urn:lsid:zoobank.org:act:7321FC90-18ED-4F50-8CFA-58F338EA62BB

Type material examined: Holotype : “ N41°28'08 E32°35'52 (21), TR Bartin 30.4.2014, Bahcedik 3 km s 510 m, Brachat & Meybohm / Holotypus  Cephennium spinigerum sp. n., det. V. Assing 2020” (cAss).

Etymology: The specific epithet (Latin, adjective: spinose) alludes to the numerous spines in the internal sac of the aedeagus.

Description: Body length 1.4 mm. Habitus as in Fig. 11 . Colouration: body dark-reddish. 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 42–43 ) 0.38 mm long; ventral process apically of triangular shape in ventral view; internal sac with numerous rather stout spines; parameres thin, not sinuate, extending to apical third of ventral process.

Comparative notes: This species is distinguished from the similar and geographically close C. victrix only by the shape and internal structures of the aedeagus.

Distribution and natural history: The type locality is situated in Bartin province, Northwest Anatolia ( Map 2 ). The holotype was sifted from litter near old trees in a beech forest with rhododendron undergrowth at an altitude of 510 m.
