Six new species of Pseudotremia from caves of the Tennessee Cumberland Plateau (Diplopoda: Chordeumatida: Cleidogonidae)

Six new species of the milliped genus Pseudotremia are described and illustrated from caves of the Cumberland Plateau in east-central Tennessee (USA): Pseudotremia barri, P. garlandae, P. hollidayi, P. manni, P. roebuckorum, and P. wallaceae. The degree of troglomorphism in these species varies, leaving their ecological status as troglobites versus troglophiles uncertain. New records of P. acheron Shear and P. minos Shear are given, and the probable extinction of the Nickajack Cave population of P. eburnea Loomis is noted. Many species in Pseudotremia remain undescribed, making discussion of the zoogeography or evolution of the group inconclusive until the genus is better known.
