Reference: Hornibrook, Brazier & Strong 1989, p.98, Fig. 19:6 (Holotype).
Synonymy: 1961, N.Z. Geol. Surv. paleont. bull. 34(1): 58, pl. 8, fig. 135.
Description: Distinguished by the elongate, relatively slender, biserial test with steeply sloping chambers.
Distribution: Duntroonian to lower Otaian.
Comment: The variability of Polymorphinas makes consistent grouping into distinct taxa difficult. Although members of some populations show intermediate characters of P. marwicki and P. waitakiensis, the latter has been found more widely distributed.
