DIAGNOSIS: Hadruroides carinatus appears to be most closely related to H. geckoi , from which it may be distinguished based on the carination of sternite VII and metasomal segment V. Sternite VII exhibits four welldeveloped carinae in H. carinatus , but only the VL carinae are distinct (the VSM carinae are obsolete) in H. geckoi . The DL carinae of segment V are acarinate in H. carinatus , but comprise some granules in H. geckoi . Other differences between the two species are as follows: the pedipalp chela and metasomal segment V are longer in H. geckoi than in H. carinatus ; metasomal segment V exhibits fewer dorsolateral and ventrolateral setae in H. carinatus than H. geckoi ; the telson is entirely smooth in female H. carinatus , compared with H. geckoi , in which the ventral surface is granular; the lamina of the hemispermatophore is acuminate apically in H. geckoi , but rounded in H. carinatus .

DISTRIBUTION: Hadruroides carinatus was previously known only from the type locality, situated at 2650 m, near the city of Cajamarca. Based on new material collected during recent fieldwork, we confirm the presence of this species at Baños del Inca and report additional records between 2037 and 2880 m. The known locality records occur in the interAndean valleys of southern Cajamarca Department (fig. 2). Lourenço and Dastych’s (2001) record of H. carinatus from Chala (Arequipa Department in southern Peru) is probably a misidentification. Chala is situated at 350–500 m near the coast and H. carinatus inhabits mountainous regions in northern Peru.

ECOLOGY: This species is restricted to rocky areas with thornbush vegetation. Some specimens were collected under stones during daytime, others with UV light detection at night.
