Karstarma is a genus of karst-dwelling crabs formerly included in Sesarmoides.

Description

Karstarma is distinguished from the closely related Sesarmoides by the lack of a stridulatory structure on the cheliped which is present in the latter genus.[3]

Ecology & biogeography

All species in the genus Karstarma are typically found in anchialine pools[3] across the Indo-Pacific.[2]

Taxonomy

The genus name Karstarma is derived from the word karst, in arbitrary combination with the genus name Sesarma.[3] It has been frequently misspelt Karstama, including in the original description.[2]

In the original description of the genus, 12 species were included.[3] Three species have since been added.[2][4] A new species, K. vulcan, was also described from Réunion in 2018; this species is unique from all others as it is found in the western Indian Ocean rather than the eastern Indian or Pacific Oceans.
