A new species, Solemya (Solemya) flava, is described from a hydrothermal vent field located in the Iheya Ridge in the mid Okinawa Trough, Japan. The small-sized new species is characterized by (1) a branched internal ligament attached to the chondrophore, (2) a bright yellowish brown periostracum, and (3) relatively short shell length relative to height (length/height = ca. 2.2) for solemyid bivalves. This species is associated with a vesicomyid clam, Calyptogena okutanii Kojima and Ohta, 1997, which is dominant in chemosynthetic environments.
