Deroceras (Deroceras) libanoticum (Pollonera, 1909)
Deroceras libanoticum is only known from Pollonera's original description and might be synonymized with D. bertyensis in the future (Wiktor 2000).
External: Brown-black body (Wiktor 2000); pale sole (Wiktor 2000).
Internal: Penis with a deep longitundinal medial constriction, with the apical half slightly smaller than the basal half; penial gland a single, cylindrical, curved structure without papillae; vas deferens probably attached to side; retractor muscle unbranched, attached on apical side of penis near medial contriction; large, ovate spermatheca with a narrow duct; spermatheca slightly longer than penis; probably no rectal caecum (Wiktor 2000).
Similar to D. bertyensis externally but smaller (Heller 2009).
22-25 mm long (Heller 2009).
Only on Mt. Hermon, Israel (Heller 2009).
