Meybohm / Holotypus  Cephennium sicaferum sp. n., det. V. Assing 2020” (cAss). Paratype : “ N37°56'47 E027°53'53 (8), Türkei Aydin Pasayaylasi, 1460 m 20.4.2006, l. Brachat & Meybohm” (cAss) .

Etymology: The specific epithet is an adjective composed of the Latin noun sica (dagger) and the suffix -ferum (carrying). It alludes to the presence of a pair of daggershaped structures in addition to a pair of claw-shaped structures in the internal sac of the aedeagus.

Description: Body length 0.9 mm. Eye rudiments minute, composed of three distinct ommatidia without pigmentation. Other external and male secondary sexual characters as in C. unguicum .

: aedeagus ( Fig. 61 ) of similar shape as in C. unguicum , but smaller, 0.18 mm long; internal sac with a pair of large and strongly curved claw-shaped structures and additionally with a pair of dagger-shaped structures.

Comparative notes: Cephennium sicaferum is distinguished from the geographically close C. unguicum by slightly smaller body size, eye rudiments composed of three distinct ommatidia, and by a smaller aedeagus with a pair of dagger-shaped structures in addition to a pair of smaller and differently shaped claw-shaped structures. The species differs from the externally similar C. deplectens (see below) only by the longer and more slender dagger-shaped structures and the differently shaped claw-shaped structures in the internal sac.

Distribution and natural history: The type locality is situated near Paşayaylası, Aydın province, Southwest Anatolia ( Map 3 ). The holotype was sifted from litter on a stream bank with Salix and Rubus at an altitude of 250 m, the paratype was found under stones or sifted near stones near a stand of walnut trees at an altude of 1460 m.
