Ptychoderes jordani Frieser, 1959: 416 ; 1979: 109; Rheinheimer, 2004: 10 (cat.).

Male. Vestiture ( Figs. 212–214 View FIGURES 208–214 ): pale dorsal vitta with dense, decumbent, appressed whitish scales intermingled with green (greenish­ochreous in pale forms, Fig. 214 View FIGURES 208–214 ), decumbent scales denser on head, pronotum and elytra. Pygidium with predominance of green scales, brown scales scarce. Ventral body surface and legs with dense, appressed yellowish­white scales. Prosternum subglabrous; at sides, below lateral carina, with a dark vitta of blackish­brown scales narrowed posteriorly towards lateral carina, and narrowly divided by yellowish­white scales running along pleural suture. Sides of mesosternum with a narrow glabrous vitta. Mesepimera, episterna and sides of metasternum with dense, setigerous punctures deeper in mesepisterna, each provided with a brownish scale; these punctures shallow and sparse at sides of ventrites. Outer surface of meso­ and metafemora with a strip of blackish­brown scales.

Rostrum 1.1–1.5 times as long as wide across base. Distance between scrobe and eyes about half maximum width of eye. Sides looking tricarinate because of careniform upper margin of scrobe; carinae suboblique, upper one slightly thicker than lower carina. Scrobes careniform at dorsal and basal margins; extension wide, shallow with two deep, subequal pits, one proximal to scrobe, and one distal. Mentum finely, sparsely punctate, strongly impressed at sides and shallowly grooved at apical margin. Gula with shallow, sparse, moderately coarse punctures. Frons with prominent carinae.

Antennae ( Fig. 212 View FIGURES 208–214 ) from short, reaching elytral basal third to moderately long, slightly exceeding the middle of elytra. Segment II one third shorter than III; IV longest, slightly longer than V; V to VIII subequal in length; IX slightly shorter than VIII, twice as long as X; this slightly longer than wide and half as long as XI (II = 0.4–1.0; III = 0.6–1.6; IV = 0.7–1.9; V = 0.6–1.8; VI = 0.5–1.8; VII = 0.6–1.8; VIII = 0.5–1.7; IX = 0.6–1.3; X = 0.4–0.7; XI = 0.6–1.4).

Prothorax ( Figs. 212–214 View FIGURES 208–214 , 244 View FIGURES 239–250 ) slightly wider than long, sides almost rounded feebly converging anteriorly from antebasal carina, anterior margin conspicuously narrowed. Pronotal depression deep, divided by a prominent, more or less transverse tubercle reaching lateral margins of depression. Pronotum transversely rugose throughout, rugae more prominent and long at the anteromedian region and on tubercle. Antebasal carina interrupted at middle (subequal to twice width of carina), oblique towards lateral carina. Lateral carina strongly sinuous. Secondary carina more or less straight, widely interrupted at middle, almost reaching lateral carina. Laterobasal carina reaching posterior margin of prothorax. Prosternum raised, with coarse, deep, dense punctures; antecoxal furrow deep, slightly wide, slightly sinuous and entire. Mesosternum with moderately coarse, shallow, irregularly sparse punctures, and deep, irregularly transverse impression near the intercoxal process. Intercoxal process of mesosternum longitudinally impressed, swollen at lateral and apical margins, without lateroapical projections. Elytra about twice as long as wide across humeri, weakly depressed at basal two thirds, the apical third convex; basal gibbosities somewhat prominent; surface rugose from base to behind middle, more so at base and near suture. Sides subparallel, slightly attenuate apically from behind middle. Anteapical tubercles absent, interstriae 3–9 barely swollen. Radial cell of wing present or absent.

Abdomen. Ventrite I with very small, almost rounded setiferous sex patch, clothed with dense, erect, moderately long, yellowish pubescence; intercoxal process deeply grooved. Ventrite V not impressed, slightly emarginate at apex. Pygidium as wide as long, depressed, with an elongate groove to fit elytra; sides convergent, apical margin roundedtruncate.

Terminalia. Tergite VIII ( Fig. 80 View FIGURES 70–84 ) slightly wider than long, convergent at sides, rounded at apex; sternite VIII ( Fig. 94 View FIGURES 85–112 ) with sides convergent, the apical margin bilobate, apodeme triangular and sclerotized; apodeme of sternite XI ( Fig. 108 View FIGURES 85–112 ) twice as long as arms. Tegmen ( Fig. 122 View FIGURES 113–126 ) rounded at apex. Aedeagus ( Figs. 165–168 View FIGURES 158–176 ) without arc between apodemes; tectum ( Fig. 166 View FIGURES 158–176 ) curved at proximal margin, acuminated at apex; pedon ( Figs. 165, 167 View FIGURES 158–176 ) with body weakly curved, narrowed apically; apodemes curved. Internal sac (fig. 165) slightly shorter than aedeagus, spiculated medially; antemedian sclerites narrow and weakly sclerotized ( Fig. 168 View FIGURES 158–176 ).

