clade Hypsogastropoda Omphalotropis costulata Emberton & Pearce, 1999 "Omphalotropis sp.

nov. 2" is the name used by the IUCN for an undescribed species of minute salt marsh snail with an operculum, a terrestrial gastropod mollusk, or micromollusk, in the family Assimineidae.

Its natural habitat is subtropical or tropical dry forests.

The species was originally named O. costulata, but this name was previously used for another species and is therefore invalid.

As of 2012, the species lacks a proper binomial name.
