Abstract. â€” Nine species of pseudoscorpions associated with living and dead <br /><br />slash pine, Pinus elliottii Eng., in south central Florida were studied with respect <br /><br />to distribution and species diversity. Trees offering the greatest diversity of bark <br /><br />microhabitats have the greatest species diversity. Most of this diversity is in the <br /><br />fauna of the flake bark, which is the commonest and least patchily distributed <br /><br />bark microhabitat. However, some species may be unable to utilize this micro- <br /><br />habitat unless other types of bark microhabitats are available simultaneously.
