Distribution

Nansha Islands; Vietnam, Queensland to south-east India. Not previously recorded from the China Seas.

Remarks

Cheungbeia laterculata is very similar to C. kawamurai in shell profile, oblique axial ribs and shell colour (although typically with darker stripes), but differs in having more numerous spiral ridges crossing the axial ribs, which produces a coarser surface than the smooth surface of C. kawamurai . Cheungbeia laterculata was recorded from Taiwan by Chang and Wu (2000), who misidentified it as Inquisitor zonata (Reeve, 1843) , a species (probably referable to genus Ptychobela ) that differs from laterculata in its squarely truncate siphonal canal, spiral ridges that are weak between the axial ribs and a different colour pattern.
