d="p-1">Crinoid faunas from the Lower Devonian of South America are poorly known. Two new taxa are described from the Emsian Icla Formation at Cerro Kochis in the Cochabamba Department: the rhodocrinitid, Lutocrinus boliviaensis n. gen. n. sp. and d-content genus-species" id="named-content-1">Griphocrinus pirovanoi n. sp. Two additional camerates are reported from the Emsian Belèn Formation of the Altiplano region in the La Paz Department, including d-content genus-species" id="named-content-2">Ctenocrinus branisai n. sp. and Boliviacrinus isaacsoni d="xref-ref-29-1" class="xref-bibr">McIntosh, 1988. In addition, a specimen of the blastoid, Pachyblastus dicki Bremier and Macurda, 1972, was recovered from the Altiplano region. These crinoids and material previously collected by Leonardo Branisa, including specimens of d-content genus-species" id="named-content-3">C. branisai n. sp., Apurocrinus sucrei d="xref-ref-28-1" class="xref-bibr">McIntosh, 1981, B. isaacsoni d="xref-ref-29-2" class="xref-bibr">McIntosh, 1988, and d-content genus-species" id="named-content-4">L. boliviaensis n. sp., are described and revised. The specimens give new insights into the Lower Devonian Malvinokaffric Realm of Bolivia, a relatively new frontier in crinoid paleontology.
