Abstract　Aspecies of thefamily Teutoniidae Koenike, 1910, whichis a new recordtoChina, is described: Teutonia (Sub
teutonia) piloseta. Thepectinatedpeglikesetae, the number of palpalsetae and onlypartiallysurrounded (open medially) Ep
Ⅳeasily distinguishthisspeciesfromothersinthe group. The disposition of glandularia andoculariainthe newspecies are de
scribed andillustratedin detail.
Key words　Acari, Lebertioidea, Teutoniidae, Teutonia, newspecies, new record.
