A new deep-sea munidopsid squat lobster of the genus Leiogalathea Baba, 1969 (Decapoda: Anomura) from the southeastern Arabian Sea, India

The present study describes a new species of the deep-water munidopsid squat lobster genus Leiogalathea Baba, 1969. Leiogalathea samudragiri sp. nov. resembles L. achates Rodríguez-Flores, Macpherson & Machordom, 2019, L. evander Rodríguez-Flores, Macpherson & Machordom, 2019, and L. laevirostris (Balss, 1913) by the unarmed hepatic margin of the carapace. However, the new species differs from these congeners mainly in having uninterrupted mesogastric and mid-transverse ridges on the carapace and the presence of six transverse ridges on the posterior half of the carapace.
