Description. Male. Body slender, with weak greasy shine. Apex of frontoclypeus (frontoclypeal tooth) acute, vertically projected. Anterior margin of frontoclypeus separated from the other surface of head by wide transverse protuberance, which is separated from the other surface of head by deep transverse depression. Lateral margin of head irregularly weakly rounded, sinuated. Genae weakly emarginate. Supraocular keels extended almost from level of basal margin of eye. Head surface with wide transverse depression on each side between frontoclypeus and anterior margin of supraocular keels. Head widest at eye level. Ratio of head width at eye level to distance between eyes 1.5. Antennae short, with apical antennomere reaching basal third of pronotum. Ratio of length (width) of antennomeres II–XI: 0.6(0.5): 0.6(0.4): 0.8(0.5): 0.7(0.4): 0.6(0.4): 0.6(0.4): 0.7(0.5): 0.5(0.5): 0.5(0.5): 0.3(0.4). Punctation of head moderately coarse and sparse, puncture diameter 1.5–2.0× as wide as distance among punctures. Vertex with deep transverse depression, shiny, with coarse and dense rasp-shaped punctation (puncture diameter 1.5–2.0× as wide as distance among punctures). Mentum weakly shiny, moderately coarsely and densely punctate by rasp-shaped punctures (puncture diameter 1.5–2.0× as wide as distance among punctures).

Pronotum transverse (1.2× as wide as long), widest little before middle, 1.2× as wide as head. Ratio of pronotal width at anterior margin, in middle and at base 5.5: 7.0: 6.5. Anterior margin of pronotum widely emarginate, base bisinuate, weakly rounded in middle. Lateral margins of pronotum weakly rounded, slightly sinuated at base. Anterior angles of pronotum acute, narrowly rounded at apex, basal angles obtuse. All margins of pronotum beaded. Disc of pronotum moderately convex, without depressions in basal part. Disc of pronotum with fine, moderately dense punctation. Prothoracic hypomera completely punctate with moderately coarse, dense rasp-shaped punctures (puncture diameter 1.5–2.0× as wide as distance among punctures). Prosternal process laminar, strongly protruded, laterally acute, completely beaded, with longitudinal depression and very fine, moderately dense punctation.

Elytra smooth, with only fine microwrinkles, moderately elongate (1.6× as long as wide), slightly convex, 2.1× longer and 1.6× wider than pronotum, 2.0× wider than head. Elytra without striae, with fine, moderately dense punctation. Epipleura with poorly visible transverse wrinkles. Mesoventrite with mainly bisinuate bracket- shaped deep foveae. Metaventrite with poorly visible wrinkles and fine, moderately dense weakly rasp-shaped punctures along mesocoxae, remaining surface of metaventrite smooth.

First abdominal ventrite moderately coarsely and densely punctate by large round punctures along basal margin of metacoxae (puncture diameter 1.5–2.0× as wide as distance among punctures), remaining ventrites with smooth punctures on sides and very fine, sparse punctures middle. Only abdominal ventrite 1 completely laterally beaded, ventrite 2 beaded on less than half its surface, ventrites 3–5 not beaded.

Legs short. Anterior tibiae not depressed along dorsal surface of outer margin. Pro- and mesotibiae straight, metatibiae slightly concavely curved. Ratio of femur/tibia/ tarsus 3.0: 3.5: 3.0 in fore legs, 5.0: 4.0: 3.0 in middle legs, and 6.0: 5.0: 4.0 in hind legs.

Body length 12.0 mm, width 4.5 mm.

Female. Body more robust. Elytra 1.3–1.45× as wide as long.

Variability. Specimen from Berçelan Yayla differs in finer and sparser punctation of pronotum (puncture diameter 1.5–2.0× as long as distance among punctures; prosternal process moderately protruded (not laminar), rounded, laterally rectangular; elytral punctation very fine and sparse (puncture diameter 3.0–4.0× shorter than distance among punctures). Ovipositor of females in all populations has the same structure.

Etymology. The species is named in honour of Ottó Merkl (HNHM), who continuously and greatly helps us with the provided material.

Distribution. South-Eastern Turkey, North-Western Iraq.

Comparative diagnosis. The new species belongs to the species-group with beaded anterior margin, head separated from the other surface by transverse convexity. Externally C. ottoi sp. nov. is similar to C. gigas Kaszab, 1962 from Lorestan ( Iran) in form of its body, punctation of the pronotum and prothoracic hypomera but clearly differs from it in the head sculpture. Calyptopsis ottoi sp. nov. has sharply beaded and elevated anterior margin of the head, which is separated from the other surface by deep depression, while C. gigas possesses smooth beaded and not elevated anterior margin of the head, which is not separated from the other surface by transverse depression. The sharply beaded and separated anterior margin of head can be found also in C. theodoridesi Kaszab, 1962 and C. harpaloides Baudi di Selve, 1874 . The first species differs from C. ottoi sp. nov. in robust body with very large pronotum 1.8× shorter than elytra, the second one differs in flattened and robust wide body, and emarginate near base lateral margins of pronotum. The new species has pronotum 2.20–2.35× shorter than elytra. From both species C. ottoi sp. nov. also differs in the presence of distinct round impression in the middle of the frons.
