Cryptomya (Cryptomya) busoensis M. Yokoyama, 1922  — Huber, 2010: 461 (text-fig.).

Material examined. MBM078482 (specimen broken into small fragments and not figured, therefore), South Yellow Sea, Station 3056 (35 °N, 119 ° 45 ’E), 45m, in mud, collected by Lv, on October 27 th, 1958.

Distribution and habitat. Miocene to Recent. Yellow Sea, Lianyungang, China; Japan; Korea; Russia. Mud bottom in intertidal zone to 60m depth. Occurs in macrosymbiotic association with thalassinoidean shrimps ( Itani & Kato 2002; Nara & Kotake 1997; Nara et al. 2008).

Type locality. Otake, Chiba Prefecture, Honshu, Japan, Pleistocene.

Diagnosis. Length to 15 mm; shell laterally compressed, elongate; umbo low, situated subcentral; posterior area bound anteriorly by radial ridge; sculpture of thin commarginal lines; hinge of left valve with a large triangular chondrophore; pallial sinus not reaching further anterior than posterior adductor scar or lacking; pallial line continuous, obscure.

Remarks. This species was previously regarded as a synonym of C. californica  ( Bernard 1983; Coan et al. 2000), but is now recognized as a distinct species distinguished by its smaller and more elongate shell ( Coan & Valentich-Scott 2012; Huber 2010).
