Platyrhacidae is a family of polydesmidan millipedes distributed in Southeast Asia and tropical Central and South America.
==Description== Platyrhacids are often large and colorful. They can be distinguished from most other polydesmidans by having ozopores situated further inward from the paranota margins, ozopores surrounded by a broad, flat ring, and presence of compound setae on the labrum and often on the epiproct (a posterior extension of the telson). The gonopods in males are relatively simple, although up to five gonopodal processes ("branches") may be present in some genera from Borneo. Large platyrhacids in Borneo may grow up to long and exhibit colors of blue, green, and yellow with black spots or stripes. The largest known species in the order Polydesmida, however, is a platyrhacid species found in Sumatra, Gigantorhacus mirandus, which can reach 134 mm (5.3 in) in length.
