Remarks. The specimens agree well with the previous descriptions and illustrations. The species was not previously recorded from Mayotte with certainty, although it ranges widely in the Indo-Pacific region. The specimen of MNHN-Na 17567 was collected together with 1 female of Harpilius consobrinus De Man, 1902 (MNHN-Na 17568) and 1 female of Periclimenaeus zanzibaricus Bruce, 1969 (MNHN-Na 17569) at station 12. The specimen of MNHN-Na 16049 was collected together with 1 male of Cuapetes tenuipes ( Borradaile, 1898) (MNHN-Na 16041) and 3 ovigerous females of Jocaste japonica ( Ortmann, 1890) (MNHN-Na 17063) at Station 3. The specimen of MNHN-Na 17555 was collected together with 1 male of Harpiliopsis depressa ( Stimpson, 1860) (MNHN- Na 16061) at Station 32.
