Georissa biangulata is a species of minute cave snails that have an operculum. They are gastropod mollusks in the family Hydrocenidae.
Georissa is a genus of minute land snails, terrestrial gastropod mollusks in the family Hydrocenidae. Although the species are best known for living on the surface of limestone rocks, they are often also found in and on the vegetation and on non-calcareous rocks. One species, Georissa filiasaulae, is cavernicolous. It is only known from two caves in the Sepulut area of Sabah, Malaysian Borneo, where its above-ground sister species, Georissa saulae, inhabits the rocks outside of the cave, and is connected to the cave snail via narrow zones of hybridization at the cave entrances. Possibly, G. filiasaulae has evolved without ever having been fully separated from its ancestor, a process known as speciation-with-gene-flow.

Diplommatinidae is a family of small land snails, also known as staircase snails, with an operculum, terrestrial gastropod mollusks in the superfamily Cyclophoroidea. The Cochlostomatinae Kobelt, 1902, were previously considered a subfamily of the Diplommatinidae, but are now known to be a separate family.

Acmella nana is a species of land snail discovered from Borneo, Malaysia, in 2015. It was described by Jaap J. Vermeulen of the JK Art and Science in Leiden, Thor-Seng Liew of the Institute for Tropical Biology and Conservation at the Universiti Malaysia Sabah, and Menno Schilthuizen of the Naturalis Biodiversity Center in Leiden. It was named nana due to its minute size. Measuring only 0.7 millimeters in size, it is the smallest known land snail as of 2015. It surpasses the earlier record attributed to Angustopila dominikae, which is 0.86 mm in size, described from China in September 2015.
