Antennae 2.0 times ely- tral length, reaching elytral apex at middle of antennomere VII. Scape, pedicel and antennomeres III–X with long, erect, sparse yellowish setae on inner side of ventral surface, most of them brownish basally (gradually shorter, sparser toward X); scape with yellowish-brown pubescence dorsally, yellowish-white pubescence interspersed, and sparser yellowish-white pubescence toward ventral surface; antennomeres III–V with two yellowish-white pubescent bands, not reaching ventral surface, one narrow basally, another centrally (this last one gradually shorter toward V); antennomeres VI–XI with wide yellowish-white pubescent ring; remaining surface of antennomeres with dark pubescence. Antennal formula (ratio) based on length of antennomere III: scape = 0.48; pedicel = 0.14; IV = 0.75; V = 0.55; VI = 0.53; VII = 0.53; VIII = 0.50; IX = 0.49; X = 0.43; XI = 0.39.

Thorax. Lateral tubercles large, with blunt apex. Pronotum with five tubercles: one large, elevated, with round- ed apex on each side of anterocentral half; one less elevated than the former placed on each side of posterior half, rounded on apex; another elongated, slightly elevated, placed central on posterior half. Pronotal surface coarsely, somewhat sparsely punctate anteriorly and posteriorly, and finer, sparser punctate among tubercles, except on smooth tubercles; pubescence mostly yellowish-white (whiter depending on light intensity), not obscuring integument, with areas with yellowish-brown pubescence interspersed, except glabrous top of anterolateral tubercles and posterocentral tubercle; with a few long, erect, dark setae on posterior half. Sides of prothorax coarsely punctate posteriorly, with finer, sparser punctures anteriorly, and nearly smooth centrally; with light yellowish-brown pubescence not obscuring integument, distinctly pale yellow posteriorly close to procoxal cavity. Prosternum and central area of prosternal process with light yellowish-brown pubescence not obscuring integument; sides of prosternal process with yellowish-white pubescence; narrowest area of prosternal process 0.6 times width of procoxal cavity. Apex of mesoventral process 1.45 times width of mesocoxal cavity. Mesoventrite with sparse yellowish-white pubescence on wide central area, distinctly denser laterally. Mesanepisternum and mesepimeron with dense yellowish-white pubescence, with pale yellow pubescence interspersed. Metanepisternum with light yellowish-brown pubescence, gradually darker, denser toward apex. Metaventrite with yellowish-white pubescence not obscuring integument close to metanepisternum and on wide central area, pale yellow close to mesocoxal cavities, distinctly denser pale yellow laterally close to metacoxal cavities (this pubescence gradually whiter toward inner side). Scutellum semicircular, with yellowish-white pubescence not obscuring integument. Elytra. Humeri laterally projected; surface coarsely, abundantly punctate (finer, sparser after middle); apex slightly obliquely truncate, slightly concave between outer and sutural angles; with slightly arched, elevated transverse crest on basal sixth, dorsally slightly sinuous; anterior area, between base and crest, with grayish-white pubescence, denser toward crest, with tufts of yellow pubescence close to crest; with tuft of short black pubescence on outer side of crest; posterior area of crest narrowly, almost glabrous; area between crest and just before middle mostly with yellowish-brown pubescence, gradually more yellowish-white centrally toward posterior of this region, darker on inclined area, except black pubescent macula on anterior inclined third; with dense, irregular white pubescent macula about middle, not reaching suture, reaching epipleural margin (sparser close to epipleural margin); with V-shaped, narrow white pubescent band laterally after large white pubescent macula (both internally connected); posterior quarter with mostly white pubescence partially obscuring integument; area between white pubescent macula and posterior quarter mostly with yellowish-brown pubescence, except white pubescence close to suture, and three longitudinal dark brown pubescent bands, central one longest. Legs. Dorsal and lateral surfaces of femora with dense yellowish-white pubescence (whiter depending on light intensity), with yellowish-brown pubescent areas interspersed; ventral surface with pubescence of same color, shorter, sparser, especially on profemora. Tibiae with two yellowish-white pubescent rings, with yellowish pubescence interspersed, one basally, another centrally, this last one distinctly wider on metatibiae; remaining surface with dark pubescence, bristly dark brown on ventral third of protibiae, bristly reddish brown on ventral half of meso- and metatibiae. Protarsomere I two times length of II.

Abdomen. Ventrites with grayish-white pubescence not obscuring integument, with long, erect, sparse setae of same color interspersed laterally. Apex of ventrite V truncate.

Dimensions of the holotype female ( Martins & Galileo 2005): Total length, 11.20; prothoracic length, 1.80; maximum prothoracic width (between apex of tubercles), 3.20; humeral width, 4.80; elytral length, 8.50.

Material examined. COLOMBIA, Huila (New department record): Palestina , 1º40’25” N / 76º13’29”W, 2,200 m, 1 male, 16-18.IV.2018, V. Sinyaev col. ( MZSP) GoogleMaps .

Remarks. Oreodera advena was described based on a single female from Colombia (Boyacá). Monné & Hovore (2006) recorded the species from Ecuador. The male of O. advena differs from the female by the longer antennae, reaching elytral apex at middle of antennomere VII (apex of VIII in female).

Galileo et al. (2017) described O. clarkei based on a series of specimens, males and females, from Bolivia, but did not compare this species with O. advena , which is very similar in general appearance. Males of O. advena ( Fig. 9 View FIGURES 9–16. 9–13 ) differ from those of O. clarkei ( Fig. 16 View FIGURES 9–16. 9–13 ) by the shorter antennae, two times elytral length, reaching elytral apex at middle of antennomere VII (about 2.5 times elytral length, reaching elytral apex at distal third of antennomere VI in O. clarkei ), but especially by the basal crest not strongly sinuous dorsally, and the two more elevated area on top of the crest not projected forward as carina ( Fig. 13 View FIGURES 9–16. 9–13 ) (basal crest strongly sinuous dorsally, and each more elevated area on top distinctly projected forward as carina in O. clarkei ( Fig. 14 View FIGURES 9–16. 9–13 )).
