Species of the genus Munidopsis are typically distributed in bathyal and abyssal zones, but the anchialine species Munidopsis polymorpha is an exception. It inhabits a volcanic tube on Lanzarote Island (Canary Islands, NE Atlantic) and is currently listed as endangered due to its highly restricted distribution and degree of endemism. Microsatellite loci were isolated from partial genomic libraries that had been enriched for AC, ACAG, GATA, AAAC and AAG repeat sequences. Eight loci were polymorphic in a sample of 24 individuals. The number of alleles per locus ranged from 2 to 4 with observed and expected heterozygosities ranging from 0.083 to 0.875 and from 0.080 to 0.681, respectively. These markers will be used to evaluate levels of genetic diversity and inbreeding, providing essential information for the development of a management and conservation strategy for this species.
