( Figs 18 , 54 , Map 3 )

Type material: Holotype : “TR Karahmanmaras [sic] (18) Pass N Tekir S Göksun, 1400–1550 m / 37°56'56N 36°34'E (18) 26.4.2004, Brachat & Meybohm / Holotypus  Cephennium besucheti sp. n., det. V. Assing 2020” (cAss) . Paratypes: 2 , 3 : same data as holotype (cAss).

Etymology: This species is dedicated to our late friend, Claude Besuchet, specialist of Pselaphinae and Scydmaeninae . He studied Cephennium , including the available type material of the described species, in the 1960s, prepared superb drawings of the aedeagus of both described and numerous undescribed species, but unfortunately never published his results. He also participated in the field trip to Turkey in 2004.

Description: Habitus as in Fig. 18 . Pronotum with more distinct punctation than elytra. Other external and male secondary sexual characters as in C. marasicum and C. corruptum .

: aedeagus ( Fig. 54 ) short, broad, and apically truncate, approximately 0.33 mm long; internal sac with narrowly fimbriate structures of distinctive shape; paramere apically extending slightly beyond apex of median lobe, with short apical seta.

Comparative notes: Cephennium besucheti 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 type locality is situated to the southeast of Göksun in the west of Kahramanmaraş province, central southern Anatolia ( Map 3 ). The specimens were sifted from litter on slopes with cedar, fir, and cypress at an altitude between 1400–1550 m.
