Description. Male holotype. Body length 5.4 mm. Body elongate, integument shiny, head black, pronotum dark brown, elytra brownish-black, legs and antennae reddish-brown (Figs 1 e–f).
Head. Head and rostrum approximately as long as pronotum (HL+RL/PL 0.97), rostrum moderately stout, between pterygia and eyes subparallel-sided, slightly longer than wide (RL/RW 1.16), 1.9 times longer than head, entire rostral surface with moderately dense, recumbent, elongate, intermixed metallic greenish-yellowish-pinkish hair-like setae, apex with sparse, short, yellowish epistomal setae. Pterygia strongly projecting, epistome moderately densely and shallowly punctate, surrounded by flat, scarcely visible, semicircular carina, epistomal angles moderately strongly elevated, as a result small horns developed, dorsal wall weakly punctate with conspicuous longitudinal keel. Epifrons parallel-sided, with shallow, almost flat median sulcus, median keel not developed, median sulcus covered with moderately dense large punctures and elongate, intermixed yellowish-pinkish bristles with metallic shine directed backwards, around eyes scarcely wrinkled. Eyes large, moderately convex, forehead relatively broad, almost flat, moderately densely and coarsely punctate, weakly wrinkled. Head capsule elongate, tapering and with scarcely visible interocular pit, vertex moderately convex, finely punctate, interocular distance 2.28 times as wide as epifrons at its narrowest point. Scape moderately stout, slightly curved, gradually widened from base toward apex, sparsely covered with thin, elongate and recumbent golden setae, funicle segments covered with elongate, semierect, pale brown setae, segment 1 stout, 1.83 times as long as wide and a bit longer than segment 2 (1.18 times longer than segment 2), which is 2.6 times longer than wide, 3 elongate, 4–7 wider than long, more globose, club oblong-oval, covered with dense whitish recumbent hairs, basal part with sparse, longer, erect, pale brown hairs.
Pronotum. As long as wide (PL/PW 1.02), widest in middle, regularly rounded. Disc covered with dense fairly coarse punctures, interspaces broad, flat, shiny, slightly confluent. Sides of pronotum with quite flat, small, umbilicate granules. The granules on the sides and punctures on the dorsum with elongate, intermixed metallic greenish-yellowish-pinkish hair, interspaces of the granules on the sides and posterior margin of the dorsum with elongate, intermixed metallic greenish-yellowish-pinkish scales.
Elytra. Elongate 1.77 times longer than wide, widest at anterior third, longitudinally flat, steeply declined to posterior end. Base as wide as base of pronotum. Striae well-visible, punctures deep, rounded, interspaces shorter than punctures diameter, with flat, hardly visible granules. Each puncture with hardly visible, short, recumbent, whitish hair directed backwards, interspaces with granules and moderately dense scales. Scales fairly broad, apically pointed to truncate, intermixed greenish-yellowish-pinkish with metallic lustre. Interstriae clearly narrover than striae, slightly convex, with small, almost flat granules. Granules of the sides and posterior half more convex, scarcely wrinkled, on the dorsum with well-visible recumbent, hair-like, metallic yellowish setae directed backwards in regular rows, longer than interspaces between them.
Legs. Femora moderately stout, profemora scarcely swollen, with small, acute teeth and with metallic yellowish, hair-like setae. Tibiae moderately stout, dorsal margin of protibiae straight, ventral margin scarcely arched and denticulate, slightly widened at apex. Apex of all tibiae with acute mucro, and metallic whitish-yellowish hair-like setae, mainly ventral margin of hind tibiae with scattered, small granules. Apical setal comb yellow. Protarsomeres 1-2 triangular, 3 wide and bilobed, shorter than 1 and 2 combined, 5 almost 2 times as long as 3.
Venter. Mesanepisternum finely microsculptured and with sparse, shallow punctures, metanepisternum, mesepimeron, metaventrite and abdominal ventrites 1-5 covered with scattered, small flat, hardly visible granules, scarcely punctate. Abdominal ventrites 2-5 densely and shallowly punctate. Venter covered with relatively dense, intermixed metallic yellowish-greenish-pinkish hair and narrow, elongate scales. Ventrite 5 regularly rounded apically.
Male terminalia (Figs 4 j–l, n, p). Pygidium truncate, with dense, short, pale hair at apex and with dense shallow punctures. Spiculum gastrale almost straight (Fig. 4 n). Penis relatively slender (Figs 4 j–k), median lobe subparallel-sided, slightly tapering along apical third (Fig. 4 l), about as long as apodemes. In lateral view (Fig. 4 k) widened to basal half. Internal sack with basal sclerite. Tegminal-ring (Fig. 4 p) oval, with fairly short parameres, manubrium slightly curved, laterally scarcely flattened, about as long as apodeme of median lobe.
Female (Figs 1 g –h). Very similar to male, the body scarcely larger, legs and protarsomeres 1-3 slightly narrower.
Female genitalia (Figs 5 b, d). 8 th sternite narrow, apodeme slender, apical margin excised out triangularly, sclerotised, with several long sensillae at apex (Fig. 5 b). Spermatheca fairly stout, with short, C-shaped cornu apically pointed, ramus small, collum short (Fig. 5 d). Ovipositor with long styli and long sensillae.
Variability. Male: BL: 5.1–6.2 (average 5.5), BW: 1.9–2.2 (average 2.0), BH: 1.5–1.7 (average 1.6). Female: BL: 4.8–5.7 (average 5.2), BW: 1.8–2.2 (average 2.0), BH: 1.4–1.6 (average 1.5). The specimens examined are morphologically quite uniform although their colour is quite variable, often with the whole body brown, probably due to specimens being freshly emerged. Only occasionally are specimens are entirely black. Occasionally, the interspaces of punctures on the pronotal disc appear as irregular fairly large and fairly convex umbilicate granules.
Remarks and comparative notes. Otiorhynchus roznerantii clearly differs from other species of Anchorrhynchus with an impunctate pronotum. A few specimens of O. roznerantii which display an irregularly granulate pronotal disc differ from similar species (Otiorhynchus endroedii, O. maderi maderi, O. maderi dajtitensis, O. muellerorum) in the structure of antennae: funicle segments 4-7 which in O. roznerantii are transverse whereas in O. endroedii segments 3-4 are elongate, 5 isodiametric, 6-7 elongate; in O. maderi maderi segment 3 is elongate, 4 isodiametric, 5 transverse, and 6-7 isodiametric; in O. muellerorum funicle segments 3-7 are elongate. Otiorhynchus maderi dajtitensis differs in a glabrous, or almost glabrous body.
Distribution. Greece, North-Macedonia.
Etymology. The specific epithet is a patronym in honor of Rozner Antal (Anti to his friends) of Budapest, Hungary, who supported the Macedonian collecting trips.
