Original Article


Two new species of Ligia are described, L. persica sp. nov. from the Persian Gulf and L. yemenica sp. nov. from the Gulf of Aden. Ligia persica occurs along the northern coasts of the Persian Gulf and around some Iranian islands such as Qeshm and Kish. A comparison of SEM micrographs shows that the shape and ornamentation of distal parts of the appendix masculina are reliable characters for the identification of morphologically similar Ligia species. They are species-specific and of great importance in the taxonomy of the genus.
