Description of the genitalia.
Two specimens were anatomically examined. Penis slim, with the retractor muscle attached at its distal end; penial caecum very small, vestigial, consisting of two
"tubercles"
; epiphallus very long and cylindrical; there is clear distinction between the vas deferens and the epiphallus; vas deferens long and relatively thick; a slender retractor muscle is attached near the proximal end. Vagina short and thick, but pedunculus relatively long; bursa copulatrix extremely long, with
the
distal end slightly expanded. In one specimen an elongated, simple spermatophore was found with the apical portion slightly thickened.
Distribution.
Orcula (Illyriobanatica) jetschini
is known only from western part of Romania (Banat,
Crisana
and Western Transylvania). The Hungarian record (
Pinter
and Suara 2004
) is apparently based on a flotsam specimen so its origin is suspect (
Varga, 2009
).
Negrea (1966)
reported the species from Moldova
Nouă
, which lies close the Serbian border and, therefore, it is expected to occur in Serbia. The Pleistocene distribution of
Orcula dolium
included the
''Pozarevac
Danube
Area''
(
Mitrovic
2007
), which is just on the other bank of the Danube River, but temporal and spatial sympatry of
Orcula (Illyriobanatica) jetschini
and
Orcula (Orcula) dolium
is not verified.
Ecology.
The species inhabits deciduous forests. It is found most commonly between small stones and leaf litter on the forest floor or under hazelnut (
Corylus
) bushes. The species is known from non-limestone bedrock, such as the Zarand Mountains.
Conservation status.
Least concern (LC) according to IUCN criteria (
Feher
2011
).
Remarks.
All living specimens found were covered in mud, causing them to appear like tiny grains of soil. The ribbed shell is possibly an adaptation for camouflaging. The photographs herein are of cleaned shells.
