Paropisthopatus is a monospecific genus of velvet worm containing the single species Paropisthopatus umbrinus. [1] Females of this species range from 20 mm to 70 mm in length. [2] The type locality is in central Chile. [3] Velvet worms in this genus have 16 pairs of legs. [4] This genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta. [5]

A second species assigned to this genus, Paropisthopatus costesi(Gravier & Fage, 1925), is considered a nomen dubium by Oliveira et al., 2012.
