NEW RECORDS: PERU: Ayacucho Department: Huamanga Province: Vinchos, 13 ° 19 ' 13 " S 74 ° 20 ' 53 " W, 3379 m, 20.xii.2007, J. Vitorino and J.A. Ochoa, 1 ♂, 1 ♀, 1 juv. ( AMNH); Wari ruins, 13 ° 03 ' 25 " S 74 ° 11 ' 53 " W, 2736 m, ii.2005, E. Escobar, 1 subad. ♂, 1 subad. ♀ ( AMNH); 21.xii.2007, J. Vitorino and J.A. Ochoa, 1 ♂, 1 ♀ ( AMNH).

DIAGNOSIS: Hadruroides bustamantei appears to be most closely related to H. mauryi , with which it was previously confused. The two species are similar in hemispermatophore dimensions; pectinal tooth count; carination of sternite VII and metasomal segments; and the curvature of the pedipalp chela fixed finger of the adult male, which creates a welldeveloped proximal gap with the movable finger when the fingers are closed, that is also present but less developed in females. They may be distinguished from one another based on the dimensions of the male pedipalp chela and the pigmentation pattern of the tergites and legs. The length:width ratio of the chela (♂) varies from 3.09 to 3.36 in H. bustamantei and from 2.7 to 2.8 in H. mauryi . Tergites I–IV display pairs of dorsosubmedian and dorsolateral spots, forming four distinct stripes along the mesosoma, in H. bustamantei , whereas only faint spots are evident along the posterior margin of each tergite in H. mauryi . Additionally, several spots are evident on the prolateral side of legs I–IV in H. bustamantei , whereas the legs of H. mauryi are unpigmented.

.

DISTRIBUTION: Hadruroides bustamantei is endemic to inter-Andean valleys in the Ayacucho and Huancavelica departments of central Peru (fig. 1). We provide new records at elevations between 2600 and 3379 m. The known locality records correspond to the Valles Interandinos Cálidos biogeographical zone ( Ceballos Bendezú, 1976; Ochoa, 2005). Recently reported records of H. maculatus from Huancayo (3200 m) in the Junín Department of the Peruvian central Andes ( Soleglad and Sissom, 2001; Soleglad and Fet, 2003a, 2003b; Fet et al., 2004; Fet and Soleglad, 2008) are probably referable to H. bustamantei .

ECOLOGY: Hadruroides bustamantei inhabits rocky areas with sparse xerophytic vegetation, comprising shrubs and cacti.
