Florida: Welaka (Conservation Reserve, University 
of Florida), August 12, 1954, J. D. H., 1 $ (holotype), 
from dead fallen branches of Turkey Oak ( Quercus laevis ) , 
in open sandy woods. 
This is the second species of the genus Tylothrips, which 
the writer erected in 1937 for a Peruvian species that 
came from dead branches and leaves. The two are almost 
identical in color and general appearance and could easily 
be confused with each other.
