus ( Fig. 154–157 View FIGURES 142–157 ) with arc between apodemes; tectum ( Fig. 154 View FIGURES 142–157 ) slightly emarginate at proximal margin, acuminate apically from base, apical third narrow; pedon ( Figs. 155, 156 View FIGURES 142–157 ) with body strongly curved, thickened apically; apodemes slightly curved. Internal sac ( Fig. 156 View FIGURES 142–157 ) slightly longer than aedeagus, largely spiculated dorsally and ventrally at middle, ventral area smaller and denser spiculated; median sclerites strongly sclerotised ( Fig. 157 View FIGURES 142–157 ).

Female. Rostrum slightly shorter, 1.2–1.3 times as long as wide across base. Antennae short, exceeding the middle of prothorax; segments II to VIII subequal to barely decreasing in length; club thickener with segments IX and XI subequal in length and evidently longer than remaining segments (II = 0.4–0.8; III = 0.3–0.7; IV = 0.4–0.6; V = 0.3–0.5; VI = 0.3–0.5; VII = 0.3–0.5; VIII = 0.2–0.5; IX = 0.5–0.8; X = 0.3–0.5; XI = 0.6–0.8). Elytra weakly flattened, apical declivity more evident. Ventrite V expanded on each side at apex. Terminalia similar to that of P. mixtus   , differing by tergite VIII weakly constricted at apical third, sternite VIII almost rounded at apical margin, and spermathecal gland slightly longer than spermatheca.

Measurements, in mm, male/female, respectively. TL = 8.3–24.5/11.8–22.0; RL = 1.2–4.1/1.4–3.0; RAW = 1.4–2.6/1.3–2.5; RBW = 0.9–2.2/1.1–2.2; HW = 1.2–3.0/ 1.6–2.5; DSO = 0.5–2.2/0.5–1.1; MLO = 0.8–1.8/0.9–1.5; PL = 2.1–6.7/3.1–6.2; PW = 2.0–5.5/2.8–5.2; EL = 5.5–16.0/7.6–14.7; EW = 2.3–6.7/3.3–6.3.

Variability

Ventral body surface often subglabrous medially. The rugae of central pronotal depression may be inconspicuous in front of tubercle.

Type material

Not examined. According to Kuschel (1955), deposited in the University of Halle , Germany (ex­col. E. F. Germar)   . Type locality: Germar (1824) mentioned only “ Brazil ”.

Remarks

P. elongatus   is the sister group of P. nebulosus   by the synapomorphies: presence of fusiform scales at apical two thirds of the males elytra (2 1); prosternal furrow vestigial (24 3); elytra converging apically from basal third, dorsally impressed between suture and interstriae 3 (27 2), with subtransverse anteapical tubercles at beginning of apical declivity (31 4).

P. elongatus   differs from P. nebulosus   by: 1) ventral surface medially clothed with brownish pilosity; 2) groove of anterior margin of both metasternum and intercoxal process of ventrite I, vestigial. In P. nebulosus   , the pilosity of ventral surface is whitish throughout, and the anterior margin of the metasternum and ventrite I is deeply grooved.
