Typhlatya


Typhlatya is a genus of shrimp in the family Atyidae. These are small, stygobitic shrimp found in the West Mediterranean region, Caribbean region, Ascension Island and the Galápagos, although the individual species often have very small ranges. Species in this genus are found in salt, brackish and fresh waters, mostly in anchialine habitats and none in the open sea.

Taxonomy, species and conservation

There are currently 17 recognized species, of which one is listed by the IUCN as critically endangered, and six are considered vulnerable. Phylogenetic studies indicate that the genus as presently defined is paraphyletic and needs to be redefined, as T. galapagensis clusters with the widespread Antecaridina and T. monae likely with the Australian Stygiocaris. On a higher level, these three genera, together with Halocaridina and Halocaridinides, form a group. In addition to the species below, "Typhlatya" jusbaschjani and "Typhlatya" pretneri have been listed in this genus, but the former is a species inquirenda and recent authorities generally include the latter in Troglocaris.
