Two deep-sea shark species were obtained as by-catch of the local fishery of the Patagonian toothfish,  Dissostichus eleginoides , at depths ranging from 1000 to 2200 m off central and northern Chile. A total of 19 parasite taxa were found in 133 specimens of the southern lanternshark,  Etmopterus granulosus , ( n  = 120) and largenose catshark,  Apristurus nasutus,  ( n  = 13). Fourteen taxa (four Monogenea, one Digenea, four Cestoda, one Nematoda, two Copepoda, one Annelida and one Thecostraca) were found in  E. granulosus , whereas five taxa (one Monogenea, two Cestoda and two Nematoda) were found in  A. nasutus . Representatives of Cestoda showed higher values of prevalence and a greater intensity of infection; this pattern is consistent with reports for elasmobranchs, but the monogenean richness was higher than that previously reported for related deep-sea sharks. Regarding  E. granulosus , a positive and significant correlation between host length and abundance was found for six (four ectoparasites, one mesoparasite, and one endoparasite) of the 14 taxa recorded, but prevalence was significantly correlated with host length only for the monogenean  Asthenocotyle  sp. Although the sample size for  A. nasutus  was limited, we compared richness, abundance, diversity and evenness at the infracommunity and component community levels. All of these variables were higher for  E. granulosus , but at the infracommunity level, abundance was higher for  A. nasutus . All the parasite taxa (except two) represent new host and geographical records.
