These differences included; a slightly sturdier body, smoother skin on the ventral surface and the greatest difference, the reproductive nature, laying the eggs outside of water. Until 2022, four other species in

were also classified in this genus, but a phylogenetic study reclassified them into the new genus '' Anstisia''. Species of ''Geocrinia'' develop initially in the egg then hatch when sufficient rain falls for them to complete their larval development in water, while ''Anstisia'' go through the tadpole stage entirely on land in the egg capsule.
