«Parvamussium vafer (MARWICK, 1931: 64, pl. 4, figs. 55-57; Middle Miocene, New Zealand) reaches a slightly larger size than P. bayosense n. sp., and is higher than long. It also differs from P. bayosense n. sp. in having only 8 commarginal costae per mm, 9 to 10 rather than 7 internal ribs, and more numerous radial ribs on the left valve.»
