Wunderle / Holotypus  Cephennium nemruticum sp. n. , det. V . Assing 2020” (cAss). Etymology : The specific epithet is an adjective derived from Nemrut, the name of the mountain where the species was discovered. Description : Body length 1.2 mm . Habitus as in Fig. 21 . Punctation of pronotum only slightly more distinct than that of elytra. Eye rudiments very small, composed of approximately 3 weakly defined ommatidia. Other external and male secondary sexual characters as in C. marasicum and C. corruptum . : aedeagus ( Fig. 51 ) short, broad, and apically truncate, approximately 0.33 mm long; internal sac with weakly sclerotized non-fimbriate structures of distinctive shapes; paramere apically extending to apex of median lobe, with short apical seta. Comparative notes : Cephennium nemruticum is reliably distinguished from other species of the C. corruptum group only by the shape and internal structures of the aedeagus.

The holotype was sifted from leaf litter in a rocky slope with oak at an alitude of 870 m .
