Cephennium algarvense nov.sp. ( Figs 4 , 38-40 , Map 1 )

Type material: Holotype ♂: " P Algarve, 530 m, Serra Monchique , ö Monchique, Meybohm 10.4.2002, N37°19', W8°31' / Holotypus ♂ Cephennium algarvense sp. n. det. V. Assing 2020" ( cAss) . Paratypes: 3♂♂, 5♀♀: same data as holotype (cAss) ; 8♂♂, 1♀: "P Algarve, 550 m, Serra Monchique , w Monchique, Meybohm 15.4.2002, N37°18', W8°33'" (cAss) ; 6♂♂, 2♀♀: " Portugal Algarve , Serra de Monchique , Umg. Portela Viuva, Meybohm 20.2.1999 " (cAss) ; 2♂♂: same data, but 21.2.1999 (cAss) ; 5♂♂, 2♀♀: " Portugal Algarve , Serra de Monchique , nördl. Foia 800 m, Meybohm 19.2.1999 " (cAss) ; 14♂♂, 6♀♀: " Portugal Algarve , Serra de Monchique , nordwestl. Picota, Meybohm 23.2.1999 " (cAss) .

Etymology: The specific epithet (adjective) alludes to the currently known distribution, which is confined to Algarve.

Description: Small species; body length 0.9-1.0 mm. Habitus as in Fig. 4 . Head and pronotum pale-reddish to dark-reddish; elytra brown, rarely of similar colouration as head and pronotum. External and male secondary sexual characters as in C. validum ; distinguished only by the morphology of the aedeagus.

♂: aedeagus ( Figs 38-40 ) 0.20-0.22 mm long; median lobe apically nearly truncate, in the middle weakly produced; internal structures small and indistinct; parameres stout, straight, apically nearly reaching apex of median lobe, and with moderately long apical seta.

Comparative notes: This species is distinguished from other representatives of the C. validum group only by the shape of the smaller aedeagus.

Distribution and natural history: The currently known distribution is confined to Sierra de Monchique, Algarve, South Portugal ( Map 1 ). The specimens collected in 2002 were sifted from litter of Rubus and near an abandoned house.
