( Figs 6B,C View Fig , 10F,G View Fig )

Type locality. Turkey, Izmir Province, Bozdağ.

Type material. HOLOTYPE: ♁, ‘ ZDEU 2006 222 // 15.vi.2006 Bozdağ / Izmir / B. Keskin // Calyptopsis Pimeliinae Tenebrionidae B. Keskin det.’ ( ZDEU) . PARATYPE: ♀, same data as holotype ( ZDEU).

Description. Male. Body matt, slender. Body length 12.3 mm, width 4.9 mm. Anterior part of head not sculptured, without coarse bead; anterior margin of frontoclypeus rounded, not vertically projected, without tooth. Head widest at level of lower part of eyes. Head weakly longitudinally depressed along supraorbital keels. Upper half of eyes weakly longitudinal; lower half projected (dorsal view). Ratio of head width at eye level to distance between eyes 1.3. Punctation of head on frons and near eyes moderately coarse and dense (puncture diameter subequal to distance among punctures). Anterior part of head with fine and sparse punctation. Vertex with coarse punctation basally and near eyes. Antennae thin, widened from base to apex. Ratio of length (width) of antennomeres II–XI: 0.6(0.5): 0.9(0.4): 0.7(0.5): 0.7(0.5): 0.7(0.5): 0.7(0.5): 0.6(0.5): 0.5(0.5): 0.5(0.5): 0.4(0.4).

Pronotum widest in middle, 1.52× as wide as head. Anterior margin of pronotum widely and deeply emarginated, base weakly bisinuate. Lateral margins moderately rounded, widely emarginated in basal third. Anterior angles acute, strongly projected; posterior angles right, distinct. Disc of pronotum regularly slightly convex, completely beaded, with fine and sparse punctation (puncture diameter 1.5–2.0× shorter than distance among punctures). Prosternum smooth in middle, without punctation, only with smoothed sparse punctation near anterior margin of procoxae. Prothoracic hypomera completely with smoothed coarse and dense not rasp-shaped punctation (puncture diameter 2.0× as wide as distance among punctures). Prosternal process with longitudinal depression in middle, strongly projected, rectangular (in lateral view).

Elytra elongate (1.4× as long as wide), 1.9× as wide as head, 1.25× as wide and 2.0× as long as pronotum, with matt and weakly shiny areas and the same punctation as on pronotum. Scutellum not reaching outer margin of basal elytral bead.

Mesoventrite with transverse wrinkles in middle and long oblique wrinkles on sides (these wrinkles rasp-shaped, impressed only from inner side), with coarse punctation along anterior margin and very fine and sparse punctation on latero-basal sides. Intercoxal process of mesoventrite smooth. Mesepisterna with large not deep round foveae. Mesepimera and metepisterna with sparse smoothed punctures. Metaventrite with large sparse foveae in anterior 2/3 and rasp-shaped coarse punctures along mesocoxae. Basal part of metaventrite with sparse and fine rasp-shaped punctation.

Lateral margins of first abdominal ventrite completely beaded, of second ventrite beaded only anteriorly.Abdominal ventrites 1–4 with coarse sparse punctation on sides and fine sparse punctation in middle. First abdominal ventrite with very fine and sparse rasp-shaped punctation. Fifth abdominal ventrite with regular fine and sparse punctation and straight truncate apex.

Legs slender, long. Tibiae thin, straight. Protibiae not fossorial, longitudinally depressed on inner side.

Female. Body little more robust.

Etymology. The species is named after Egecem Keskin, the son of the third co-author.

Differential diagnosis. Calyptopsis egecemi sp. nov. is the most similar to C. caraboides (Brullé, 1832) ( Figs 6 View Fig D–G) from Greece but distinctly differs in absence of the frontoclypeal tooth, sculpture of mesoventrite ( C. caraboides has transverse regularly depressed or oval foveae), strongly projected acute anterior angles of pronotum ( C. caraboides has obtuse not projected anterior angles) and thin, regularly widened to apex antennae ( C. caraboides has regularly thickened antennae). Within the Turkish species, C. egecemi sp. nov. can be compared with C. lineimargo , which also has regularly rounded anterior margin of head without vertical border, but clearly different from it in the structure of thin, regularly widened to apex antennae, form of pronotum with acute projected angles and sculpture of mesoventrite.
