Ptychoderes longicollis Jordan, 1894: 592 ; Bovie, 1906: 219 (cat.); Wolfrum 1929: 6 (cat.); Blackwelder, 1947: 765 (cat.); Rheinheimer, 2004: 10 (cat.).

Male. Vestiture ( Fig. 211 ): pale dorsal vitta with dense, appressed whitish scales intermingled with brownish, decumbent scales denser on rostrum, pronotum and elytral interstriae 1–2 and 4. Sides of pronotum, epipleura, elytral apical declivity and pygidium with predominance of brown scales. Ventral body surface and legs with dense, appressed, yellowish­white scales. Sides of prosternum, below lateral carina, with a continuous dark vitta of blackish­brown scales, narrowed between pleural suture and posterior margin of prothorax. Sides of mesosternum with a narrow glabrous vitta. Anterior angles of ventrites clothed with dense, appressed blackish­brown scales. Mesepimera, episterna and sides of metasternum with dense, coarse setigerous punctures, each provided with a brownish scale; these punctures shallower and sparser at sides of ventrites. Outer surface of meso­ and metafemora with two spots of blackish­brown scales.

Rostrum 1.3–1.4 times as long as wide across base. Distance between scrobe and eyes about half the eye’s maximum width. Sides feebly swollen and bicarinate; carinae oblique, joining at dorsal margin of scrobe; with a large, dull area coarsely, contiguously punctate below carinae. Scrobes careniform at dorsal margin; extension shallow, wide with two deep pits, one proximal to scrobe, and one distal, deeper and wider than extension. Mentum finely, densely punctate; strongly impressed at sides and shallowly grooved at apical margin. Gula with dense, coalescent, moderately coarse punctures. Frons with prominent carinae.

Antennae elongate ( Fig. 211 ), exceeding elytral apices by two club segments. Segment II half as long as III; III to VII increasing in length; VIII one third longer than IX; this 3 times as long as X; XI short, half as long as IX (II=1.1–1.2; III=2.2–2.2; IV=2.6–2.5; V=2.7–2.7; VI=2.9–2.9; VII=3.2–3.2; VIII=2.9–2.8; IX=2.2–2.1; X=0.7–0.6; XI=1.0–1.0).

Prothorax ( Figs. 211 , 243 ) elongate, at least 1.2 times as long as wide; sides subparallel, weakly narrowed near apical margin. Pronotal depression shallow, deeper near antebasal carina, with a prominent, more or less transverse, median tubercle reaching lateral margins of depression ( Fig. 243 ). Pronotum transversely rugose throughout, rugae prominent. Antebasal carina interrupted at middle (about twice width of carina), sinuous and oblique towards lateral carina. Lateral carina strongly sinuous and prominent. Secondary carina straight, widely interrupted at middle, not reaching lateral carina. Laterobasal carina not reaching posterior margin of prothorax. Prosternum almost flat ( Fig. 257 ), with moderately coarse, deep punctures, irregularly dense; antecoxal furrow narrow, shallow and sinuous with a small prosternal projection at middle not interrupting the furrow. Mesosternum with moderately coarse, shallow, irregularly sparse punctures, and a deep, irregularly transverse impression near the intercoxal process. Intercoxal process of mesosternum impressed at apex, swollen at lateral and apical margins, without lateroapical projections. Elytra 2.2 times as long as wide across humeri, weakly depressed at basal two thirds, convex at apical third; basal gibbosities weakly prominent; surface rugose from base to behind middle, more so at base and near suture. Sides subparallel, convergent at apical third. Anteapical tubercles poorly conspicuous, interstriae 3–9 barely swollen, 3 and 9 more raised. Wings without radial cell.

Abdomen. Intercoxal process of ventrite I deeply grooved, sex patch absent. Ventrite V not impressed on disk; apex slightly emarginate. Pygidium ( Fig. 53 ) slightly wider than long, depressed, with an elongate groove to fit elytra; apex truncate.

Terminalia. Tergite VIII ( Fig. 79 ) slightly wider than long, convergent apically, apex largely rounded; sternite VIII ( Fig. 93 ) strongly transverse, subparallel­sided, deeply emarginated at apex forming large lateral lobes; apodeme narrow, longer than wide and sclerotized; apodeme of sternite IX ( Fig. 107 ) twice as long as arms. Tegmen ( Fig. 121 ) obliquely truncate at apex. Aedeagus ( Fig. 162–164 ) with arc between apodemes; tectum ( Fig. 163 ) slightly curved at proximal margin, acuminate apically from middle; pedon ( Fig. 162, 164 ) with body thick, slightly curved, rounded at apex; apodemes strongly curved near body of pedon. Internal sac ( Fig. 162 ) slightly shorter than aedeagus, spiculated dorsally at distal half, lacking sclerites.

Female. Rostrum slightly shorter, 1.2 times as long as wide across base; sides not swollen. Antennae shorter, exceeding the posterior margin of prothorax by one segment; segments II to VII subequal in length; VIII slightly shorter than VII; IX and XI subequal; X shortest (II = 0.6–0.7; III = 0.7–0.7; IV = 0.8–0.9; V = 0.7–0.8; VI = 0.6–0.7; VII = 0.7–0.8; VIII = 0.5–0.6; IX = 0.7–0.8; X = 0.4–0.5; XI = 0.7–0.7). Ventrite V more strongly emarginate at apex. Terminalia: tergite and sternite VIII similar to those of P. mixtus , differing by the rounded apex; ovipositor with three moderately developed teeth, successively smaller; median rods slender, acuminate at proximal margin; median ventral lobe bilobated; bursa copulatrix lacking ventral lobe; spermathecal gland slightly longer than spermatheca.

Type material

Male holotype ( BMNH) examined, labelled as follows: 1) Type [rounded, white with red border, printed]; 2) Suriname [square, white, handwritten]; 3) Ptychoderes longicollis , male, Type!, Jordan [square, white, handwritten]. Type locality: Suriname.

Remarks. The relationship of P. longicollis with the clade P. jordani + is supported by synapomorphies referent to the shape of male tergite VIII (39 2), and the ovipositor with three moderately developed teeth and slender median rods which are acuminate at the proximal margin (characters 47 2 and 48 1). P. longicollis is also similar to the species of the group P. obsoletus + by vestiture and pronotum transversely rugose throughout, differing by the elongate, parallel­sided prothorax and shallow, narrow, sinuous prosternal furrow. This type of furrow, presence of black spots at the anterior angles of ventrites, and the strongly sinuous lateral carina of prothorax also occur in the P. bivittatus + group.
