The Cumberland Mountain Mimic MillipedePaul Marek
Brachoria cumberlandmountainensis individuals are about 47.3 mm long and 10.5 mm wide (females 47.7 mm X 11.0 mm). Color: 3-spotted yellow (10YR 7/14, shown above) or red (8.75R 5/14); and 2-spotted red (10R 5/12).

HabitatBrachoria cumberlandmountainensis specimens were collected during the day (14:00) in a moist forest comprising tulip, maple, and oak trees on the north-facing slope of Cumberland Mountain. Millipedes were found in a large bowl-shaped region just north of the ridge of the mountain (and through a wagonroad tunnel dynamited in the mountain for passage of wagons). Individuals were found beneath layers of decomposing leaf material under thick swathes of Urtica and Impatiens. Other xystodesmids encountered co-occurring with B. cumberlandmountainensis were Apheloria virginiensis corrugata and Gyalostethus monticolens. Note: Individuals of B. cumberlandmountainensis may be confused in the field with Apheloria virginiensis corrugata due to similarity in color patterns. Gyalostethus monticolens is easy to distinguish; it has an olive drab color and a body length about 1/2 that of B. cumberlandmountainensis.
DistributionKnown only from the type locality in Harlan Co., Kentucky. The closest known Brachoria species, B. dentata, occurs about 0.7 air km NNE further down the trail amongst spectacular room-sized boulders covered with Impatiens and Urtica.
Conservation statusBrachoria cumberlandmountainensis is threatened by habitat loss due to agriculture (especially growing demand for paper products), coal mining, development, and the invasion of exotic species.
