The monophyletic lineage Phytoptidae s. str. (Acariformes, Eriophyoidea) comprises ~75 described species in 17 genera associated with angiosperms. Since the last keys to the world genera of Eriophyoidea were published in 2003, five new phytoptid genera have been described: Neoprothrix (Reis & Navia 2014), Borassia Chetverikov, Craemer 2017, Solenoplatilobus Chetverikov & Craemer 2016, Solenocristus Chetverikov et al. 2018, and Calventer Chetverikov 2025. Here, we provide an updated generic key for the tribe Sierraphytoptini (Phytoptidae), describe a new genus Nothofagicola, propose a new combination N. nothofagalis n. comb. (Chetverikov et al. 2018) (transferred from Solenocristus), report the first findings of N. cf nothofagalis from Nothofagus pumilio and No. antarctica from Southern Chile and describe three new species of Nothofagicola collected in Central Chile from stems of three Nothofagus species (Fagales: Nothofagaceae): N. alpinae n. sp. from No. alpina, N. bicristata n. sp. from No. alessandrii, and N. licanteniensis n. sp. from No. glauca. We also provide a corrigendum to our previous paper and state that the correct accession numbers for mitogenomic sequences of Leipothrix aegopodiae and L. cf knautiae are OR268621 and OR268622, respectively (vice versa in the paper).
Chetverikov et al. (Sat,) studied this question.
