Paratypes: 3 , 1 : same data as holotype (cAss); 2 : “ N37°33'28 E36°25'54, TR Kahramanmaras, Torlar 1110 m (41), 18 km sö Andirin / Streu , Steine (41), 30.4./ 2.5.2005 (45), leg.

Brachat & Meybohm” (cAss); 1 : “ N37°39'14 E36°26'27, TR Kahramanmaras, Andirin 12,5 km NE, S Geben, 1500 m, Brachat & Meybohm, 27.4.2007 ” (cAss) .

Etymology: The specific epithet (without a fringe) alludes to the absence of fimbriate structures in the internal sac of the aedeagus.

Description: Habitus as in Fig. 19 . Punctation of pronotum not more distinct than that of elytra. Other external and male secondary sexual characters as in C. marasicum and C. corruptum .

: aedeagus ( Fig. 55 ) short, broad, and apically truncate, approximately 0.27 mm long; internal sac with non-fimbriate structures of distinctive shapes; paramere apically extending slightly beyond apex of median lobe, with short apical seta.

Comparative notes: Cephennium affimbriatum is reliably distinguished from other species of the C. corruptum group only by the shape and internal structures of the aedeagus.

Distribution and natural history: The currently known distribution is confined to the environs of Andırın in the west of Kahramanmaraş province, central southern Anatolia ( Map 3 ). The specimens were sifted from litter of fir, hornbeam, cedar, and other plants, partly between rocks, at altitudes of 1110–1500 m.
