Habitat

Brachoria divicuma specimens were collected during the day (11:30) in a maple and tulip poplar forest near a small stream.  Individuals were found on a steep slope near the flowing waters of Campbell Hollow.  No other xystodesmids were encountered sympatrically.  Note: Individuals of B. divicuma may be confused in the field with B. initialis (whose range overlaps with B. divicuma, but was not found co-occurring).

Distribution

Known from the Cumberland Plateau in Tennessee (Fentress and Morgan counties) and 27 km north in the Plateau Escarpment in Kentucky (McCreary and Pulaski counties).  The closest known Brachoria species, B. initialis and B. kentuckiana occur about eight air km southwest and 18 air km east.

Conservation status

Brachoria divicuma is threatened by habitat loss due to agriculture (especially growing demand for paper products), coal mining, development, and the invasion of exotic species.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
