Latia neritoides is a species of small freshwater snail or limpet, an aquatic gastropod mollusc in the family Latiidae.
The type specimen is in the British Museum.
The specific epithet "neritoides" means "like a nerite". The shell of this species has an internal shelf or lamella, but it more closely resembles a shell of a Crepidula than it does a Nerita.
This species is endemic to the North Island of New Zealand.
This limpet lives in clean running streams and rivers.
The length of the shell is up to 11 mm. The width of the shell is up to 8 mm. The height of the shell is up to 4.5 mm.
The length of the shell is 8.5 mm. The width of the shell is 6 mm. The height of the shell is 3 mm.
The shell is semiovate, thin and fragile, almost smooth, brown, semitransparent. Sculpture consisting of microscopic rather distant radiate striae, and fine dense concentric growth-lines. Colour pale to dark brown; interior dark brown in the centre, the lamina white. Apex posterior, extending a little beyond the margin, with a spiral nucleus of 1 whorl, visible on the right side. The apex is generally on the left side, but sometimes near the middle of the posterior margin.
The aperture is large, oval, the thin sharp margin generally rounded, but the posterior part of it is occasionally straightened and forming more or less distinct angles with the lateral sides, which themselves may become almost straight. The inside is polished. The lamella has the left attached end near the middle of the left margin, but the right free end does not extend beyond the posterior third of the length of the shell.
