Type material: Holotype ♂: "E. Andalusien (GR), Sierra Nevada, Solynieve, 1700- 1900 m, 21.III.1994 Assing 6 / Holotypus ♂ Cephennium nevadae sp. n. det. V. Assing 2020" (cAss) . Paratypes: 3♂♂: same data as holotype (cAss); 2 exs.: "E Andalusia GR Sierra Nevada Str. zur 1700 m, N-Hang, Pinus Junip., 21.03.94 Wunderle leg." (cAss) .

Etymology: The specific epithet is the genitive of Nevada, the name of the mountain range where the type locality is situated.

Description: Body length 1.4-1.5 mm. Habitus as in Fig. 18. Colouration palereddish. Eyes composed of approximately seven ommatidia. Elytra with anterior sulci approximately as long as the combined length of the basal four to five antennomeres. Other external characters not distinctive.

Comparative notes: Cephennium nevadae is distinguished from other Macroderus species only by the shape and internal structures of the aedeagus.

Distribution and natural history: The type material was found below Sol y Nieve (= Pradollano), Sierra Nevada, Andalucía (Map 3). The specimens were sifted from litter and debris, partly near snow, in a stream valley at an altitude of 1900 m.
