Synonymy: 1957, N.Z. Geol. Surv. paleont. bull. 28: 37, pl. 9, fig. 183, 184 (Nonion, Florilus, Nonionellina).
Description: Planispiral, smooth and glossy, fairly strongly inflated, sutures moderately indented, aperture simple at base of chamber, umbilicus on both sides covered by a branching lobe.
Distribution: Waiauan to Recent.
Comment: This species, with its umbilical lobes and planispiral habit does not fit well into any existing generic diagnosis. It is here regarded as a symmetrical Nonionella. See Lewis & Jenkins, 1969, Micropaleontology 15(1): 1-12.
