Bothriurus pichicuy, a new scorpion species from the center coast of Chile, is described. It belongs to the vittatus species-group, and differs from the others species in the group by the pigmentation patterns of the prosoma, mesosoma and venter of metasoma, by the development and arrangement of the ventral keels of caudal segment V, and for its small size. The species is the only representative of the vittatus species-group that lives in sympatry with another Bothriurus species: B. coriaceus Pocock, 1893, from the coastal desert of Chile. Records of B. pichicuy came from the provinces of Petorca and Choapa.
