Nozeba was named by Iredale (1915) [Sepkoski's age data: K Camp R Sepkoski's reference number: 1066 Sepkoski's age data: T Plio R Sepkoski's reference number: 909]. It is extant. Its type is Rissoa emarginata.

It was assigned to Iravadiidae by Ponder (1984), Beu et al. (1990), Wilson (1993), Lozouet (1998); and to Neotaenioglossa by Sepkoski (2002).

Diagnosis
ReferenceDiagnosis
W. F. Ponder 1984Ovate to elongatelyconical, surface glossy, non-umbilicate, rather solid, smooth or with spiral threads, sometimes spirals moderately strong on base. Aperture rounded to distinctly-excavated anteriorly, sharply-angled posteriorly but not channelled. Posterior corner of aperture turned forward slightly, rest of outer lip approximately orthocline; inner lip partially disconnected from parietal wall in some species. No external varix. Protoconch smooth, of 2- 24 convex whorls, flattened on top, last whorl descending, apex partially immersed. Periostracum thin. Fig. 19A, C-E, I. Head-foot. Cephalic tentacles long, strap-like, nonpigmented, with the eyes in small bulges at their outer bases; a few stiff "setae" distally. Snout moderately long, extensile, bilobed. Foot slightly pigmented dorsally, with weaklycleft anterior edge onto which opens a conspicuous, triangular anterior mucous gland; no posterior mucous gland present. Posterior palliai tentacle very short; no anterior palliai tentacle or metapodial tentacle. Posterodorsal side of foot simple. (/. topaziaca, Port Hacking, New South Wales). Fig. II.
