Schülke [GR2019-18b]" ( MNB) ; 1♀: " GREECE, NNW Drama, Oros Falakró, Umg. Skistation , Schneefeldrand , Gesiebe , 41°16'17''N, 24°04'15''E, 1720- 1750 m, 7.V.2019, leg. M.

Etymology: The specific epithet is an adjective derived from Drama, the region where the species was collected.

Description: Body length 1.2-1.3 mm; antenna 0.6 mm long. Habitus ( Fig. 8 ) rather slender. Body reddish to reddish-brown.

Eyes composed of approximately eight ommatidia. Antenna with antennomeres V and VII longer and more oblong than antennomeres VI and VIII; antennomeres X approximately 1.5 times as broad as long and XI approximately 1.5 times as long as broad.

Pronotum approximately 1.15 times as broad as long, moderately convex in crosssection; punctation very fine to moderately fine, less distinct than that of elytra.

Elytra broader than pronotum, moderately convex in cross-section, anteriorly each with a small transversely oval impression with tomentose whitish pubescence; punctation moderately fine and distinct.

♂: protibia apically very strongly excavate and curved; meso- and metatibia apically flattened and somewhat excavate, but not distinctly curved; metaventrite extensively depressed or indistinctly impressed; aedeagus ( Figs 30-33 ) 0.33-0.36 mm long; median lobe apically acute both in ventral and in lateral view; internal structure narrowly clip-shaped; parameres slender, weakly curved, not reaching apex of median lobe, and apically with rather long seta.

Comparative notes: Cephennium dramanum is distinguished from other species of slender habitus and reddish colouration particularly by the modifications of the male tibiae and by the structure of the aedeagus.

Distribution and natural history: The type specimens were found in Oros Falakro and a locality to the east of this mountain in the Dráma region, Northeast Greece. Those collected by Michael Schülke were sifted from debris near snow. The altitudes range from 1100 to approximately 1750 m.
