Records from the eastern Pacific (e.g., Tres Marías Archipelago, Mexico) refer to other species ( Christoffersen 1979, 1998; Holthuis et al. 1980; Manning & Chace 1990; A. Anker, pers. comm.).

Ecological notes. Reefs and generally hard bottoms, under rocks covered with algae and hydrozoans, in tide pools, in rock crevices, in concretions of calcareous algae, in sabellariid reefs, on jetties among barnacles, etc. Salinity range: 28–41 psu. Depth range: intertidal to 75 m ( Christoffersen 1979).

Previous records. locality not informed ( Coutière 1909, as Synalpheus fritzmülleri elongatus Coutière, 1909 ). “Continental Platform” (= Plataforma, Salvador, Hartt Explorations) ( Christoffersen 1979, as S. fritzmuelleri ), Salvador, Itaparica Island and Abrolhos (R/V Calypso, St. 85) ( Christoffersen 1979, as S. fritzmuellerii ); Ilhéus (Almeida et al. 2006); Camamu Bay ( Almeida et al. 2007b, as Synalpheus cf. fritzmuelleri ).

Remarks. Synalpheus fritzmuelleri is morphologically quite variable and may require a more thorough study integrating both morphology and DNA (A. Anker, pers. com.).
