DIAGNOSIS: Hadruroides charcasus may be distinguished from all other species of the genus by means of the carination of the pedipalp chela. The internomedian, dorsointernal, and dorsal marginal carinae are well developed, comprising strong granules in adult H. charcasus, compared with other species of Hadruroides, in which the pedipalp chela is acarinate.
DISTRIBUTION: Hadruroides charcasus is widely distributed throughout northern Peru. It has been recorded from the Lambayeque, Piura, and Tumbes departments, as well as the western slopes of the Andes in Cajamarca Department (Maury, 1975; Francke, 1977). Specimens examined during the present study were collected at elevations between 15 and 498 m (fig. 2). It is doubtful whether this species occurs in the inter-Andean valleys on the eastern side of the Cordillera. Maury’s (1975) record from Baños del Inca (2660 m, Cajamarca Department) is probably erroneous. We conducted several field expeditions to the Cajamarca region and H. carinatus was the only Hadruroides species collected at Baños del Inca. Other records from Cajamarca, Trujillo, Tumbes, and Lobos de Afuera (Maury, 1975; Francke, 1977) should be reassessed.
ECOLOGY: The vegetation in the region inhabited by H. charcasus is characterized by cacti, shrubs, and scattered trees, e.g., Bursera graveolens (Kunth) Triana and Planch. (Burseraceae), Capparis sp. (Brassicaceae), Ceiba insignis (Kunth) Gibbs and Semir (Malvaceae), Loxopterigium huasango Spruce ex Engl. (Anacardiaceae), Prosopis pallida (Humboldt and Bonpland ex Willdenow) Kunth (Fabaceae). Hadruroides charcasus is sympatric with H. leopardus.
