Cephennium (Macroderus) cujonicum nov.sp. ( Figs 15 , 23 , 65 , Map 3 )

Type material: Holotype ♂: "E - Castilla-La Mancha, Sierra de Segura , Sierra de Cujón , 1460 m, [2], 38°28'03N 02°20'38W, 15.III.2008, V. Assing / Holotypus ♂ Cephennium cujonicum sp. n. det. V. Assing 2020" ( cAss) . Paratype ♂: same data as holotype ( cAss).

Etymology: The specific epithet is an adjective derived from Cujón, the mountain where the species was discovered.

Description: Body length 1.3 mm. Habitus as in Fig. 15 . Colouration yellowishred. Pubescence of pronotum and elytra moderately long and depressed. Eyes composed of approximately five ommatidia. Pronotum 1.3 times as broad as long. Elytra with anterior sulci approximately as long as the combined length of the basal four to five antennomeres. Other external characters as in C. alacantae .

♂: metaventrite depressed, not distinctly impressed; aedeagus ( Fig. 65 ) 0.32 mm long; apex of median lobe broadly obtuse in ventral view; internal structures large and distinctive; parameres apically nearly reaching apex of median lobe.

Comparative notes: Cephennium cujonicum differs from C. alacantae by smaller size, paler colouration, a less robust body, a less transverse pronotum, a depressed (not impressed) male metaventrite, and by the shape and internal structures of the smaller aedeagus.

Distribution and natural history: Thetypelocalityissituated in Sierra de Cujón, a mountain in the Sierra de Segura range ( Map 3 ). The specimens were sifted from grass and moss near large calcareous rocks at an altitude of 1460 m ( Fig. 23 ).
