( Figs 109–110 )

Type material: Holotype ♂: “ N35°23'54 E23°54'38, GR Westkreta 440 m, Karanos W 31.3.2019, Brachat & Meybohm (14) / Holotypus ♂ Cephennium meybohmi sp. n. det. V. Assing 2019” ( cAss).

Etymology: This species is dedicated to Heinrich Meybohm, specialist of Scydmaeninae , who discovered the holotype and granted permission to retain it.

Description: Body length 0.95 mm; width of pronotum 0.38 mm; width of elytra 0.40 mm. Coloration: body pale-reddish; legs, antennae, and maxillary palpi yellow. Eyes reduced, composed of three ommatidia without pigmentation. Punctation of head and elytra extremely fine, barely noticeable at a magnification of 150 x, that of pronotum visible, but very fine in anterior three-fourths, more distinct only in posterior fourth. Tibiae moderately club-shaped, dilated in distal three-fifths. Other external characters as in C. selinonum .

♂: aedeagus 0.24 mm long; ventral process apically convex in ventral view, distinctly curved and acute in lateral view; internal sac with two pairs of large sclerotized spines and with numerous additional smaller spines ( Figs 109–110 ).

Comparative notes: Cephennium meybohmi is reliably distinguished from other species of the C. arcuatum group by the shape and internal structures of the aedeagus. It differs from C. selinonum , the geographically closest congener of the C. arcuatum group, by less distinct punctation in the anterior three-fourths of the pronotum, the shape of the larger aedeagus in lateral view, and particularly by the presence of numerous smaller spines in the internal sac of the aedeagus.

Distribution and natural history: The type locality is situated near Karanos to the southwest of Chania. The holotype was collected by washing soil from a stream valley with Platanus orientalis at an altitude of 440 m.
