Present material is difficult to allocate since it shows a mixture of characters of L. bannwarthi Schellenberg, 1928 and L. gracilis . The gnathopod 2 has the posterior margin bare and the carpus tapered while the telson is less than 1.8 × its width. All these are features of L. bannwarthi . On the other hand, the dactylus of gnathopod 2 reaches over half the length of the propodus, coxa 4 is serrate on anterior and distal margins and telson is distally tridentate, all features of L. gracilis . For the present, due to the serrate coxa 4, this material is allocated to L. gracilis . This would be the first record of L. gracilis from the Indian Ocean. Habitat. Dead coral heads in shallow water. Distribution. Australia , Chagos.
