The Silver City Mimic MillipedePaul Marek
Brachoria evides individuals are about 42.1 mm long and 11.6 mm wide (females 44.1 mm X 11.8 mm). Color: 2-spotted pink (shown above); and 3 spotted yellow (both morphs have a faint purple metatergal stripe with white caudal border)

HabitatBrachoria evides specimens were collected during the day (11:30) in a maple forested slope near a small stream. Individuals of the species were recorded from cedar woods (like B. cedra) in Greene County, Tennessee by Leslie Hubricht. No other xystodesmids were encountered sympatrically. Note: Individuals of B. evides may be confused in the field with B. mendota (whose range overlaps with B. evides, but was not found co-occurring).
DistributionKnown only from the four sites in Hamblen, Hawkins, Jefferson and Greene counties in Tennessee. The closest known Brachoria species, B. mendota and B. hendrixsoni occur about 30 air km west and east of the center of B. evides distribution.
Conservation statusBrachoria evides is threatened by habitat loss due to agriculture (especially growing demand for paper products), coal mining, development, and the invasion of exotic species.
