DIAGNOSIS: Hadruroides mauryi appears to be most closely related to H. bustamantei , 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 curvature of the pedipalp chela fixed finger of the adult male, which creates a well developed proximal gap with the movable finger when the fingers are closed, that is also present but less developed in females. The two species may be distinguished 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 3.09–3.36 in H. bustamantei and from 2.7–2.8 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 depigmented.

DISTRIBUTION: Although the type series of H. mauryi comprises specimens from the Ayacucho, Cusco, and Huancavelica departments, the paratypes from Ayacucho and Huancavelica are not conspecific with the holotype from Paruro (Cusco Department), but are instead referable to H. bustamantei ( Ochoa and Chaparro, 2008) . Based on data gathered during the course of this study, we confirm that H. mauryi is endemic to the Cusco Department (fig. 2), where it occurs in inter-Andean valleys from 2830–3100 m.

ECOLOGY: Hadruroides mauryi is endemic to the Queswa biogeographical region ( Ceballos Bendezú, 1976; Ochoa, 2005), the vegetation of which is characterized by abundant cacti, shrubs, and small trees including Alnus acuminata Kunth (Betulaceae) , Cedrela lilloi C. DC. (Meliaceae) , Escallonia resinosa (Ruiz and Pav.) Pers. (Escalloniaceae) , Schinus sp. (Anacardiaceae) ( Marin Moreno, 1961). Hadruroides mauryi has been collected under stones and is syntopic with the bothriurid, Brachistosternus andinus Chamberlin, 1916 , and the buthid, Tityus footei Chamberlin, 1916 .
