Ingolfiellida is an order of Peracaridan crustaceans, containing one suborder, Ingolfiellidea; both of these are monotypic, containing just one subordinate group.[1] Subordinate to these is infraorder Ingolfiellidamorpha.[2]
The two families, Ingolfiellidae and Metaingolfiellidae, are each considered to belong to their own monotypic parvorders and superfamilies.[3][2] Over 30 species are known from the two families.[4] These animals are small, vermiform (worm-like) crustaceans that live "in the soft mud of the deep-sea floor, as well as in high mountain freshwater riverbeds, or in subterranean fresh, brackish, and marine interstitial waters of continental ground waters and continental shelves".[5]
This taxon was previously considered a suborder of amphipods,[5] but in 2017 it was deemed distinct enough to be elevated into a separate order. The order's diagnosis noted several diagnostic traits, such as vestigial stalked eyes, the first and second pairs of gnathopods being "eucarpochelate",[a] the pleosome possessing 6 "relatively undifferentiated" segments, a lack of epimera, and reduced pleopods and uropods.[3]
