(Figs. 5-8)
Description: Female. Color. Head dark brown, almost black; prothorax black centrally, slightly dark brown toward anterior and posterior margins; scape and pedicel black; antennomeres dark brown,slightly, gradually lighter toward antennomere VI (missing antennomeres VII‑XI of left antenna, and VI‑XI of right antenna); ventral side of meso‑ and metathorax dark brown, slightly reddish on central apex of metaventrite; femora dark brown except reddish‑brown basal area; tibiae and tarsi dark brown; abdominal ventrites dark brown except reddish‑brown centro basal area of ventrite I. Anterior ⅔ of elytra dark brown (forming darker band around light areas) except two large yellowish‑white maculae: one subelliptical,oblique, starting at about anterior eighth of dorsal surface, ending near lateral margin slightly after apex of anterior third; another oblique, placed about midlength, projected forward along suture, ending near lateral margin. Posterior third of elytra reddish brown except apex yellowish‑brown and dark brown band between these two areas.
Head: Frontal plate very finely, obliquely striate, divided by moderately deep, oblique sulcus on each side of median groove; with longitudinal sulcus laterally between frontal plate and lower eye lobes; finely, moderately abundantly punctate centrally toward antennal tubercles; with short, erect, sparse brownish setae close to eyes, glabrous on remaining surface. Area between antennal tubercles shallowly, moderately finely punctate; glabrous. Area between upper eye lobes with U‑shaped, slightly elevated carina; finely, moderately abundantly punctate close to eyes, smooth on remaining surface; surface glabrous. Remaining surface of vertex minutely, densely punctate except area close to prothorax finely, moderately sparsely punctate; area minutely punctate with yellowish‑brown pubescence not obscuring integument centrally, more yellowish‑white laterally; area close to prothorax nearly glabrous. Area behind upper eye lobes sulcate close to eye, minutely, densely punctate between sulcus and finely, moderately sparsely punctate area close to prothorax; with moderately dense yellowish‑white pubescence close to eye, glabrous close to prothorax; with a few long, erect yellowish‑setae close to eye. Area behind lower eye lobes tumid, finely, moderately abundantly punctate close to eye, nearly smooth on remaining surface; with sparse, erect, yellowish setae on tumid area, glabrous on remaining surface. Genae minutely, densely punctate except smooth distal area; with minute, sparse, decumbent yellowish setae except glabrous smooth area. Median groove distinct from oblique sulcus of frontal plate to area between upper eye lobes (carinate between antennal tubercles and eyes). Postclypeus nearly glabrous except a few short, erect, yellowish setae on sides of wide central area, interspersed with one long, erect setae of same color on each side. Labrum coplanar with anteclypeus on posterior third, inclined on anterior ⅔; with long, erect, nearly golden setae, especially laterally. Gulamentum smooth and glabrous on posterior third, tumid, moderately finely punctate on anterior ⅔; glabrous on smooth area, with long, erect and decumbent, moderately yellowish setae on tumid area. Distance between upper eye lobes 0.26 times length of scape; in frontal view, distance between lower eye lobes 0.62 times length of scape; upper eye lobes with three rows of ommatidia; connection between eye lobes with row of one ommatidium. Antennae almost reaching posterior third of elytra (apex of antennomere VI); scape with yellowish‑brown pubescence not obscuring integument, interspersed with a few long, erect yellowish setae, except glabrous distal area; pedicel and antennomeres with yellowish‑white pubescence not obscuring integument, and long, erect yellowish setae ventrally, sparser toward antennomere VI; antennal formula (ratio) based on antennomere III: scape = 0.68; pedicel = 0.12; IV = 0.75; V = 0.85; VI = 0.81.
Thorax: Prothorax cylindrical, 1.5 times longer than wide; sides bigibbous centrally; anterior and posterior constrictions well‑marked. Pronotum with five large gibbosities between anterior and posterior constrictions, one anterior and one posterior subcircular gibbosity on each side, another subelliptical centrally; somewhat rugose centrally, including part of central gibbosity; coarsely, very sparsely punctate; posterior sulcus well‑marked; with grayish‑white pubescence not obscuring integument,distinctly sparser close to anterior margin, denser, yellower centrally between lateral gibbosities of posterior area, between lateral gibbosities, and on area of anterior constriction; with long, erect,sparse yellow setae.Sides of prothorax with dense yellowish‑white pubescence on posterior ⅔ (more whitish depending on light intensity), nearly glabrous on anterior third (this area widened toward ventral side); with a few long, erect, yellowish setae. Prosternum moderately coarsely, sparsely punctate on posterior half, finely, transversely, finely striate on anterior half; with moderately dense grayish‑white pubescence on posterior half, interspersed with long, erect yellowish setae, glabrous on anterior half.Mesoventrite with very sparse grayish‑white (more yellowish depending on light intensity) pubescence centrally, denser laterally; mesanepisternum, mesepimeron, and metanepisternum with grayish‑white pubescence partially obscuring integument (more yellowish depending on light intensity). Mesoventral process centrally emarginate at apex, with apical sides projected under mesocoxal cavities. Metaventrite with grayish‑white pubescence, denser close to metacoxae (more yellowish depending on light intensity). Scutellum with yellowish‑white pubescence not obscuring integument. Elytra: Finely, sparsely punctate; with minute, very sparse yellowish‑white setae interspersed with long, erect yellowish setae throughout, more abundant on distal half; apex obliquely truncate, with long spine at outer angle, and rounded sutural angle. Legs: Missing protarsi, right middle leg, and left metatarsomeres III‑V. Femora and tibiae with grayish‑white pubescence partially obscuring integument, interspersed with long, erect yellow setae, denser, bristly on ventral side of distal third of tibiae.
Abdomen: Ventrites with grayish‑white pubescence partially obscuring integument; ventrites III‑V with a few long, erect yellowish‑brown setae; apex of ventrite V rounded.
Dimensions (mm): Total length, 12.25; prothoracic length, 2.50; anterior prothoracic width, 1.35; posterior prothoracic width, 1.60; widest prothoracic width, 1.65; humeral width, 2.15; elytral length, 7.60.
Type material: Holotype male from COLOMBIA, La Guarija: Carretera Via Palomino‑Mingueo (Cabañas El Bosque; 55 m; 11°13’00”N, 73°28’29”W), no date indicated, Sinyaev col. (MZSP, former AKPC).
Etymology: The new species is named to honor Anton Olegovich Kozlov, who sent the specimens for study, and donated the holotype for the MZSP collection.
Remarks: Ophtalmibidion antonkozlovi, sp. nov., is similar to O. auba Martins & Galileo, 1999, but differs as follows: antennae and legs dark (from black to dark‑brown); anterior half of the elytra dark brown between light areas; anterior third of the elytra without oblique pale yellow macula; outer angle of the elytral apex spiniform. In O. auba, the antennae and legs are yellowish‑brown, anterior half of the elytra is yellowish‑brown between the light areas, anterior third of the elytra with oblique pale yellow macula, and the outer angle of the elytral apex is slightly projected.
