Brachoria hansonia individuals are about 44.0 mm long and 10.7 mm wide (females 47.2 X 11.2 mm). Color: 3-spotted light orange (7.5YR 7/12, shown above), pink (1.25YR 6/12), or yellow (3.75Y 8/12).

Habitat
Brachoria hansonia specimens were collected during the day (11:30) about five meters north of Little Clear Creek (Bell Co., Kentucky) in a hemlock, oak and birch forest. Millipedes were found beneath a thin layer of decaying leaves in a very flat section of the forest near the stream. No other xystodesmids were encountered with B. hansonia at this locality. However, B. hansonia and B. splendida co-occur at Pine Mountain State Park and appear similar in coloration.Distribution
Known only from six localities in eastern Whitley and western Bell counties, Kentucky. Brachoria hansonia occurs on Pine Mountain from Pine Mountain State Resort Park to Chenoa Lake. There is one, apparently disjunct population 23 air km west in Whitley County. The closest known Brachoria species (aside from B. splendida that co-occurs at Pine Mountain State Park and Kentucky Ridge State Forest) is B. sheari, which occurs about 14 air km southeast of B. hansonia at the base of Cumberland Mountain near Shillalah Creek.Conservation status
Brachoria hansonia is threatened by habitat loss due to agriculture (especially growing demand for paper products), coal mining, development, and the invasion of exotic species.References
