Doratodesmidae Cook, 1896 Haplodesmidae is a family of millipedes in the order Polydesmida.

[2] The tergites are always very convex, often with elaborate sculpturing in the form of two to four transverse rows of tubercles.

[2] The sterna are so narrow that the walking legs are contiguous where they emerge from the body.

The gonopods emerge from an aperture that is relatively modest in size and shaped like a transverse oval.

Species in this family hold their gonopods parallel to the main axis of the body in a considerable hollow in the middle of the ventral surface.
