The Natural Bridge Mimic MillipedePaul Marek
Brachoria plecta individuals are about 44.1 mm long and 10.5 mm wide (females 43.8 X 10.5 mm). Color: 3-spotted yellow (2.5Y 8/12), medial metatergal spots light pinkish orange (7.5R 6/10).

HabitatBrachoria plecta specimens were collected during the day (17:00) in a moist forest comprising hemlock, maple, oak, and birch trees. Individuals were found beneath layers of decomposing leaf material, predominately oak, about 60 m above (west) Upper Hood Branch. Other xystodesmids encountered sympatrically at this locality: Rudiloria guyandotta (coloration similar to B. plecta 3-spotted morph) and Apheloria virginiensis corrugata (coloration dissimilar to B. plecta banded yellow). Note: Individuals of B. plecta may be confused in the field with Rudiloria guyandotta due to similarity in color patterns.
DistributionKnown only from the type locality in Powell Co., Kentucky. The closest known Brachoria species, B. indianae, occurs about 30 km southwest in Irvine, Estill Co., Kentucky.
Conservation statusBrachoria plecta is threatened by habitat loss due to agriculture (especially growing demand for paper products), coal mining, development, and the invasion of exotic species.
