Última Redefinition of Thapsia Albers, 1860, and description of three more helicarionoid genera from western Africa (Gastropoda, Stylommatophora) Naturalis Winter, A.J. de. As presently used, the helicarionoid genus Thapsia Albers, 1860 embraces a large, heterogeneous assemblage of species. As a first step in the revision of this group of taxa, the genus Thapsia (type species Helix troglodytes Morelet, 1848) is redefined anatomically and conchologically. In the absence of alcohol-preserved material of T. troglodytes, Thapsia ebimimbangana spec. nov. from Cameroon and T. wieringai spec. nov. from Gabon are described to characterize the soft parts morphology of Thapsia. Three new genera are introduced, viz. Saphtia gen. nov. (type species S. granulosa spec. nov.), Pseudosaphtia gen. nov. (type species P. brunnea spec. nov.) and Vanmolia gen. nov.

Ano: 2008 URL: http://www.repository.naturalis.nl/record/273964 Two new Semi-slugs from Gambon, Western Afreca (Gastropoda: Pulmonata: Urocyclidae) Naturalis Winter, A.J. de. Zonitarion dewildei spec. nov. and Z. wakaensis spec. nov., both belonging to the subgenus Belonarion, are described from the rain-forest area of Gabon, western Africa. This is the first record of urocyclid semi-slugs from this malacologically poorly known area. Descriptions are provided of both external and internal organs, viz., jaw, radula, genital system, pallial organs and spermatophore.