Female ( Fig. 213 View FIGURES 208–214 ). Rostrum slightly shorter, 1.1–1.2 times as long as wide across base; extension of scrobe deep. Antennae shorter, exceeding antebasal carina of prothorax; segments II–III subequal in length; IV slightly longer than V; V–VII subequal in length; VIII barely shorter than IX; this slightly longer than X and subequal to XI (II = 0.4–0.8; III = 0.5–0.8; IV = 0.5–1.0; V = 0.5–0.8; VI = 0.5–0.7; VII = 0.4–0.8; VIII = 0.3–0.7; IX = 0.6–1.0; X = 0.4–0.7; XI = 0.6–1.0). Elytra more convex. Pygidium slightly longer than wide. Ventrite V with apical margin truncate. Terminalia: tergite VIII ( Fig. 189 View FIGURES 177–195 ) almost twice as long as wide, subparallel at sides, truncate at apex; sternite VIII ( Fig. 190 View FIGURES 177–195 ) almost as long as apodeme, sinuous at apex; ovipositor ( Figs. 191–192 View FIGURES 177–195 ) similar to that of P. longicollis , differing by the median ventral lobe acuminate at apex.

Measurements, in mm, male/female. TL = 11.8–18.7/11.7–20.8; RL = 1.6–2.5/ 1.6–2.7; RAW = 1.6–2.2/1.6–2.7; RBW = 1.4–1.6/1.5–2.2; HW = 2.0–2.8/1.8–3.1; DSO = 0.5–0.9/0.3–1.0; MLO = 1.1–1.7/1.1–1.6; PL = 3.2–4.8/3.2–5.3; PW = 3.3–5.0/3.3–5.7; E L = 7.7–12.0/7.3–13.7; EW = 3.7–5.5/3.4–6.5.


Either the light brown or the green scales may be denser at the sides of both pronotum and elytra, even in pale forms ( Figs. 212–214 View FIGURES 208–214 ).

Type material Male holotype ( BMNH) examined, with following labels: 1) TYPE [rounded, white with red border]; 2) HOLOTYPE [red]; 3) Cay., 58.74 [white]; 4) Ptychoderes jordani m. sp. n. det. R. Frieser 1955 [white]; 5) male, Cayen. BAR [white]. Female paratype ( ZSMA) examined, labelled as follows: 1) Bolivia , Chaparé, Villa Tunari, 400 m, III.53 [white]; 2) Ptychoderes jordani sp. n., Paratype, female, det. R. Frieser, 1959 [white]; 3) Zool. Staatsseg München [blue]. Type locality: Cayenne , French Guiana .

In addition to the holotype ( Fig. 212 View FIGURES 208–214 ) and paratype ( Fig. 213 View FIGURES 208–214 ), three specimens identified by Karl Jordan in 1950 (ISNB) were examined, one of them labelled as a paratype of P. subviridis (name in litt.). Two of these specimens actually belong to P. jordani and one to P. jekeli Mermudes and Napp, 2004 . According to Frieser (1959), P. jordani was based on the material previously identified by Karl Jordan as P. viridanus Boheman, 1833 . However, the holotype and the paratype of P. jordani do not have Jordan’s identification labels, and because of the similarity of the names “ subviridis ” ( Jordan, in litt.) and P. viridanus , it is possible that the type material of P. jordani was actually studied by Jordan.


The following synapomorphies support P. jordani as sister group of the group P. obsoletus +: pygidium elongate and impressed (32 1); aedeagus without arc between apodemes (41 0); internal sac with antemedian sclerites (45 1); tergite VIII of females longer than wide, with dense, long hairs at sides (46 1); and ventral median lobe of ovipositor acuminate at apex (49 1).

By the green dorsal vestiture, P. jordani looks like P. viridanus and P. jekeli ( Figs. 223 View FIGURES 221–227 , 210 View FIGURES 208–214 ). The pronotal depression and the transverse tubercle are similar in P. jordani and P. viridanus , but the pronotum is evidently rugose throughout, with elongate rugae in the former, while in P. viridanus the pronotum is not rugose (if present, then rugae restricted inside the depression). P. jekeli is similar to P. jordani regarding the rugose pronotum, differing by the slightly deep pronotal depression with an almost rounded tubercle that does not reach the lateral margins of depression.
