Afropselaphus tenuispinosus nov.sp. ( Fig. 13 , Map 1 )

T y p e m a t e r i a l: Holotype ♁: " N37°12'30 E31°12'31 (5) TR Antalya, Köprü-Tal n Beşkonak , ca 500 m 13.IV.2008 leg. Meybohm & Brachat / Afropselaphus tenuispinosus spec. nov. ♁ det. Brachat 2021 / Holotypus " (cBra) . Paratypes: 6♁♁, 4♀♀: same data as holotype (cBra) ; 1♁: "TR-Südküste Umgeb. Antalya Selge ; 900 m; 22.5.2000 Meybohm & Brachat" (cBra) .

E t y m o l o g y: The specific epithet (Latin, adjective) alludes to the slender internal structure of the aedeagus.

D e s c r i p t i o n: Body length 1.65-1.80 mm. Other measurements (in mm): HL: 0.34-0.37; HW: 0.24-0.27; AL: 0.80-0.88; PpL: 0.32-0.34 mm; PL: 0.30-0.32; PW: 0.26- 0.28; EL: 0.36-0.38; EW: 0.60-0.63; AedL: 0.34-0.36.

Eyes composed of 6-7 ommatidia. Antennae slender; all antennomeres longer than broad. Apical club of maxillary palpomere IV slightly more than half as long as total length of palpomere IV. Pronotum weakly oblong and slightly broader than head, with distinct median ante-basal fovea. Elytra broadest anterior to posterior margin.

♁: metaventrite more distinctly convex than in female; sternite IV without medio-basal impression; aedeagus ( Fig. 13 ) apically curved ventrad; internal sac with long and slender spine.

C o m p a r a t i v e n o t e s: The shape of the internal spine of the aedeagus is most similar to that of A. wolfi , from which A. tenuispinosus differs by the presence of a median ante-basal fovea on the pronotum, the absence of a medio-basal impression on the male sternite IV, and a longer internal spine of the aedeagus.

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: This species was discovered in two close localities some 54-60 km to the northeast of Antalya, Antalya province, South Turkey ( Map 1 ). The specimens were sifted from litter between rocks at altitudes of 500 and 900 m.
