Follow up studies of the taxonomic relationship of these and other closely related genera in a genus group {Boliviela, Dicodia Nielson, Gracilidia Nielson, Tinocripus Nielson and Paralidia) supported recognition of four new genera: Collasuyusana, type-species, Boliviela retrorsa Nielson; Ventrolidia, type-species, Boliviela orthaNielson; Carinoscapula, type-species, Boliviela bispinata Nielson; and Armaturolidia, type-species, Paralidia denticulata Nielson. Five species are removed from Boliviela and designated new combinations: Ventrolidia ortha (DeLong), Ventrolidia paraortha(Nielson), Carinoscapula sarcula (Nielson), Carinoscapula bispinosa (Nielson) and Collasuyusana retrorsa (Nielson). Two species are removed from Paralidia and designated new combinations: Armaturolidia spinata (Nielson) and Armaturolidia denticulata (Nielson). Godoyana Nielson, type-species Godoy-ana laselvensis Nielson is suppressed as a junior synonym of Coelidia German This species is assigned to Coelidia and designated new combination: Coelidia laselvensis (Nielson). A key to 9 genera in the genus group is also presented. A data matrix table of diagnostic generic characters is given for the Boliviela genus group. Thirty-nine new species are described and illustrated with a revised key to species in the following genera: Armaturolidia ordocrista, sp. nov.; Boliviela cucurbita, sp. nov.; B. caverna, sp. nov.; B. biungulata, sp. nov.; Coelidia costaricensis, sp. nov.; C. angulata, sp. nov.; Collasuyusanapicea, sp. nov.; C. diversa, sp. nov.; C. collaris, sp. nov.; C. spenceri, sp. nov.; C. recurvata,sp. nov.; C. bifurcata, sp. nov.; C. lanceolata, sp. nov.; Dialodia bispinata, sp. nov., D. longilobata, sp. nov., D. brevilobata, sp. nov., D. aviculobata, sp. nov.; D. brevisetacea, sp. nov.; D. bilongata, sp. nov.; Dicodia recurvata, sp. nov.; Evansolidia set-acea, sp. nov.; E. inca, sp. nov.; E. unilamina, sp. nov.; E. episetacea, sp. nov.; E. recurvata, sp. nov.; E. gracilitas, sp. nov.; E. lyrata, sp. nov.; E. inflata, sp. nov.; E. fletcheri, sp. nov.; Gracilidia minuta, sp. nov.; G. longiuscula,sp. nov.; G. biflangata, sp. nov.; G. tubercula, sp. nov.; G. uniflangata, sp. nov.; G membrana, sp. nov.; Omanolidia inflata, sp. nov.; Spinolidia moweri, sp. nov.; Tinocripus angustus, sp. nov. and T. sinuatus, sp. nov. Taxonomic review and new distribution records are also given.
