Kostenko AG, Mamkaev YuV 1990 (citation)- p 21, "Green convoluts possessing symbiotic algae and sagittocysts are isolated into a genus Simsagittifera [Symsagittifera] which is also characterized by a weakly pronounced ciliated antrum, ciliated vagina, and a thin sclerotized nozzle of bursa; the seminal vesicle does not have its own walls. Seven species are referred to the genus, they are: S. schultzei (O. Schmidt, 1852), S. roscoffensis (Graff, 1891), S. japonica (Kato, 1951), S. macnaei (Du Bois Reymond Marcus, 1957), S. psammophila (Beklemischev, 1957), S. bifoveolata (Mamkaev, 1971), S. nitidae (Yamasu, 1982). A detailed revision of S. psammophila is given. The comparative description of its reproductive apparatus contains new data on S. bifoveolata and S. schultzei."
