Stygobromus Gracilipes
''Stygobromus'' is a genus of Amphipoda, amphipod crustaceans that live in subterranean habitats. As well as a large number of species in North America, a smaller number of species are also known from Eurasia.

A number of species are on the IUCN Red List as endangered species (EN) or vulnerable species (VU); all the listed species are endemism, endemic to the United States. One species, ''Stygobromus lucifugus, S. lucifugus'', is extinction, extinct. ''Stygobromus'' includes the following species: *''Stygobromus abditus'' Holsinger, 1978 (Virginia) *''Stygobromus ackerlyi'' Holsinger, 1978 (Georgia (U.S. state), Georgia) *''Stygobromus alabamensis'' (Stout, 1911) *''Stygobromus albapinus'' Taylor & Holsinger, 2011 (Nevada) *''Stygobromus allegheniensis'' (Holsinger, 1967) (New York (state), New York to West Virginia) *''St ...
