Karstarma
genus of crustaceans

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.
Ecology & biogeography
All species in the genus Karstarma are typically found in anchialine pools across the Indo-Pacific.
Taxonomy
The genus name Karstarma is derived from the word karst, in arbitrary combination with the genus name Sesarma. It has been frequently misspelt Karstama, including in the original description.
In the original description of the genus, 12 species were included. Three species have since been added. 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.
This brief starts where responsible research should: with the source description of “Karstarma” as genus of crustaceans. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of crustaceans. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 24, 2026. The linked authority identifier is Q18581545. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2018.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
