Geosesarma aedituens, a new terrestrial crab (Crustacea: Decapoda: Brachyura: Sesarmidae) from Bali, Indonesia

Abstract

A new species of Geosesarma is here described from the island of Bali, Indonesia. This is the first species of this genus to be reported from the Island. Geosesarma aedituens, new species, is compared with its congeners, especially with the morphologically similar G. aurantium from Sabah, Borneo, G. serenei from Peninsular Malaysia and another four species occurring in the neighbouring island of Java. This species is found to be different based on the following diagnostic characters: extent of external orbital angles, movable finger on the chela, and G1 structure. © National University of Singapore.
