Synalpheus theano is an Indo-West Pacific snapping shrimp first described from between Pulau Misooi and Pulau Salawati, Indonesia (Chace 1988). For more details, see ABRS (2009): http://www.environment.gov.au/biodiversity/abrs/online-resources/fauna/a....
Synalpheus theano was first described by de Man (1910) from between Pulau Misooi and Pulau Salawati, Indonesia (Chace 1988), types stored at the Zoölogisch Museum, Universiteit van Amsterdam, Amsterdam, The Netherlands (ZMA). For additional descriptions, see Banner and Banner (1972, 1975), Chace (1988).
Specimens have been collected from dead corals and from sponges (including the species Psammoaplysilla purpurea), to 62 m depth (Banner and Banner 1975, Chace 1988).
Maximum body size is 22 mm (total length), 7 mm (carapace length) (Banner and Banner 1975, Chace 1988). Morphologically very similar to Synalpheus neptunus, but can be reliably distinguished from the latter by the tip of the third maxilliped, which bears a tuft of long, flexible setae (in S. theano) and in S. neptunus bears a circlet of short spines (Banner and Banner 1972).
Not Synalpheus theano (sensu Banner and Banner 1966, = S. neptunus).
Indo-West Pacific: Australia, Indonesia, Singapore, Philippines (Banner and Banner 1975, Chace 1988).
