Description. Male (holotype). Body medium stout, subparallel. Head: rostrum moderately stout, medium long (l/ w 4.05, Rl/Pl 1.08), dark brown, apical part lighter; in lateral view slightly evenly curved, same width from base to antennal insertion, then slightly apically tapered, at antennal insertion upper margin slightly elevated forming indistinct swelling; in dorsal view slightly broadened to antennal insertion, then parallel-sided until apex, at base moderately laterally constricted, beyond antennal insertion dorsoventrally flattened; very densely, longitudinally punctured, punctures, especially in basal half, sometimes confluent, very close to apex with smooth shiny triangular area; basal part covered with recumbent to subrecumbent, backwardly oriented, elongate whitish scales, apical part with suberect, forwardly oriented, long, whitish seta-like scales. Head between eyes narrow, of about 0.3 rostrum width at base. Eyes large, rounded, not protruding from head outline. Antennae reddish-brown with darkened club, inserted at 0.7 of rostrum length; funicle of about 0.8 scape length, segment 1 wider, 1.4 × as long as segment 2, segment 1 almost twice as long as wide, segment 2 slightly more than twice as long as wide, segments 3–4 slightly longer than wide, segment 5 as long as wide; club oval, about 2.3 × as long as wide, of about 0.7 funicle length, densely covered with whitish, tiny thin setae and a few long erect whitish sensilla. Pronotum: brown, markedly wider than long (Pl/Pw 0.58), with very densely arranged subrotund punctures, densely covered with subrecumbent to suberect, variously oriented yellowish elongate (l/w 5–7) scales leaving integument partially visible; in basal half broadly rounded, widest between 1/4 and 1/3 of its length, then shortly conically narrowed to anterior margin, convex on disc, in lateral view with nearly straight basal third, then falling to anterior margin. Prosternum: anterior margin with deep, sharply incised subrotund emargination not reaching coxae. Scutellum: blackish-brown, triangular with rounded apex, evenly covered with backwardly oriented, tiny, thin whitish scales. Elytra: brown, at sides very slightly rounded, moderately elongate (El/Ew 1.25), widest at about 1/3 of their length, at base markedly wider than pronotum (Ew/Pw 1.76), humeri moderately prominent, broadly rounded; slightly convex to flat on disc; interstria 1 strongly broadened in about 1/3 of medial length and very close to apex encompassing relatively large black tomentous round maculae with border formed by sparsely arranged yellowish to gingery scales, interstria 2 at same lengths constricted laterally and considerably narrowed, interstriae vaulted, of approximately equal width; odd interstriae with unevenly distributed patches of clustered yellowish elongate scales, without black patches; striae shallow, formed by very dense, unevenly large and shaped punctures; entire surface except maculae covered with tiny, strongly elongate (l/w 5–9), recumbent, whitish scales concealing more than half of integument. Venter: in longitudinal median part sparsely covered with backwardly oriented, thin, long, whitish scales, at sides, especially of mesosternum, metasternum, metepisternum and margins of all ventrites except ventrite 5 with very densely arranged, partially overlapping, elongate yellow to light brown scales; mesosternal process short, with almost straightly truncated apex; metasternum concave with transverse ribs and scattered punctures; ventrites 1 and 2 with median longitudinal broad deep impression; ventrite 1 twice as long as ventrite 2, ventrites 1–2 combined 4.6 × as long as ventrites 3–4 combined, ventrites 3–4 combined of 0.6 length of ventrite 5. Legs: brown, onychia lighter except their apices; profemora with relatively large and sharp, laterally protruding teeth, meso- and metafemora with triangular large sharp teeth; femora, tibiae and tarsi except onychia covered with subrecumbent whitish and yellowish elongate scales, tibiae at lateral edges moreover with short suberect black seta-like scales, onychia with scattered subrecumbent whitish very long hairs; protarsal onychia very long, of about 1.5 length of tarsomeres 1–3 combined. Protarsal lateral claws present only as very small tubercles in mid-length of medial claw, meso- and metatarsal medial claws by about 1/3 shorter than their pair-claws. Penis: Figs 34 d–f, its body with broadly tapered apex, in lateral view straight.

Female. Rostrum slightly longer (Rl/Pl 1.37), elytra on average slightly broader (El/Ew 1.20). Ventrites 1 and 2 without impression. Protarsal onychia short, of about 0.8 length of tarsomeres 1–3 combined. Claws of distinctly unequal length, protarsal lateral, meso- and metatarsal medial claws by 1/4–1/3 shorter that their pair-claws.

Variability. Length: ♂♂ 4.05–4.75 mm, ♀♀ 4.40–4.88 mm. The type series shows slight variability. In some specimens the integument may be reddish-brown and/or the apices of onychia are feebly darkened, the profemoral teeth are sometimes smaller but always sharply laterally protruding.

Diagnosis. This species is characterised by large body size, rounded pronotum, protruding profemoral teeth, distinctly unequally long claws in both sexes, in males by very long protarsal onychia and broadly tapered straight apex of the body of penis.

Comparative notes. Cionus winkelmanni differs from the most closely related C. balianii by larger body size and markedly longer male protarsal onychia, from C. ungulatus by larger body size and straight apex of the body of penis. From all species of the group it differs by sharp laterally protruding teeth on profemora in both sexes and distinctly unequally long claws in females.

Biological notes. This species develops very probably in Scrophularia sp. It was collected on this plant genus by Winkelmann and Lodos, the former collector reporting the elevation 1,800 –2,000 m a. s. l. (label data).

Distribution. Turkey.

Etymology. We devote this species to our colleague and friend, an experienced entomologist specialized in weevils, Herbert Winkelmann, who pointed out peculiar characters of this species on labels of some paratype specimens.

Non-type specimens examined. None.
