Cephennium brachati nov.sp. ( Figs 4 , 23 , 39 )

Type material: Holotype ♂: " GR-Makedonia, Bez.: Florina, Umgeb. Pass Florina/Pissoderi , ca. 1400 m, 19.5.94, leg. Brachat / Holotypus ♂ Cephennium brachati sp. n. det. V. Assing 2020" ( cAss).

Etymology: This species is dedicated to our friend Volker Brachat (Geretsried), who collected the type material of not only of this, but also of several other species described in the present paper.

Description: Body length 1.3 mm; antenna 0.6 mm long. Colouration: head and pronotum dark reddish-brown; elytra blackish-brown. Habitus ( Fig. 4 ) and other external characters as in C. dilatatum , except as follows:

Pronotum without median elevation posteriorly.

♂: protibia apically distinctly bent and weakly excavate; aedeagus ( Figs 23 , 39 ) very large, 0.45 mm long; median lobe apically acute in the middle; internal structures weakly sclerotized, lateral structures connected by a circular structure; parameres slender, not reaching apex of median lobe, with moderately long apical seta.

Comparative notes: This species is distinguished from other representatives of the C. perispinctum group particularly by the size, shape, and internal structures of the aedeagus.

Distribution and natural history: The type locality is situated in Flórina, Northwest Greece, at an altitude of 1400 m. Other data are not available.
