( Figs 2 , 19 ) Type material: Holotype ♂ : " GR-Makedonia , Umg. Litóhoro , Mt. Olimbos , O-Seite ca. 500 m , 19.5.87 , leg. Brachat / Holotypus ♂ Cephennium olympicum sp. n. det. V. Assing 2020" ( cAss ) . Paratypes : 1♂ , 1♀ : same data as holotype ( cAss ). Etymology: The specific epithet is an adjective derived from Olympos, the name of the mountain where the type locality is situated. Description: Body length 1.3-1.4 mm ; antenna approximately 0.75 mm long. Colouration: head and pronotum reddish-brown; elytra blackish-brown. Habitus ( Fig. 2 ), size, and other external characters as in C. dilatatum , except as follows: Antennae more slender; antennomeres IX and X barely 1.5 times as broad as long. Pronotum with very indistinct median elevation posteriorly. ♂ : protibia subapically strongly excavate, only very weakly curved, and apically distinctly dilated; aedeagus ( Fig. 19 ) 0.37-0.38 mm long; median lobe apically acute; internal structures rather massive, rather strongly sclerotized, and of distinctive shapes; parameres slender, not reaching apex of median lobe, with rather long apical seta. Comparative notes: Like C. dilatatum , C. olympicum belongs to the C. perispinctum group. It differs from other representatives of this group particularly by the modifications of the male protibiae and by the structure of the aedeagus. From C. assingi , with which it shares a similar shape of the aedeagus, it differs in the internal structures of the aedeagus and by the modifications of the male protibiae. Distribution and natural history: Thetypelocalityissituated in eastern slopes of Oros Olympos at an altitude of approximately 500 m .
