Description
Animal limaciform, subcylindrical, blunt behind, with a but little developed mucous pore; mantle anterior, close to the head, concealing a shell-plate; a distinct locomotive disk; respiratory orifice on the right anterior margin of the mantle; genital orifice behind and below the right eye-peduncle. Shell-plate calcareous, ovate, small and solid. Jaw costulated; lingual dentition as in Arion.[5]
The main diagnostic feature of the reproductive system differing from genera Arion, Letourneuxia and Ariunculus is, that species in the genus Geomalacus has atrium with diverticulum.[6] The free oviduct is short; the retractor muscle is attached to the spermatheca duct; vas deferens and epiphalus are long.[6]
