This species is similar to Austropeplea spp. but differs in its taller spire, more defined sutures, and the raised lower part of the inner lip forming a shelf over the umbilical area.

Original name: Lymnaea viridis Quoy & Gaimard, 1832. In Quoy, J. R. & Gaimard, J. P.(1832). Zoologie, Mollusques, Vol.2. Voyage de Découvertes de L' Astrolabe execute par Ordre du Roi, Pendant le Années 1826 - 1829, sous le commandment de M.J. Dumont d'Urville. Paris : J. Tastu. 1-320pp.
Type locality: Guam.
The taxonomic position of this species has been problematic. The genus Orientogalba Kruglov & Starobogatov, 1985 (with Viridigalba Kruglov & Starobogatov, 1985 a synonym) is used here following Aksenova et al. (2018). This species has previously been placed in Austropeplea (see Ponder & Waterhouse, 1997 for discussion) and Radix.
On water weeds and similar substrates along edges of streams often on damp mud above water line. Sometimes common but known from only a few localities at the present time. The species appears to be spreading in New South Wales. Feeds on algae and detritus. Egg mass a crescent- shaped jelly strip containing many small eggs. Development direct.
Introduced from Southeast Asia into creeks in Sydney and Newcastle, New South Wales (Shea, 1995) and Brisbane (Boray, 1978), Queensland, also recorded from an aquarium in Tasmania (Kershaw, 1991) and from south Western Australia. Probably more widespread than records indicate.
Like Austropeplea tomentosa, this species is a host of Liver Fluke (Fasciola hepatica), a parasite that infects stock and sometimes humans.
