Prothorax orangish, except one large dark brown band on each side of pronotum. Ventral surface of meso- and metathorax orangish. Scutellum orangish. Elytra black, with slightly violaceous reflections. Femoral peduncles yellowish; pro- and mesofemoral club reddish brown except dark brown apex; metafemoral club reddish brown basally, black on remaining surface. Pro- and mesotibiae orangish; metatibiae orangish basally, black on remaining surface. Pro- and mesotarsi orangish, except brownish posterior half of tarsomere V and claws; metatarsomeres I–II dark brown, III brownish, IV and basal half of V orangish, and posterior half of V and claws brown. Abdomen black, except sides of apex of ventrite V somewhat reddish brown, and sides of apex of VI yellowish white.

Area behind upper eye lobes almost glabrous close to eye, with abundant yellowish pubescence not obscuring integument on wide central area, and sparse yellowish pubescence close to prothorax. Area behind lower eye lobes glabrous; area under lower eye lobes with somewhat long, erect, abundant yellowish setae. Genae with a few minute yellowish setae. Wide central area of postclypeus with sparse, somewhat fine, shallow punctures; with short, sparse yellowish setae. Sides of postclypeus smooth, glabrous. Labrum with long, erect, somewhat sparse yellowish setae. Gulamentum smooth, glabrous on posterior 3/4; anterior quarter finely, shallowly punctate laterally, almost smooth centrally, with a few short, erect yellowish setae. Distance between upper eye lobes 0.28 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.54 times distance between outer margins of eyes. Antennae 2.0 times elytral length, reaching elytral apex at apex of antennomere VIII. Scape pedunculate-clavate (peduncle arched); almost smooth dorsally, finely punctate laterally and ventrally; mostly glabrous dorsally, with yellowish-brown pubescence ventrally and laterally (pubescence more abundant ventrally). Pedicel with yellowish-brown pubescence not obscuring integument, partially bristly dorsally, and long, erect, thick brownish setae ventrally. Antennomeres III–IV cylindrical, with yellowish-white pubescence not obscuring integument, and long, erect, thick, sparse brownish setae ventrally. Antennomeres V–X with posterior area slightly widened, with yellowish-white pubescence not obscuring integument; V with long, erect, thick, sparse brownish setae ventrally; XI acuminate apically, with yellowish-white pubescence not obscuring integument. Antennal formula based on length of antennomere III: scape = 1.15; pedicel = 0.23; IV = 1.46; V = 1.57; VI = 1.54; VII = 1.50; VIII = 1.34; IX = 1.27; X = 1.19; XI = 1.34.

Thorax. Prothorax as long as wide; sides rounded between anterolateral angles and anterior constriction, with large, almost conical tubercles centrally, then subparallel-sided toward posterolateral angles. Pronotum tumid on each side of anterior fifth, close to lateral rounded area of prothorax; with one large gibbosity on each side, between anterior and posterior constrictions, slight more elevated anteriorly, and elongate central gibbosity between middle and posterior constriction, slightly more elevated than lateral gibbosities; lateral gibbosities surrounded internally and posteriorly with narrow L-shaped sulcus; with abundant yellowish-white pubescence not obscuring integument, except on central gibbosity, sides of anterior fifth (area of rounded anterior area of prothorax), and inner superior area of lateral gibbosities; with long, erect, sparse yellowish setae interspersed. Sides of prothorax glabrous anteriorly, with minute yellowish-white pubescence (slightly distinct) centrally, and abundant yellowish pubescence posteriorly; with a few long, erect yellowish setae interspersed posteriorly. Prosternum with yellowish-white pubescence not obscuring integument on posterior half, and a few short, erect setae of same color interspersed; anterior half not pubescent, with a few short, erect yellowish setae on anterior half. Prosternal process narrow on anterior half, strongly widened on posterior half toward truncate apex. Sides of ventral surface of mesothorax with abundant yellowish-white pubescence not obscuring integument, and central area with sparse pubescence of same color. Metanepisternum with abundant yellowish pubescence not obscuring integument, and long, erect setae of same color interspersed. Sides of metaventrite with somewhat abundant yellowish pubescence not obscuring integument, and long, erect setae of same color interspersed; central area of metaventrite glabrous, except a few long, erect yellowish setae. Scutellum almost glabrous. Elytra. Reaching about apex of abdominal segment II; parallel-sided, with inner margin strongly dehiscent from basal third; apex rounded; lateral carina strongly well-marked from anterior fifth to apex; coarsely, abundantly punctate; dorsal surface with grayish-white pubescence not obscuring integument, and a few long, erect yellowish-white setae interspersed, longer and more abundant on anterior third; sides almost glabrous. Legs. Femora with long, erect, sparse yellowish-brown setae, and sparse pubescence of same color on dorsal surface of femoral club. Protibiae nearly glabrous dorsally, with long, erect, sparse yellowish-brown setae on sides and ventral surface of basal quarter, and dense, bristly yellowish pubescence on remaining surface (sides with long, erect yellowish-brown setae interspersed on pubescent area). Mesotibiae nearly glabrous dorsally, with long, erect, yellowish-brown setae on basal 2/3, and dense yellowish pubescence on remaining surface (sides with long, erect yellowish-brown setae interspersed). Metatibiae with long, erect, sparse reddish-brown setae throughout, and bristly yellowish pubescence on ventral surface of posterior quarter. Metatarsomere I about as long as II–III together.

Abdomen. Ventrites 1–4 with dense yellowish pubescence on posterior half of sides, and long, erect, sparse yellowish-brown setae on remaining surface; 5 with a few long, erect yellowish-brown setae laterally, almost glabrous centrally; 6 nearly glabrous.

Dimensions (mm) (only one male measured). Total length, 7.25; prothoracic length, 1.20; anterior prothoracic width, 0.85; posterior prothoracic width, 1.15; maximum prothoracic width, 1.30; humeral width, 1.60; elytral length, 3.90.

Material examined. BOLIVIA, Santa Cruz: Floripondio (East), 18º08’S, 63º44’W, 1914 m, 1 male, 1 female, 29.XI.2009, R. Clarke & S. Zamalloa leg. ( MZSP); 2-3 km N Bella Vista, 4.500’, 18º11’S, 63º42’W, 30.XI.2013, Wappes & Skillman leg. ( FSCA) .

Remarks. Oxycoleus flavipes was described based on a single female from Bolivia (Santa Cruz). Clarke & Zamalloa (2018) examined males of this species, but they did not describe them. Males and females ( Figs 30–31 ) are very similar, and both have some chromatic variation: the dark transverse band on dorsal surface of head may be absent; the size of the dark maculae on the pronotum is variable, and may be small; the ventral surface of metathorax may be partially brown; and some ventrites may be yellowish brown.
