Abstract
 A new genus and new species of the family Camptandriidae Stimpson, 1858, are described from Lower Kinabatangan-Segama Wetlands, Sabah, Malaysia. Exagorium fidelisi, new genus & species, can be distinguished from known camptandriid genera and species by the characters of the carapace, male abdomen and male first gonopod.

Key words. Taxonomy, new genus and species, Camptandriidae, Sabah, Malaysia


TAXONOMY
Superfamily Ocypodoidea Rafinesque, 1815
Family Camptandriidae Stimpson, 1858

Exagorium, new genus
Type species. Exagorium fidelisi, new species, by present destination. Gender neuter.

Etymology. The genus name “Exagorium” is derived from an arbitrary combination of hexagonal shape of the carapace of the type species (L. exagonum) and a suffix for the type genus of the family Camptandriidae “-rium”.

Exagorium fidelisi, new species

Etymology. The species name is dedicated to Fidelis Edwin Bajau, Deputy Director (Development) of the Sabah Forestry Department, who has facilitated and encouraged the authors’ study to a great extent.

Ecological note. Exagorium fidelisi, new species, was pulled up by a yabbie pump from small vertical burrows that were observed on the surface of muddy sediment with depths of 10–30 cm during low tide. It was found beside the Kulamba River, dominated by the clump-forming palm, Nypa fruticans (Fig. 6).
