NEW RECORDS: ARGENTINA: La Rioja Province: Famatina Department: Sierra de Famatina, Cuevas de Noronha (path to La Mejicana mine), 28 ° 559310 S 67 ° 409230W, 2846 m, 29.i.2006, L. Piacentini, L. Compagnucci, and A. Ojanguren Affilastro, 2 ♂, 6 ♀, 12 juv. (MACN-Ar), 2 ♀ ( AMNH [LP 5846]).

DIAGNOSIS: Orobothriurus famatina is most closely related to O. calchaqui (fig. 5), from which it differs in the following respects. Orobothriurus famatina possesses one ML macroseta on metasomal segment IV and only 10 % of the specimens possess one DL macroseta on segment III (absent in 90 %), whereas O. calchaqui possesses two or three macrosetae on segment IV and 70 % of the specimens possess one DL macroseta on segment III (absent in 30 %). There are also differences in the trichobothrial pattern. Pedipalpal chela trichobothria db and Et 3 are located in the same axis as, or slightly distal to Est in 70 % and 30 % of the specimens of O. famatina , respectively, but always located proximal to Est in O. calchaqui . Pedipalp patella trichobothrium em 2 is located in the same axis as, or distal to em 1 in 70 % of the specimens of O. famatina , but proximal to em 1 in 80 % of the specimens of O. calchaqui . Orobothriurus famatina may be differentiated from O. compagnucci by the more elongated apex of the hemispermatophore lamina: the apex comprises 66.6– 68.48 % (n 5 3, mean 5 67.02 %) of the lamina in O. famatina (fig. 36F–H) and 52.17 % –54.54 % (n 5 3; mean 5 52.98 %) in O. compagnuccii (fig. 36A–C). The two species can also be separated by the VL and VSM carinae of metasomal segment I and sternite VII in the male, which are well developed in O. famatina , and weakly developed to absent in O. compagnuccii (fig. 18F).

DISTRIBUTION: Orobothriurus famatina is known only from high altitudes (2500– 3200 m) of the Sierra Famatina, a mountain range close to the Andes, in La Rioja Province of central-western Argentina (figs. 3G, 54).

ECOLOGY: This species inhabits an area of grassland and shrub steppe that belongs to the Prepuna and Altoandina phytogeographic provinces ( Cabrera and Willink, 1980; fig. 3G). It occurs in sympatry with another bothriurid, Bothriurus olaen Acosta, 1997 ( Ojanguren Affilastro, 2005).
