Relatively large cylindrical millipedes with 42‒54 body rings. Eyes are widely spaced, with more than twice the width of an eye between them. Base color ranges from dark blackish to dull reddish brown, with some species having bright red and yellow bands on the posterior margin of each ring. Male gonopods are normally concealed within a pouch.

Range

Range overlaps with Hiltonius from Kern County, CA to Baja. Tylobolus differs from Hiltonius by having more ocelli per eye (27‒50), a larger and hooked process on the coxa of the third legs in males, and sharper corners of the mandibular stipes. May be mistaken in photos for Narceus, a species complex widespread in eastern North America, but the two genera do not overlap.
