Abstract

The land snail genus Eobania P. Hesse, 1913 in Croatia consists of four taxons. The mean shell largest diameters (D) of the 13 samples ranged from 19,99 mm to 31,78 mm and the mean shell height (H) from 17,31 mm to 25,66 mm. The shell morphology confirms that all islands populations are smaller with examples of nanism on outside islands Palagruža and Sušac. Molecular analysis (16S rDNA and COI sequence data) showed no significant differences between the South – Adriatic population from the mainland and islands, thus providing no molecular–genetic evidences for classification of a single E. vermiculata species into separate subspecies. The observed differences could, probably, be attributed to ecological influences.The mean size of the largest population was approximately 1,5x larger than the mean size of the smallest population. The low variance between the size variation within populations and variation in shell shape were not expected
