The giant isopod genus A. Milne-Edwards, 1879, is recorded for the first time in Indonesian waters, from deep waters off southern Java in the Indian Ocean. is described and notes on juvenile specimens of an unidentified species found in the same locality are also provided. is characterized by the large size (averaging at 330 mm), narrowly rounded clypeus apex, prominent longitudinal carina on the clypeus, convex lateral margins of the uropodal exopod and endopod, produced distolateral corners of the uropodal exopod and endopod which have acute ends, an uropodal exopod with a setal fringe of medium length (69%), a pleotelson 1.6 times wider than long with the posterior margin medially concave, and the large number (11-13) of spines on the pleotelson.

A new species of ghost shrimp, Ctenocheles sinicus, is described based on specimens recently collected from Taiwan Strait, the East China Sea, at a depth of 50 m. The new species is characterized by: the dorsally unarmed rostrum attaining one-third the length of the eyestalks; the rounded suborbital angle of the carapace; maxillipeds 2 and 3 each with a short exopod; the merus and ischium of pereopod 1 being unarmed along the lower margin; the major cheliped with fingers twice as long as the palm; the ischium of pereopod 2 armed with prominent spiniform setae along the lower margin; and the rounded anterodistal angle of uropodal exopod. The morphological differences between the new species and other congeners are discussed and a key to the species of Ctenocheles Kishinouye, 1926 is provided.

Purpose: The identification of the external attaching fish parasitic cymothoid, Nerocila phaiopleura Bleeker 1857, is still based on the brief description of Australian specimens provided by Bruce (1987). The present study aimed to provide a redescription and molecular characterisation of Indian specimens of N. phaiopleura.
