(Fig. 1–8)
Description. Holotype male (Fig. 1–3). Integument dark-brown, except for: central area of metathorax, close to metacoxae, orangish-brown; black narrow band on lateral and apex of ventrites; antennomeres reddish-brown (lighter towards distal antennomeres), with dark apex; one each elytron two yellow callosities, one transverse, about middle, another smaller, more rounded, placed on distal third.
Head. Frons large; finely, densely punctate throughout; with short, abundant setae. Area between antennal tubercles and upper eye lobes finely, densely punctate close to antennal tubercles, coarser, sparser towards coronal suture; narrow area close to coronal suture smooth; area between base of antennal tubercles and posterior edge of upper eye lobes depressed, with short, moderately sparse setae. Antennal tubercles finely, densely punctate; with short, abundant setae. Dorsal area between eyes and anterior edge of prothorax with two types of punctures: moderately coarse on two-thirds closer to the eyes, sparser close to coronal suture; microsculptured on third closer to prothorax; area coarser punctate with short setae, laterally distinctly more abundant, interspersed with long, sparse setae close to eyes. Coronal suture distinct from clypeus to middle of area between eyes and prothorax; on frons placed on longitudinal elevation. Ocular carina narrow, well-marked from antennal tubercle to posterior edge of upper eye lobe. Area behind upper eye lobes moderately coarsely, abundantly punctate on region closer to eyes, gradually narrowed towards area of connection of ocular lobes; remaining surface microsculptured. Area behind lower eye lobes microsculptured, interspersed with shallow, coarse punctures on half closest to the eye. Genae finely, abundantly punctate, except for anterior edge smooth. Distance between upper eye lobes equal to 0.6 times length of scape; distance between lower eye lobes equal to 1.2 times length of scape. Mandibles coarsely, confluently punctate on dorsal and lateral sides. Submentum well-marked, microsculptured, interspersed with coarse, abundant punctures; sloped towards anterior carina; with moderately short, sparse setae. Antennae as long as 2.7 times elytral length, reaching elytral apex about distal third of antennomere VII; antennal formula (ratio) based on antennomere III: scape = 0.57; pedicel = 0.2; IV = 0.77; V = 0.80; VI = 0.80; VII = 0.71; VIII = 0.57; IX = 0.60; X = 0.60; XI = 0.56; XII = 0.69.
Thorax. Disc of pronotum shiny, glabrous, finely, sparsely, shallowly punctate. Lateral sides of prothorax glabrous. Anterior impunctate third of prosternum centrally with long, sparse setae. Prosternal process coarsely, abundantly punctate on subhorizontal area, except for narrow distal region, shallowly, sparsely punctate on vertical area. Metasternum microsculptured, laterally interspersed with fine, moderately abundant punctures, gradually sparser towards middle; glabrous, except for short, sparse setae close to ventrite I, distinctly longer near metacoxae. Scutellum glabrous. Elytra glabrous, finely, sparsely, shallowly punctate; outer apical angle rounded; sutural angle sub-rounded.
Abdomen. Ventrites I–IV finely, sparsely punctate; with short, sparse setae, slightly longer and more abundant on center of ventrite I; distal third of ventrite V fine, but distinctly coarser, more abundantly punctate than remaining ventrites; with short, moderately sparse setae on punctate area. Legs. Peduncle of femora moderately coarsely, shallowly punctate; metafemora, femoral clubs finely, sparsely punctate.
Female (Fig. 4–6). Antennae as long as 1.5 times elytral length, reaching about elytral apex; antennal formula (ratio) based on antennomere III: scape = 0.75; pedicel = 0.22; IV = 0.75; V = 0.77; VI = 0.69; VII = 0.60; VIII = 0.45; IX = 0.40; X = 0.38; XI = 0.58. Metasternum centrally with long, sparse setae.
Variability. The callosities of elytra can be brownish. Dorsal area of head, between upper eye lobes sometimes with large smooth or nearly smooth area; dorsal area of head, between upper eye lobes and antennal tubercles with one coarse, deep, elliptical puncture on each side of coronal suture. Frons without central elevation at area of coronal suture. Antennae (Fig 7–8) from 2.4 to 3.0 times elytral length, reaching elytral apex from basal third to distal third of antennomere VII. Inner margin of mandibles not denticulate.
Dimensions in mm (male/female). Total length, 11.90–15.90/13.10; length of prothorax at center, 2.1– 2.7/2.6; anterior width of prothorax, 1.85–2.35/2.05; posterior width of prothorax, 2.30–2.80/2.55; humeral width, 2.85–3.20/3.30; elytral length, 7.30–9.00/8.00. The largest dimensions are those of the holotype.
Type material. Holotype male from PERU, Junin: Satipo (Rio Venado), IX.2014, local collector (MZSP). Paratypes – 3 males (IMCQ), 1 female (MZSP) same data as holotype.
Etymology. The new species is named after René Limoges, entomological technician at IMCQ.
