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."
