Rissoella elatior Golikov, Gulbin & Sirenko, 1987

Native status

Living on seagrass.

Distribution

China, Japan, Russia.

Notes

The shell characteristics of the genus Rissoella are thin; vitreous and soft parts can be seen through it. As some species are similar in morphology, many species are misidentified or undescribed. In this study, our sampled material agrees with the original description of this species ( Golikov et al. 1987), as well as the study from Siaden et al. (2019).

Diagnosis

Shell minute (1.5 ± 0.12 mm in height, 0.88 ± 0.06 mm in width), elongate oval, thin, vitreous, fragile, translucent (Fig. 18 ). Whorls about 4, each whorl rather convex, spire about 25% of shell height. With deep sutures. Surface almost smooth, the axial growth lines of body whorl shrinking at base. Protoconch smooth, low. Aperture simple, ovate. With narrow umbilicus.
