DIAGNOSIS: Orobothriurus parvus is most closely related to O. wawita (fig. 5). Both species share similar hemispermatophore morphology, including an elongated lamina apex and a short frontal crest (fig. 27B, C). The reticulate pigmentation along the metasomal DL carinae (figs. 12B, 13C) and the macrosetal counts on the ventral surface of the metasoma are also similar. The following characters separate the two species. The pedipalp chela manus of the male O. parvus possesses an apophysis on the internal surface, and the fixed finger is slightly curved, creating a small gap with the movable finger when the fingers are closed (fig. 26A), whereas the apophysis is absent and the fixed finger straight, such that no gap is evident when the fingers are closed, in the male of O. wawita (fig. 25B, C). The VL and VM carinae of metasomal segment V are complete in O. parvus (fig. 22E), but absent (♂) or restricted to the distal third of the segment (♀) in O. wawita (figs. 21C, 22F). Metasomal segments II–V exhibit a distinct VM pigmentation stripe in O. parvus that is absent in O. wawita (fig. 13D). The two species also differ in the shape of the ventral margin of the hemispermatophore apex, which is inclined to the dorsal surface and curved distally in O. parvus (fig. 27B), but straight in O. wawita (fig. 27C).

DISTRIBUTION: Orobothriurus parvus is endemic to the central Andes, recorded from 3400–4750 m, in the Junín and Lima departments, Peru (figs. 2E, 52).

ECOLOGY: The area inhabited by O. parvus corresponds to the Puna ecoregion or Puna biogeographical province ( Brack, 1986; Ceballos Bendezu, 1976). The typical Puna vegetation of this area comprises shrub, steppe, and grasses (fig. 2E). No other scorpion species have been recorded in sympatry with O. parvus .

REMARKS: Orobothriurus parvus was misidentified in several papers as Bothriurus borellianus , Bothriurus chilensis or Bothriurus (Andibothriurus) peruvianus ( Bücherl, 1959b; Aguilar and Meneses, 1970; Francke, 1974). A record from Colcabamba ( Lourenço and Dastych, 2001: 54), based on a single female, requires confirmation.
