History

When Michael Türkay revised the Gecarcinidae family in 1974, the G. humei species was originally classified as a junior synonym of the G. lalandii species. However, due to differences in physical characteristics and distribution, G. humei became recognised as an independent species to G. lalandii in 2017.
