This study reports the first record of two brachyuran crab species, Austruca albimana Kossmann, [21] and Tirmilyra concinnus Ghani and Tirmizi [18], from the western Indian coast. Their identification, taxonomic observations, and geographic distribution are provided. The species belong to the families Ocypodidae and Leucosiidae, respectively. This is the first report from Indian waters, as the species are so far reported from Oman, Iran and Persian Gulf. These records emphasize the need for research and conservation efforts in the region to explore the diversity and distribution of brachyuran crabs in Indian waters.

Synidotea variegata (Collinge, 1917) is associated with the sea urchin Stomopneustes variolaris (Lamarck, 1816), where it is frequently found inhabiting the spaces among the spines, and around the peristomial region. Previously, this species was known only from the southwestern coast of India. This study reports the presence of the isopod S. variegata in the Gulf of Kutch, Gujarat, northwestern coast of India.
