Cephennium (Macroderus) malagae nov.sp. ( Figs 20 , 70-71 , 78 , Map 3 )

Type material: Holotype ♂: "E. Andalusien (MA), Sierra de Bermeja, 350-1450 m, 26.III.1994 Assing / Holotypus ♂ Cephennium malagae sp. n. det. V. Assing 2020" ( cAss) . Paratypes: 3♂♂, 3♀♀: same data as holotype (cAss) ; 2 exs.: "E– Andalusia, MA Sierra Bermeja, Puerto de Penas blancas 1200 m, 26.3.94 Wunderle leg." (cAss) ; 1♂, 2♀♀: "E Andalusien, Sierra Bermeja, Meybohm 18.2.2000 / N36°29' W5°12 ', Nordhang Pinsapow." (cAss) ; 1♂, 1♀: "E. Andalusien (MA), Sierra de Palmitera , SO Ronda, 900 m, 24.III.1994 Assing 13" (cAss) .

Etymology: The specific epithet is the genitive of Malaga, the name of the region where this species was collected.

Description: Body length 1.3-1.5 mm. Body ( Fig. 20 ) very broad. Colouration reddish to reddish-brown. Eyes composed of seven ommatidia. Pronotum approximately 1.3 times as broad as long. Elytra with anterior sulci short, approximately as long as the combined length of the basal three antennomeres. Other external characters as in C. alacantae .

♂: metaventrite shallowly impressed; aedeagus ( Figs 70-71 ) large, 0.43-0.45 mm long; ventral process of quadrangular shape, in the middle weakly projecting; internal structures as in Fig. 78 ; parameres apically reaching apex of median lobe (or very nearly so).

Comparative notes: Cephennium malagae differs from other representatives of Macroderus by a significantly larger aedeagus with a ventral process of quadrangular shape and much smaller and differently shaped internal structures.

C o m m e n t: Besuchet (unpubl.) examined material from various localities near Ronda and in the Rif mountains (North Morocco), which he assumed to belong to the same species (working name: C. kuehnelti i.l.). Based on his drawings of the aedeagus, at least the specimens from the environs of Ronda may belong to C. malagae . Considering the restricted distributions of the Spanish Macroderus species, however, it appears rather unlikely that the material from Morocco should belong to C. malagae , too.

Distribution and natural history: The species was found in Sierra Bermeja and Sierra de Palmitera (a mountain in the Serrania de Ronda range), Malaga (South Spain: Andalucía) ( Map 3 ). The specimens with labels specifying exact altitudes were collected at 900 and 1200 m, three of them in an Abies pinsapo forest.
