Ptychoderes rugicollis Jordan, 1895: 122 ; Bovie, 1906: 220 (cat.); Jordan, 1906: 303, t. 10, Figs. 2, 2a ; Wolfrum, 1929: 6 (cat.); Blackwelder, 1947: 765 (cat.); Howden, 1992: 20 (biology, morphology); Rheinheimer, 2004: 10 (cat.).

Male. Vestiture ( Fig. 222 ): pale dorsal vitta with dense whitish to yellowish­white scales, intermingled with scarce, decumbent, brownish to pale scales, denser on elytral interstriae 2 and 4; sides of pronotum, epipleura, elytral declivity and pygidium with predominance of brown scales. Ventral body surface and legs with appressed, dense yellowish­white scales. Sides of prosternum, below lateral carina, with continuous dark vitta of blackishbrown scales, slightly narrowed between pleural suture and posterior margin of prothorax. Sides of mesosternum with wide glabrous vitta. Anterior angles of ventrites with dark spots of blackish­brown scales. Mesepisterna with coarse setigerous punctures, each provided with a brownish scale; these punctures deeper at sides of ventrite I, and shallow at sides of ventrites II–V. Outer surface of meso­ and metafemora with two spots of blackish­brown scales. Apical half of tarsomera I, II and IV with spot of blackish­brown scales. Rostrum 1.3–1.7 times as long as wide across base. Distance between scrobe and eyes subequal or slightly longer than maximum width of eye. Sides bicarinate; carinae oblique and thickener near scrobe; strongly impressed between carinae near ocular margin; with coarse, coalescent punctures close to scrobal margin. Scrobes careniform at dorsal and basal margins; extension shallow, wide with thick, not careniform margin, and deep distal pit slightly wider than extension. Mentum moderately coarse, sparsely punctate, grooved at sides, apical margin shallowly grooved. Gula with sparse, fine punctures. Frons with

weakly prominent carinae.

Antennae ( Fig. 222 ) from short, reaching elytral basal third, to longer than body, exceeding elytral apex by two club segments. Segments II–VII increasing in length; VIII slightly shorter than VII; IX 3 times as long as X; XI 1.5 times as long as X (II = 0.5–1.3; III = 0.6–2.4; IV = 0.8–3.0; V = 0.6–3.3; VI = 0.6–3.4; VII = 0.6–3.6; VIII = 0.5–3.3; IX = 0.7–3.2; X = 0.4–1.0; XI = 0.8–1.7).

Prothorax ( Figs. 249 , 259 ) as long as or longer than wide; sides converging anteriorly from antebasal carina. Pronotal depression deep, divided by prominent, more or less transverse tubercle reaching lateral margins of depression. Pronotum transversely rugose throughout; rugae more prominent and long on depression margins, median tubercle, and near lateral carinae, less so or missing inside depression. Antebasal carina widely interrupted at middle (at least twice width of carina), oblique towards lateral carina. Lateral carina strongly sinuous. Secondary carina suboblique towards posterior margin of prothorax, moderately interrupted at middle and almost reaching lateral carina. Laterobasal carina reaching posterior margin of prothorax. Prosternum ( Fig. 259 ) weakly raised, almost flat, with coarse, moderately deep, sparse punctures more or less obliterate by vestiture; antecoxal furrow shallow, narrow and curved, with tiny prosternal projection at middle. Mesosternum with moderately coarse, shallow, irregularly sparse punctures, and deep, irregular impressions, subcontiguous at middle near intercoxal process. Intercoxal process of mesosternum strongly impressed at base, weakly so at apex, not swollen at lateral and apical margins, without lateroapical projections. Elytra 2.0–2.3 times as long as wide across humeri, weakly impressed at basal two thirds, convex at apical third; basal gibbosities somewhat prominent; surface rugose from base to beyond middle, more evidently at basal third. Sides slightly converging apically from basal third. Anteapical tubercles prominent, rounded, interstriae 3, 5, 7 and 9 swollen. Wings with radial cell.

Abdomen. Ventrite I ( Fig. 237 ) with suboval, moderately developed setiferous sex patch closer to intercoxal process, and clothed with dense, erect, yellowish­white pubescence; intercoxal process deeply grooved. Ventrite V not impressed on disk, slightly emarginate at apex. Pygidium wider than long, subconvex at anterior half, with short groove to fit elytra, apical margin rounded­truncate.

Terminalia. Tergite VIII ( Fig. 74 ) as wide as long, subparallel at sides, apical margin rounded; sternite VIII ( Fig. 88 ) with sides convergent, apical margin emarginate with large lobes, apodeme triangular and sclerotised; apodeme of sternite IX ( Fig. 102 ) 2.8 time as long as arms. Tegmen ( Fig. 116 ) rounded at apex. Aedeagus ( Figs. 142–145 ) with arc between apodemes; tectum ( Fig. 143 ) curved at proximal margin, acuminated at apical third; pedon ( Figs. 142, 144 ) with body curved and thickened, rounded at apex; apodemes curve, oblique at proximal third. Internal sac ( Fig. 142 ) almost as long as aedeagus, spiculated medially, with median sclerites strongly sclerotized ( Fig. 145 ); lateral membrane with pigmented rods.

Female. Rostrum slightly shorter, at least 1.3 times as long as wide across base; extension of scrobe deep. Antennae shorter, exceeding middle of prothorax; segments II–VII subequal in length; VIII slightly shorter; IX twice as long as VIII; XI almost twice as long as X (II = 0.4–0.8; III = 0.3–0.7; IV = 0.4–0.9; V = 0.3–0.7; VI = 0.3–0.6; VII = 0.2–0.6; VIII = 0.2–0.4; IX = 0.4–0.8; X = 0.3–0.6; XI = 0.5–1.1). Prothorax slightly wider than long. Elytra more convex. Ventrite V weakly emarginate at apex. Terminalia similar to that of P. mixtus , differing by the 8 th tergite slightly longer than wide, slightly sinuous at sides, weakly emarginate at apex. Gland of spermatheca not observed.

Type material

Jordan (1895) based his description on six males and five females from Chiriqui ( Panama) and Chontales ( Nicaragua) . Syntypes (BMNH) not examined.

Remarks

P. rugicollis may be recognized mainly by the whitish dorsal vitta strongly contrasting with the vestiture of the sides, and the setiferous sex patch of the male ventrite I closer to the intercoxal process. See other remarks under P. callosus .
