Head: Frons and vertex coarsely, abundantly punctate, punctures mostly anastomosed, mainly on wide area close to upper eye lobes, except smooth, triangular, central area close to clypeus; with short, sparse, erect, yellowish setae. Area behind upper eye lobes coarsely, anastomosed punctate on region closer to vertex, finely, densely asperate toward lower eye lobes; with short, sparse, suberect, yellowish setae close to eye, glabrous on remaining surface. Area behind lower eye lobes finely, densely asperate on basal 1/3, striate-punctate on remaining surface, except narrow area close to eye with moderately coarse, confluently punctures; with suberect, short, yellowish setae close to eye, sparser toward ventral side. Antennal tubercles slightly elevated; coarsely, confluently punctate on base, moderately finely, confluently punctate toward apex, then finely, densely punctate toward antennal socket; with short, erect, sparse, yellowish setae, more abundant on area closer to antennal socket.

Antenna 0.55 times elytral length, reaching apex of basal 1/5 of elytra. Scape curved, enlarged toward apex, reaching about middle of upper eye lobe; in frontal view, distinctly sloped dorsally and ventrally toward narrow margin; dorsally finely, abundantly punctate, except on area closer to inner margin; ventrally finely, moderately abundantly punctate, gradually sparser toward subsmooth area close to inner margin. Antennal formula (ratio) based on antennomere III: scape = 1.92; pedicel = 0.48; IV = 1.08; V = 1.08; VI = 1.08; VII = 1.16; VIII = 1.04; IX = 1.00; X = 1.00; XI = 1.40. Thorax: Prothorax transverse (1.3 times wider than long, excluding lateral tubercle). Lateral margins of pronotum with spiniform, long tubercle at basal 1/4, parallel-sided, crenulate between this tubercle and anterolateral angle, oblique, finely crenulate between posterolateral angle and tubercle; anterolateral angle projected forward, slightly projected; discal plate shiny, goblet-shaped, coarsely, abundantly punctate close to anterior margin, sparser toward narrowed region of plate, distinctly coarser, confluent on narrowed region of plate (mainly laterally), finer, sparser toward base (mainly laterally); sides opaque, except some small, irregular, shiny areas, coarsely, anastomosed punctate; shiny plate glabrous, except for short, erect, yellowish setae emerging from punctures close to anterior margin; opaque area with long and short, erect, yellowish setae (longer near base). Hypomeron distinctly narrowed after procoxal cavity. Notosternal suture uniformly curved from procoxal cavity to anterior margin. Prosternum coarsely, anastomosed punctate (coarser laterally); with long, suberect, sparse, yellowish setae (more abundant on anterior third). Prosternal process centrally and distally shiny, slightly elevated (more tumid toward apex); laterally opaque, sulcate; apex distinctly narrowed, subconical. Mesosternum finely rugose, opaque laterally (less so toward apex); centrally carina-shaped, shiny; with long, erect, moderately abundant yellowish setae. Mesosternal process distinctly elevated laterally; centrally slightly carina-shaped (continuing that on mesosternum); finely rugose on each side of central carina, finely, abundantly punctate toward sides; apex distinctly emarginate; with long, erect, yellowish setae on basal half, sparser, shorter toward apex. Mesepimeron and mesepisternum minutely, abundantly asperate; with long, abundant, yellowish setae. Metepisternum finely, densely punctate; with long, abundant, erect, yellowish setae (not obscuring integument). Metasternum opaque, finely, densely punctate laterally, shiny, finely, moderately sparsely punctate on subtriangular central plate; with long, erect, abundant yellowish setae on opaque region (not obscuring integument), sparser on shiny region. Scutellum minutely, densely punctate on sides of base, finely, sparsely, abundantly punctate laterally and distally (except smooth narrow band close to apex), subsmooth centrally; with short, sparse, yellowish setae on punctate area. Membranous wing light, translucent ( Fig. 4 ). Elytra: Rugose-punctate throughout; glabrous, except for some short yellowish setae laterally near humerus; sides subparallel at distal 2/3, gradually rounded on distal 1/3; apex with distinct spine at sutural angle. Legs: Femora finely, sparsely punctate (punctures coarser toward ventral side); with short and long, sparse, yellowish setae. Protibia coarsely, moderately abundantly punctate (mainly dorsally); outer side with distinct spines; with short, sparse, yellowish setae, distinctly more abundant at distal 1/3 of inner side. Mesotibia with short, distinct spines at distal half of dorsal surface; punctures and setae as on protibia. Metatibiae without spines, punctures and setae as on protibia. Abdomen: Ventrites I – IV finely, sparsely punctate centrally, densely asperate-punctate laterally; with long, subdecumbent, sparse, yellowish setae on central area, distinctly more abundant laterally. Ventrite V finely, moderately abundantly punctate, except finely asperate central region; with long, suberect, moderately sparse, yellowish setae; apex slightly rounded.

Measurements. Total length (including mandibles) 35.1 mm; prothoracic length 6.0 mm; anterior prothoracic width 7.9 mm; posterior prothoracic width 7.7 mm; widest prothoracic width (between apex of lateral tubercles) 9.8 mm; humeral width 10.6 mm; elytral length 23.9 mm.

Type Material. Holotype female from COLOMBIA, Antioquia: Municipio de Yarumal (Vereda Ventanita ; 2020 m; 79°04 ′ 05 ′′ N / 75°26 ′ 59 ′′ W), 9-14. IV.2015, Synyaev, M. Márquez & J. Machado col. (MZSP).

Etymology. This new species is named after Anton Olegovich Kozlov, who sent and donated the specimen.

Remarks. The female of P. antonkozlovi is similar to that of Physopleurus longiscapus Lameere, 1912 and Physopleurus rugosus (Gahan, 1894) by the elytra with a rugose appearance. It differs from the former by the scape reaching the middle of the eye ( Fig. 1 ), the distinctly larger eyes ( Figs. 1, 2 ), and the prosternum distinctly more abundantly punctate ( Fig. 2 ). In females of P. longiscapus, the scape reaches the posterior margin of the eye ( Fig. 8 ), the eyes are smaller ( Figs. 8, 9 ), and the prosternum is finely, sparsely punctate ( Fig. 9 ). Females P. antonkozlovi can be separated from females of P. rugosus by the upper eye lobes notably larger, the prosternum distinctly more punctate, and the membranous wings light and translucent. In females of P. rugosus, the upper eye lobes are distinctly smaller ( Fig. 6), the prosternum is finely and sparsely punctate ( Fig. 7 ), and the membranous wings are somewhat translucent, but distinctly darkened ( Fig. 5 ).
