(Figs 16–18)
Coloration. Integument reddish-brown, darker on some areas; head mostly brown dorsally; scape dark-brown; pedicel dark-brown on basal 2/3, reddish on distal third; antennomeres dark-reddish brown, gradually lighter toward distal antennomeres; antennomeres III–IV with longitudinal, dorsal, narrow dark-brown band; elytra with subtriangular, yellow macula on basal half, blackish on about distal fifth; femoral peduncle mostly dark-brown; femoral club blackish; tibiae brown on base, gradually lighter toward apex.
Head. Frons slightly tumid on large, transverse area close to clypeus; tumid area finely, abundantly striate, except for smooth, longitudinal area; with moderately deep fovea at each side of tumid area; finely, abundantly punctate on triangular area above tumid area; glabrous on tumid area, with short, decumbent, sparse setae on punctate area. Area between antennal tubercles finely, confluently punctate. Area between antennal tubercles and posterior margin of eye microsculptured, moderately coarsely, sparsely punctate, almost glabrous. Area between upper eye lobes and prothoracic margin slightly tumid centrally, finely, sparsely punctate, almost glabrous centrally, with short, sparse setae close to eyes. Area behind upper eye lobes finely, sparsely punctate; with short, sparse setae; with one long seta near eye. Area behind lower eye lobes smooth, glabrous on region closer to upper eye lobe, finely rugose-punctate toward ventral side on region closer to eye, finely, sparsely punctate toward prothoracic margin; with long, erect, sparse setae on rugose-punctate area, glabrous on remaining surface. Area between lower eye lobes and submentum finely rugose-punctate, with short, sparse setae interspersed with long setae. Antennal tubercles slightly elevated, with apex rounded; finely, sparsely punctate. Longitudinal sulcus distinct only on area between antennal tubercles and posterior margin of eyes. Submentum transversely striate; with short, sparse setae interspersed with long, erect seta. Genae finely, moderately abundantly punctate close to eye, smooth toward apex; with short, sparse setae close to eye, glabrous toward apex. Distance between upper eye lobes 0.4 times length of scape; distance between lower eye lobes in frontal view 0.7 times length of scape. Antennae 3.0 times elytral length, reaching elytral apex near apex of antennomere VI; scape with distinct dorsal furrow; antennomeres III–IV with long, erect setae at inner side; antennal formula (ratio) based on antennomere III: scape = 0.58; pedicel = 0.16; IV = 1.02; V = 1.10; VI = 1.07; VII = 0.98; VIII = 0.94; IX = 0.98; X = 0.98; XI = 1.33.
Thorax. Prothorax 1.4 times longer than wide; laterally slightly rounded. Pronotal disc with five tubercles: two slightly indicated anterolaterally; two small, conical posterolaterally; one more distinct, moderately elongate, placed near middle. Pronotal surface finely, sparsely punctate; with transverse depression between posterolateral tubercles; with very short and sparse, decumbent setae (slightly denser basally), interspersed with long, erect, sparse setae. Sides of prothorax microsculptured on transverse basal band, smooth, almost glabrous on remaining surface (slightly microsculptured near anterior margin). Prosternum smooth on basal half; transversely striate on distal half; with narrow band of white pubescence close to procoxal cavities, fused with narrow, longitudinal, lateral band on basal half; remaining surface with short, very sparse setae. Mesothorax tumid toward mesosternal process; pubescent laterally, with short, sparse setae centrally. Mesepisterna and mesepimera pubescent. Mesosternal process with short, moderately abundant setae (mainly laterally) interspersed with long, erect setae. Metepisterna pubescent. Metasternum coarsely, sparsely punctate near middle; with short, decumbent, abundant setae laterally, distinctly sparser toward center; with long, sparse, erect setae between area with abundant short setae and center. Scutellum pubescent, more distinctly at apex.
Elytra. Coarsely, moderately abundantly punctate on basal half, gradually finer, sparser toward apex; with long, erect setae aligned in 4 rows (setae longer on basal third, not distinctly aligned on distal third); apex with spine at outer angle, projected at sutural angle.
Legs. Femora distinctly clavate (mainly meso- and metafemora); with long, sparse, erect setae. Tibiae carinate laterally. Metatarsomere I slightly shorter than II–III together.
Abdomen. Ventrites with short, decumbent, sparse setae interspersed with long, erect setae; apex of ventrite V slightly emarginate centrally.
Dimensions (mm). Total length (including mandibles), 7.90; prothoracic length, 1.80; anterior prothoracic width, 1.20; basal prothoracic width, 1.25; largest prothoracic width, 1.30; humeral width, 1.70; elytral length, 5.10.
Type material. Holotype male from BOLIVIA, Santa Cruz: Florida (4 km N Bermejo; Refugio los Volcanes; 18º06’S / 63º32’W; 1000–1200 m), 25.X.2011, Skillman & Wappes col. (MNKM).
Etymology. This new species is named after our friend James E. Wappes.
Remarks. Tropidion wappesi sp. nov. is similar to T. acanthonotum (Martins, 1962), T. brunniceps (Thomson, 1865), T. kjellanderi (Martins, 1965), and T. salamis (Thomson, 1867) by the general elytral color, but differs mainly by the presence of yellow macula on the basal half of the elytra (absent in these species), and by the metafemoral club which is distinctly wider.
Tropidion wappesi can be included in the alternative of couplet “16”, from Martins & Galileo (2007) (translated; modified):
16’(15) Largest width of metafemoral club about 4.0 times width of peduncle. Bolivia ................. Tropidion wappesi sp. nov. - Largest width of metafemoral club about 2.5 times width of peduncle.......................................... 16 16(16’) Small dimensions and slender general appearance (length, 5.7–8.1 mm; humeral width, 1.1–1.6 mm); anterior half of elytra
convex. Brazil (Bahia to Santa Catarina, Goiás)........................................ T. sipolisi (Gounelle, 1909) - Largest dimensions and robust general appearance (length, 7.0– 11.1 mm; humeral width, 1.5–2.8 mm); anterior half of elytra
