Material examined.

Burdur • TR 11-2024 , Söbüce , first order stream, 37.287872°N, 30.067743°E, 24 Apr. 2024, leg. Pešić, Zawal, Gülle & Gülle, 1 ♀ (sequenced), dissected and slide mounted ( RMNH) GoogleMaps .

Remarks.

The female from Burdur used in this study for molecular analysis, matches the description of A. subasper , a species easily identified by a pointed and protruding gnathosomal rostrum, three pairs of acetabula arranged in a weakly curved line and a rather homomorphic S- 1 and S- 2 setae on I-L- 5 (see Gerecke 2003). The specimen from Türkiye forms a unique BIN (BOLD: AGG 3778) with the nearest neighboring BIN being BOLD: AEX 4044, which includes specimens from Serbia, Italy, Bulgaria, Albania, and Switzerland. The p - distance between these two BINs is estimated at 8.67 %. The only public sequence in BOLD: AEX 4044 belongs to a female specimen from Serbia morphologically assigned by Jovanović et al. (2024) to A. glandulosus (Walter, 1918) , a species with certainty known from the Alps, southern Germany, and the Pyrenees ( Gerecke 2003). Re-examination of the female from Serbia revealed good agreement with A. subasper , except in the shape of the gnathosoma, which is with a short rostrum, not pointed and protruding as in typical subasper specimens. The results of the applied ASAP procedure grouped the sequences of these two BINS into the same MOTU (hypothetical species). The BIN BOLD: AES 6460 which groups the sequence of A. subasper from Sardinia forms a separate MOTU with a high genetic distance (10.91 % p - distance) to the next closest BIN of A. subasper (BOLD: AEX 4044) indicating that the populations from Sardinia probably represent a species new to science.
