A biostratigraphic analysis of the bryozoan fauna of the Upper Paleozoic Copacabana Group in the Lake Titicaca region identified 15 genera and 45 species. Eight of the bryozoan species are new and 14 are presently not assignable to specific taxa. The new species are the cystoporates Fistulipora carrascoi, F. titicacaensis, F. multidiaphragma, the trepostomes Stenodiscus altiplana, Pseudobatostomella micropora, P. yanagidai, the cryptostome Rhombopora kawabei and fenestrate Septopora andeana. Biogeographically, among the 23 formerly described species, eight are endemic to the Andean province, seven are common to the Midcontinent province of North America and eight are found in the Tethyan province. The bryozoan faunas indicate a strong relationship with those of the Midcontinent province although considerable migration from the Tethyan realm presumably occurred.
