A new montane species of Vaejovis C.L. Koch (Scorpiones: Vaejovidae) is described from the Si­erra Madre Occidental of Durango, Mexico. Vaejovis baggins Azzinnari, Bryson, Graham, Solís-Rojas, and Sissom, new species, is similar to mexicanus group species in the mountain range, including V. montanus Graham and Bryson, V. sierrae Sissom, Graham, Donaldson, and Bryson, and V. mcwesti Sissom, Graham, Donaldson, and Bryson, but differs from these species based on aspects of body size, pedipalp carination, chelae granulation, morphometrics, and setal patterns on the metasoma. A molecular clock estimate indi­cates that the new species shared a common ancestor with V. mcwesti during the late Miocene or Pliocene.
