Afropselaphus muglanus nov.sp. ( Figs 4 , 8 , Map 1 )

T y p e m a t e r i a l: Holotype ♁: "TR - Muğla, No. 10, 20 km NNE Fethiye, N-exp. oakwood, 970 m, 36°47'28N, 29°11'29E 27.III.2002, V. Assing / Afropselaphus muglanus spec. nov. ♁ det. Brachat 2021 / Holotypus " (cBra). Paratypes: 2♁♁ [1 without aedeagus], 2♀♀: same data as holotype (cBra).

E t y m o l o g y: The specific epithet is an adjective derived from Muğla, the name of the Turkish province where the species was discovered.

D e s c r i p t i o n: Body length 1.80-1.90 mm. Other measurements (in mm): HL: 0.36-0.38; HW: 0.27-0.28; AL: 0.94-1.00; PpL: 0.40 mm; PL: 0.32-0.34; PW: 0.29-0.30; EL: 0.40-0.42; EW: 0.64-0.68; AedL: 0.40. Habitus as in Fig. 4 .

Eyes composed of 7-8 ommatidia. Antennae with all antennomeres distinctly oblong. Apical club of maxillary palpomere IV 0.22 mm long. Pronotum weakly oblong and slightly broader than head, with distinct ante-basal lateral foveae connected to basal margin of pronotum by fine keel; median ante-basal fovea obsolete. Elytra broadest at posterior margins.

♁: metaventrite more strongly convex than in female; sternite IV with narrow medio-basal impression extending beyond middle of sternite; aedeagus ( Fig. 8 ) with convex apex bent ventrad; internal sac with a broad sclerite of triangular shape and with numerous minute denticles.

C o m p a r a t i v e n o t e s: This species is distinguished from the geographically close A. pisidicus (see below) by a longer, more slender, and apically more strongly tapering aedeagus with longer parameres and with internal structures of different shapes.

D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The type specimens were sifted from litter in an oak forest near Fethiye (Southwest Turkey: Muğla) ( Map 1 ) at an altitude of 970 m.
