(Figures 3 a–d)
Description. Male. Length 9.0 mm (measured from vertex to elytral apices), width 2.8 mm (measured across humeri). Habitus as in Fig. 3a. General form moderately elongate. Integument mostly reddish brown; head (except brownish labial and maxillary palpomeres), scape, pedicel, prothorax dark brown; antennomeres III–XI slightly darkened at apex; abdominal ventrites reddish-orange; meso- and metafemora reddish brown basally, darker toward apex; base and apex of tibiae darker.
Head. Frons slightly longer than wide, subquadrate; coarsely, sparsely punctate, especially in central area near clypeus; with abundant yellowish pubescence, slightly lighter, partially obscuring integument near eyes. Vertex with yellowish pubescence. Antennal tubercles divergently elevate, modified at inner side (horn-shaped). Median groove distinct from clypeus to prothoracic margin. Genae about 0.8 times of lower eye lobe length; moderately densely punctate; yellowish pubescence as on frons. Distance between upper eye lobes about twice greatest width of one upper lobe eye. Left antenna damaged (missing antennomeres IX–XI), right antenna reaching elytral apex at midlength of VII. Scape gradually widened toward apex; with a few rough spots and a few brownish erect setae at base of inner side; with moderately abundant yellowish pubescence on base, whitish-yellow in remaining areas, not obscuring integument. Pedicel and remaining antennomeres with whitish-yellow pubescence, not obscuring integument, and a few brownish erect setae on inner side. Antennal formula based on antennomere III: scape = 1.00; II = 0.13; IV = 0.85; V = 0.86; VI = 0.84; VII = 0.80; VIII = 0.72; IX = 0.65; X = 0.64; XI = 0.84 (slightly curved).
Thorax. Prothorax transverse, about 1.4 times as wide as long (including tubercles); sides with tubercle about middle, conical and blunt at apex; posterior half remarkably narrowed, with a few erect brownish setae. Pronotum with basal and distal sulci distinct; pronotal disk with three slightly elevate tubercles, two anteriorly, another centrally; surface with moderately dense yellowish-white pubescence forming median line, not obscuring integument (tubercles glabrous). Prosternum and mesoventrite with yellowishwhite pubescence nearly obscuring integument, more yellowish toward sides and anteriorly. Prosternal process strongly triangle-shaped. Mesepisternum with yellowish pubescence not obscuring integument. Mesosternal process slightly longitudinally depressed; about as wide as half mesocoxal cavity; truncate apically. Metepisternum with yellowish-white pubescence, yellower on anterior margin; metasternum with dense yellowish-white pubescence, nearly obscuring integument (except glabrous, central, inverted triangle-shaped area), and yellower pubescence on posterior sides. Scutellum about 1.3 times wider than long, with sparse yellowish-white pubescence; rounded posteriorly. Elytra. About 2.3 times humeral width, 4 times as long as prothoracic length; apical quarter slightly convergent; apices rounded together; surface coarsely, moderately abundantly punctate in anterior half, punctures gradually sparser in posterior half; with a few granulate punctures near scutellum; with dense yellowish-white pubescence between humeri, nearly obscuring integument, sparser in remaining areas (except glabrous areas around punctures); with yellowish spots throughout. Legs. Coxae with dense yellowish-white pubescence, sparser on mesocoxae; femora with moderately yellowish-white pubescence; profemora with irregular wrinkles in basal third. Tibiae with mostly yellowish pubescence, lighter on base. Metatarsomere I about 0.7 times II–III together. Abdomen. Ventrites with dense yellowish-white pubescence, partially obscuring integument; apex of ventrite V slightly notched with brownish elongate setae.
Female. Unknown.
Type material. Holotype (Fig. 3 a–d) male from PERU, La libertad (Sánchez Carrión prov., Road PE 10C, near Laguna Pias, 07º54′43″ S 77º35′38″ W, 2,180 m), 19.X.2011, V. Sinyaev col. (MZSP).
Etymology. The new species is named in honor of the great beetle collector Anton Olegovich Kozlov (Moscow, Russia), who donated the holotype. The epithet is a noun in the genitive case.
Diagnosis and remarks. Oncideres antonkozloƲi sp. nov. is similar to O. pectoralis Thomson, 1868 by the pronotum and pattern of elytral pubescence. The new species can be separated especially by the antennal tubercles modified at inner side (horn-shaped), and sparse whitish pubescence between the yellowish spots of the elytra. In O. pectoralis the antennal tubercles are not modified, and the pubescence between the elytral spots is yellowish, forming dense areas nearly obscuring integument.
