Description: Holotype male: Integument mostly black; frons, anterior portion of vertex, about middle of genae, basal portion of area behind lower eye lobes, and mouthparts orangish brown, except brown distal segments of palpomeres; postclypeus reddish brown laterally; anteclypeus orangish yellow; anterior ⅔ of labrum brown, remaining surface orangish yellow; prothorax orangish brown on anterior and posterior quarter; longitudinal area on middle of mesoventrite, and mesoventral process orangish brown; scape, pedicel and antennomeres III-IV orangish basally, black in remaining area; antennomeres V-XI light orangish brown on basal half, dark brown on posterior half; vitreous orangish-yellow area of elytra starting at base, somewhat orangish-brown close to scutellum, becoming slightly translucent posteriorly, gradually narrower toward apex, not reaching apex; pro- and mesocoxae orangish brown; metacoxae, trochanters and anterior ⅔ of femora orangish yellow, posterior third of femora dark brown;tibiae and tarsi dark brown,except orangish-brown anterior third of tarsomere II, somewhat darker on basal portion of tarsomere I.

Head: Frons moderately coarsely, abundantly punctate, with yellowish-white pubescence. Median groove distinct from postclypeus to vertex, especially between eyes. Vertex and area behind upper eye lobes coarsely, abundantly punctate; both short and long yellowish setae, sparser behind upper eye lobes. Antennal tubercles elevated, somewhat coarsely, shallowly, sparsely punctate; with short, erect, scattered yellowish setae. Area behind lower eye lobes shallowly rugose-punctate; with short, sparse yellowish setae, interspersed with long, erect yellowish setae close to eye. Genae about half length of lower eye lobe; moderately finely, sparsely punctate except smooth apex; with short, sparse yellowish setae except glabrous smooth area, with long, erect setae of same color interspersed toward ventral surface. Wide central area of postclypeus with sculpturing as on frons, except smooth sides; with yellowish-white pubescence partially obscuring integument centrally, glabrous laterally; with one long, erect, yellowish seta on each side. Gulamentum smooth, glabrous on posterocentral area; moderately coarsely, sparsely striate-punctate on middle, obliquely striate, with finer punctures on anterocentral area; with long, erect yellowish seta emerging from each puncture on sides of anterior area, almost absent centrally. Distance between upper eye lobes 0.62 times length of scape; in frontal view, distance between lower eye lobes 0.20 times length of scape. Antennae 1.2 times elytral length, reaching posterior quarter of elytra. Scape coarsely, abundantly punctate, punctures sparser ventrally; with long, erect, sparse yellowish setae, dens- er ventrally. Pedicel and antennomeres III-IV with short, erect yellowish setae; antennomeres V-XI with brownish pubescence,and short,scattered yellowish setae;pedicel and antennomere III-VII with long, erect brownish setae on ventral surface; antennomeres III-V nearly cylindrical, very slightly widened toward apex; antennomeres VI-XI gradually widened toward apex. Antennal formula (ratio) based on length of antennomere III: scape = 0.75; pedicel = 0.25; IV = 0.57; V = 0.89; VI = 0.78; VII = 0.71; VIII = 0.64; IX = 0.57; X = 0.50; XI = 0.66.

Thorax: Prothorax 1.17 times longer than wide;posterior constriction well-marked; sides slightly rounded, anteriorly; posterior margin sinuous. Pronotum coarsely, abundantly punctate; with abundant yellowish pubescence; with long, erect, sparse yellowish setae throughout. Sides of prothorax with sculpturing as on pronotum, with yellowish-white pubescence, denser than pronotum. Prosternum coarsely, abundantly punctate on posterior ⅔; with transverse band of punctures on central area of anterior third, followed by narrow, smooth band; with abundant, long, erect yellowish setae. Narrowest area of prosternal process 0.25 times width of procoxal cavity; posterior area triangular. Mesoventrite finely, densely punctate, somewhat striate; with abundant yellowish pubescence, slightly denser laterally. Mesanepisternum and mesepimeron with dense, thick yellowish pubescence. Metaventrite and metanepisternum with dense yellowish-white pubescence, denser and thicker on anterior half of metaventrite and laterally on metanepisternum; with long, erect, sparse yellowish setae, denser laterally on metaventrite. Scutellum with short, scattered yellowish setae, apex emarginate. Elytra: Coarsely,abundantly punctate, punctures slightly finer toward apex, sparser on vitreous area; sides longitudinally concave from near base to near apex; sutural margins slightly divergent from posterior half; with very short, erect yellowish setae, gradually sparser toward apex; with long, erect, sparse yellowish setae on anterocentral area, close to scutellum; vitreous area with short, sparse yellowish setae; apex obliquely truncate, with short, erect yellowish setae. Legs: Coxae and trochanters with long, erect yellowish-orange setae. Femora with long, erect, sparse yellowish setae. Protibiae with short, erect yellowish-brown setae, distinctly denser ventrally, and long, erect setae on outer margin; meso- and metatibiae with long, erect, sparse yellowish setae, slightly denser laterally and ventrally. Tarsi with long, erect brownish setae. Metatarsomere I as long as II-III together.

Abdomen: Subcylindrical. Ventrites 1-3 very sparsely, finely punctate except smooth distal area; with long, erect, sparse yellowish setae except on smooth distal area. Ventrite 4 with punctures and erect setae distinctly more abundant than on 1-3, slightly denser laterally, except on smooth and glabrous distal area. Central area of ventrite 5 gradually depressed from near base to apex; with moderately abundant, long, erect yellowish setae throughout; apex concave with central area rounded and projected.

Dimensions (mm): holotype male/ paratype male: Total length 12.25/11.65; prothoracic length 2.55/2.25; anterior prothoracic width 1.70/1.40; posterior prothoracic width 1.65/1.35; maximum prothoracic width 1.90/1.60; humeral width 3.00/2.65; elytral length 6.15/5.85.

Type material: Holotype male labeled: “ GUATEMALA: El Petén, Sayaxche. Parque Nac. El Rosario. 150 msnm. 17/ junio/1999, E. Cano ”. ( UVGC) . Paratype male: same data, except: 19/junio/1999. ( UVGC).

Etymology: The specific name nigroaurantia is composed from the Latin “niger, nigro” (black) and “aurantia” (orange), referring to the combination of black and orange integument.

Remarks: Odontocera nigroaurantia sp. nov. ( Fig. 3 ) is similar to O. annulicornis Magno, 2001 , and O. molorchoides (White, 1855) (see photographs on Bezark, 2022b). It differs from both by the femora in the male holotype specimen, especially the metafemora, shorter and club distinctly stouter (longer and club slender in O. annulicornis and O. molorchoides ).
