Remarks

Although Taylor and Wells (1994) synonymised C. kawamurai with Cheungbeia mindanensis ( Smith, 1877) , the latter (holotype, Figure 2H ) has a smoother appearance, C. kawamurai having coarser spiral sculpture, which forms low but distinct nodules where the spiral cords cross the axial ribs; the subsutural concavity is also deeper in kawamurai . A third member of this complex, Cheungbeia laterculata ( Sowerby 1870) (holotype, Figure 2I ), differs from both mindanensis and kawamurai in being (typically) strongly striped with dark brown or black, and in its stronger spiral ridges (which cross the intervals between the axial ribs), whose interstices bear a distinct spiral microsculpture, lacking in the other two species; C. laterculata also attains a larger size and has a more prominently alate outer lip.
