  ABSTRACT
  A Praobdellidae leech and its palm oasis environment is described from Baja California, Mexico. This leech is tentatively identified as Pintobdella cajali Caballero, 1932 by somite annulation and reproductive tract. Praobdellid records were noted in literature and museum from Baja California Sur and Arizona. Six leech species are noted from the Peninsula Range in southern California (five species) and Baja California (one species), five taxa in the Gila River drainage of Arizona and New Mexico, one species from Sonora, and three species from Sinaloa illustrating the effects of the region’s aridness and/or the paucity of leech surveys in northwestern Mexico.
