Abstract

The woodlouse species Tylosmaindroni Giordani Soika, 1954 (Crustacea, Isopoda, Oniscidea) is redescribed from the Persian Gulf based on light and scanning electron microscopy. This species differs from the closely related T.exiguus Stebbing, 1910, from the Red Sea (coasts of Sudan and Eritrea), and Socotra Island, by pereopod 1 superior margin without a prominent projection and pleopod 2 endopod 2.3 times as long as exopod, vs. 3.6 in T.exiguus. A distribution map for T.maindroni is provided. In addition, we studied the molecular differentiation of five populations of T.maindroni from the Persian Gulf, based on partial cytochrome c oxidase subunit I (COI) gene sequences. The results revealed low levels of population structuring between the analyzed populations.
