Description of a new limacid slug in Menorca (Balearic Islands, Spain) Gigantomilax (Vitrinoides) benjaminusn. sp. (Gastropoda, Pulmonata)We describe a new endemic limacid slug, Gigantomilax (Vitrinoides)benjaminus n. sp. and we compare it with the nearest species, particularly with Gigantomilax (V.)majoricensis, another Balearic endemism. Characteristic features of this new species include its small size, translucid and smooth body, and totally grey dorsum with no bands or spots. The reproductive system shows a well developed vas deferens surrounded by the distal part of prostatic gland, a thin penial retractor muscle, swollen prostate and small distal genitalia. The recent redescription of Limax majoricensis by Wiktoret al. (2007) is discussed and we consider that these authors refer to G. benjaminus n. sp., and so we dessign the neotype of Gigantomilax (V.) majoricensis.
