Stygobromus is a genus of amphipod crustaceans that live in subterranean habitats. The majority of the listed species are endemic to North America (one from Canada, the rest from the United States), [3] a smaller number of species are also known from Eurasia. [4] Most of the North American species live in areas which were not covered by the Laurentide Ice Sheet, although a few species seem to have survived under the ice. [5] A number of species are on the IUCN Red List as endangered species (EN) or vulnerable species (VU); one species, S. lucifugus , is extinct.
Stygobromus includes the following species: [1]
Allocrangonyx is a genus of troglobitic amphipod crustaceans from the South Central United States. The two species are both listed as vulnerable on the IUCN Red List. The animals are blind and unpigmented. During the male's development, the outer ramus of the third uropod differentiates into secondary segments and grows to a length greater than the animal's body length.
Lirceus is a genus of isopod crustaceans in the family Asellidae that live in southern Canada and the eastern United States as far west as the Great Plains. Of the 15 species in the genus, two are listed as either endangered (EN) or vulnerable (VU) on the IUCN Red List.
