The Green River Mimic MillipedePaul Marek
Brachoria viridicolens individuals are about 41.3 mm long and 10.0 mm wide (females 42.4 mm X 10.5 mm). Color: 3-spotted yellow (5Y 8.5/10, shown above) or pink (7.5R 6/10); and combined striped/3-spotted yellow.

HabitatBrachoria viridicolens specimens were collected during the day and evening (14:00 and 19:00) in a maple forest near a small shaded tributary of Green River and in a dry oak forest next to Green River. Individuals were found beneath layers of decaying leaf material, predominately maple and oak. At the first locality, specimens were collected on the banks of a stream beneath stacks of maple leaves; whereas at the second locality, specimens were collected in moist depressions filled with decaying leaves at the bottom of a gully in an oak forest. One other xystodesmid encountered sympatrically at this locality is Apheloria virginiensis corrugata, which appears similar in coloration with the B. viridicolens 3-spotted-striped morph.
DistributionKnown only from the type locality in Green Co., Kentucky and 14 air km east on the western banks of the Green River in Taylor Co., KY. The closest known Brachoria species, B. electa and B. kentuckiana, occur about 80 air km northeast in Mercer County and about 80 air km southeast in Pulaski County, Kentucky.
Conservation statusBrachoria viridicolens is threatened by habitat loss due to agriculture (especially growing demand for paper products), coal mining, development, and the invasion of exotic species.
