Material.

Albania, Bjeshkët e Nemuna (Prokletije Mts), above village Okol, near pass Qafa e Pejës, W slope of Mt. Maja e Popluks, at a spring on limestone, 1660 m, 42°27.343'N, 19°46.478'E, leg. Barina, Z., Puskás, G., Sárospataki, B., 16.07.2010., HNHM 98841.

Description of the genitalia.

One specimen was dissected. Penis cylindrical and slim, with a short, but thick penial caecum, the proximal portion broader than the short and slimmer distal portion; retractor muscle attaches at the penis–epiphallus transition; epiphallus more than twice as long as the penis and much thicker, its transition to the vas deferens is gradual, barely discernable; there is a slim retractor muscle attached to the proximal portion of the epiphallus; proxim\al portion of the vas deferens thicker than the distal part. Vagina and free pedunculus extremely short; bursa copulatrix almost twice as long as the combined length of the penis–epiphallus complex.

Conservation status.

Orcula (Orcula) wagneri is listed as Near Threatened (NT), being close to the criteria threshold for Vulnerable ( Pall-Gergely 2011a).

Remarks.

Our observations on the genitalia agree with that of Schileyko (2012), who investigated the anatomy of Orcula wagneri from the Tomor Mountains ( ‘’ Maja e Tomorit Mt., S Albania’’). A partially reabsorbed, elongated, spermatophore was located in the bursa copulatrix (Fig. 8B).
