contents	Protocirrineris (Polychaeta:Cirratulidae) in South Africa and description of two new species Rodolfo Elías María-Andrea Saracho-Bottero Carol-Anne Simon Biología Taxonomy new species Cirratulidae Protocirrineris misidentifications Introduction: The knowledge of polychaetes in the subtropical region of Africa benefited from the activity of J. Day. However, 50 years after the publication of his Monograph of the Polychaeta of southern Africa, it is necessary to reconsider the identity of the Cirratulidae due to changes in the diagnostic characters and new approaches to the taxonomy of the group to corroborate the status of cosmopolitan species in this region. Objective: We hypothesize that biodiversity of multitentacular Cirratulidae polychaetes has been significantly underestimated in southern Africa. Methods: The present work analyzes material deposited in the Iziko museum, as well as recently collected specimens, using scanning electron microscope to identify them. Results: The material corresponds to two new species belonging to the genus Protocirrineris. Protocirrineris strandloperarum sp. nov. is characterized by having the tentacular filaments between the chaetigers 5 to 10-12 and the first pair of branchiae from chaetiger 7, and P. magalhaesi sp. nov. is characterized by having tentacular filaments between chaetigers 4-8 and the first pair of branchiae from chaetigers 2 or 3. Descriptions of these species, with light and scanning electron microscope images, are given. Schematic drawings of the two new species are shown comparatively with diagnostic characters. Conclusions: The use of new techniques enables discovery of new taxonomic characters and two new species of the genus. The diversity of Cirratulidae polychaetes is underestimated also in the subtropical and tropical regions of Africa. 2019 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44965909006 https://www.redalyc.org/journal/449/44965909006/ https://www.redalyc.org/journal/449/44965909006/html/ https://www.redalyc.org/journal/449/44965909006/44965909006.epub https://www.redalyc.org/journal/449/44965909006/movil DOI 10.15517/RBT.V67IS5.38931 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.5 Vol.67
