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).
