Synalpheus tumidomanus is an Indo-West Pacific and Indian Ocean snapping shrimp first described from Red Sea (ABRS 2009). For more details, see ABRS (2009): http://www.environment.gov.au/biodiversity/abrs/online-resources/fauna/a....
Alpheus tumidomanus (Paulson 1875); Synalpheus tumidomanus exilimanus (Coutiere 1909); Synalpheus hululensis (Coutiere 1908); Synalpheus hululensis hululensis (Crosnier and Forest 1966); Synalpheus mac-cullochi (Coutiere 1908); Synalpheus theophane (de Man 1911); Synalpheus anisocheir (Stebbing 1915); Synalpheus japonicus (Yokoya 1936); not Synalpheus tumidomanus (sensu Kubo 1940); not Synalpheus anisocheir (sensu Formanoir 1958).
This species has been collected in sponges and dead corals, intertidal to 148 m depth (Chace 1988).
Maximum body size is 9 mm (carapace length) (Chace 1988). Color likely varies; one specimen living in a sponge in the Red Sea was reported as grey-green, with dark fingers (reported in Banner and Banner 1981).
Synalpheus tumidomanus was first described as Alpheus tumidomanus by Paulson (1875) from the Red Sea. Much geographical and morphological variation has been described in this widespread species; for detailed table of this variation and list of synonomies, see Banner and Banner (1975). For additional descriptions, see Chace (1988).
Indo-West Pacific and Indian Ocean: widespread (under various names) in South Africa, Red Sea, Persian Gulf, Sri Lanka, Maldives, Singapore, Thailand, Indonesia, Philippines, Japan, and across the central Paicifc to the Phoenix archipelago; also reported from the Mediterranean coast of Israel (Banner and Banner 1975, Chace 1988).
