Three species of the processid shrimp genus Ambidexter are reported from Panama. Ambidexter symmetricus Manning & Chace, 1971, was collected from Thalassia grass flats on the Caribbean coast. Two new species are described from the eastern Pacific in the Bay
of Panama, one of which is also known from California. One species was collected from intertidal tidepools and the other from small burrows in the mid-intertidal zone of sand-mud beaches. These three are the only species of the genus known to date.
