Novel taxa of Cheilostomata Bryozoa discovered in the historical backlogs of the Iziko South African Museum.

Non-studied museum collections are hidden treasures-a source of information for various research fields. The novel taxa presented here were discovered during taxonomic examination of the backlogs of Bryozoa (Cheilostomata) from the Iziko South African Museum. We describe one new genus, Khulisa n. gen., and nine new species of bryozoans from South Africa. The new species are: Biflustra adenticulata n. sp., Aspidostoma sarcophagus n. sp., ?Micropora erecta n. sp., Trypostega richardi n. sp., Khulisa carolinae n. gen. et n. sp., Adeonella assegai n. sp., Hippomonavella lingulata n. sp., Phidolopora chakra n. sp. and Reteporella ilala n. sp. Three genera, Biflustra, Phidolopora and Triphyllozoon, are recorded for the first time from South Africa. This study highlights the importance of examining existing backlogged material lodged in museum collections.
