Siricidae. Taylor (1967) developed a laboratory culture in Tasmania on Sirex noctilio
from field collected cinctipes adults shipped from Calif. Additional material was
imported from Ariz, and N. Mex., and cinctipes has been released and established in
Tasmania as a parasite of Sirex noctilio (Taylor, 1977, p. 430). S. noctilio does not occur
within the natural range of Schlettererius cinctipes.
