Description

The holotype adult female specimen is just over 8 millimetres long, which is extremely small for the order, it is distinguished by the presence of 35 cylindrical body rings with free sternites and fused tergites, among other characters.[1]

Discovery

The specimen was discovered in Burmese amber, a productive amber deposit in Kachin State, which has been dated to earliest Cenomanian, or approximately 99 million years old. As of the time of publication, it is the only known callipodid in the Burmese amber out of 529 known millipede specimens, most of which belong to extant families and even genera.

gollark: I think the reason the small ones work better is due to the higher variance.
gollark: They *can't* keep growing, in an 8x8 grid, though.
gollark: (they do wrap)
