Type material examined: Holotype : “TR [15] – Sinop, Çangal Dağı , Ordu, 30 km S Ayancık, 41°48'44"N, 34°39'19"E, 920 m, beech forest, 1.IV.2009, V. Assing GoogleMaps   / Holotypus  Cephennium victrix   sp. n., det. V. Assing 2020” (cAss). Paratypes: 1 , 2 : same data as holotype (cAss); 3 , 6 : “TR [16] – Sinop, Çangal Dağı, Ordu, 30 km S Ayancık, 41°47'50"N, 34°37'29"E, 360 m, sycamore forest, 1.IV.2009, V. Assing ” (cAss); 1 : “TR [20] – Sinop, 30 km SW Sinop, 41°58'03"N, 34°50'12"E, 65 m, mixed deciduous forest, 2.IV.2009, V. Assing” (cAss) GoogleMaps   .

Etymology: The specific epithet (Latin, adjective: winning) alludes to the shape of the median pair of internal structures of the aedeagus, which together form a “V” (as in victory).

Description: Body length 1.3–1.4 mm. Habitus as in Fig. 10 View Figs 9–16 . Colouration: body reddish to reddish-brown with the elytra often slightly paler than head and pronotum. Antennae with antennomeres VIII–X moderately transverse, other external characters as in C. varispinosum   .

: protibia subapically not curved, but somewhat flattened on inner side in apical portion; aedeagus ( Figs 40–41 View Figs 36–47 ) 0.33–0.35 mm long; ventral process subapically abruptly narrowed and apically acute in ventral view; internal sac with a pair of lateral clusters of small weakly sclerotized spines and with a median pair of longer weakly sclerotized spines forming a “V”; parameres thin, not sinuate, extending to apical fourth of ventral process.

Comparative notes: Cephennium victrix   is reliably distinguished from the similar C. varispinosum   especially by a smaller aedeagus with a ventral process and internal structures of different shapes and arrangement, respectively, additionally also by less transverse antennomeres VIII–X.

Distribution and natural history: The specimens were collected in three localities in Sinop province, North Turkey, by sifting leaf litter in a beech forest, in a moist sycamore forest with rocks, and in a mixed deciduous forest with hornbeam, oak, and laurel at altitudes of 65– 920 m.
