New species and records of terrestrial slugs from East Africa (Gastropoda, Urocyclidae, Veronicellidae, Agriolimacidae).

New and little-known terrestrial slugs are dealt with based on extensive collections made in East Africa (Kenya, Tanzania, and Uganda) 1993-2007. This account deals primarily with larger species from forests in the Eastern Arc Mountains of Tanzania. In Veronicellidae, Germain, 1908 is extended to Tanzania by P. (Hoffmannia) zootoca tanzaniensis in the Udzungwa Mts. In Urocyclidae, is described from the Pare Mts. and is described from the Uluguru Mts. In Urocyclinae, is described from the Usambara Mts., from the Uluguru Mts., and from the Udzungwa Mts. In addition, the ill-defined genus Simroth, 1910 is discussed and the little-known Pollonera, 1906 is reported from Uganda. In Agriolimacidae, a species of Rafinesque, 1820 is reported for the first time from southern Tanzania. The taxonomic attribution and significance of each discovery is discussed.
