For the Mexican oniscideans of the family Armadillidae, 6 species of the genus Cubaris Brandt, 1833 and 18 species of the genus Venezillo Verhoeff, 1928 have been recorded. Of them, only Venezillo stuckchensis (Mulaik, 1960) has been registered for the Baja California Peninsula (BCP). This species was described upon a single male and no biological studies exist on this taxonomic entity since its original description in 1960. In this work, we redescribe V. stuckchensis including the designation of a neotype and paratopotypes using specimens from the type locality. We report this species from 5 additional wetlands of southern BCP in the state of Baja California Sur. The type locality is corrected in its formal name and its geographical location. The morphological identity of V. stuckchensis is documented using SEM micrographs, and data on its molecular identity with 16S ribosomal RNA mitochondrial gene fragments are given.
