See text Sinocallipus is a genus of predominantly cave-dwelling millipedes in the order Callipodida.

Five of the six known species are found in limestone caves on the Indochinese Peninsula from Vietnam to southern China, and it is the only callipodidan genus entirely confined to the tropics.

[1] In contrast to many other millipede groups, the gonopods (reproductive legs) of Sinocallipus show little variation between species, while other characters such as color, size, and other body parts differ more noticeably between species.

[1] All species except S. thai have been collected solely from caves, and show troglomorphic (cave-adapted) traits such as pale coloration, long antennae, and long legs.

S. thai is unique for its dark coloration and terrestrial habitat, and correspondingly has the most ocelli and shortest antennae.
