A revision of the genus Typhlogastrura in North American caves with description of five new species
Kenneth Christiansen and Hanghang Wang


The peculiar troglobitic, polyphyletic nature of Typhlogastrura and the small amount of troglomorphism found in the genus is discussed. New features of chaetotaxy are systematized and used . The Nearctic members are distinguished, keyed out and five new species—asymmetrica, fousheensis, helleri, steinmanni and unica—are described. Species are shown to occur in 5 widely separated regions ranging from Colorado to Pennsylvania.
