Indo-West Pacific: Madagascar , Mauritius , Réunion , Seychelles , Red Sea, Persian Gulf, Gulf of Oman , Malaysia , Thailand , Indonesia , Philippines , and Australia . Regional records. PG : Iran ( Naderloo & Türkay 2012; present study ); GO : Iran (present study). Habitat. Sandy with rubble and rocky-sand flats, under rocks and large pieces of coral rubble; intertidal to 5 m deep. Remarks. This species is one of largest Alpheus in PG and GO (TL: 10 cm ). Small-sized specimens were free-living ( Fig. 2F ), but larger specimens ( Fig. 2E ) were found associated with the ophiuroid Macrophiothrix elongata Clark, 1938 . Furthermore, PG specimens differ from Singaporean specimens in color pattern (see Anker & De Grave, 2016 ). To clarify the species identity, a molecular analysis and thorough comparison of morphology and color patterns were applied on the present study material. Accordingly, these specimens were precisely categorized into “symbiont ” and “ non-symbiont ” A. edamensis (unpublished molecular data by authors based on COI sequencing).
