Type material: Holotype : “ N37°23'45 E036°48'05, TR Kahramanmaras, Uzunsögut 660 m (47), 30 km ssw K. Maras / Laubstreu, 4.5.2005, leg. Brachat & Meybohm / Holotypus  Cephennium marasicum sp. n., det. V. Assing 2020” (cAss) . Paratypes: 1 , 1 : “ N37°26'04 E036°44'32 (8), TR Kahramanmaras, 25 km sw Maras, Yesilyöre 800 m, Brachat & Meybohm 23.4.2007 ” (cAss) .

Etymology: The specific epithet is an adjective derived from Maras, alluding to the fact that the type locality is situated in the Turkish province Kahramanmaraş.

Description: Habitus as in Fig. 15 . Punctation of pronotum more distinct than that of elytra. Other external and male secondary sexual characters as in C. corruptum .

: aedeagus ( Fig. 52 ) short, broad, and apically truncate, 0.33 mm long; internal sac with structures of distinctive shape; paramere apically extending beyong apex of median lobe, with short apical seta.

Comparative notes: Cephennium marasicum is distinguished from the externally similar and geographically close C. corruptum only by relatively more distinct punctation of the pronotum, as well as by the internal structures and longer parameres of the larger aedeagus.

Distribution and natural history: This species is currently known from only two localities to the southwest of Kahramanmaraş, Kahramanmaraş province, central southern Anatolia ( Map 3 ). The specimens were sifted from leaf litter near rocks at altitudes of 660 and 800 m.
