Doryphoribius smokiensis, a new species of Eutardigrada (Hypsibiidae) from the Great Smoky Mountains National Park, TN, USA (North America)

A new eutardigrade, Doryphoribius smokiensis sp. nov., is described from soil and leaf litter samples collected in the Great Smoky Mountains National Park in Tennessee, USA. The new species differs from two similar species (with two macroplacoids and a sculptured dorsal cuticle without gibbosities) by the presence of a very wide buccal tube (high buccal tube pt ratio: >20.0), absence of enlarged bases of claws, absence of eyes, and other morphological and morphometric characters.
