California, and Florida. According to Hoffman (1930), "O turicata is found 

 in Mexico throughout about the same regions as [O. megnint]', that is to say, 

 it prefers the dry sections of the Central and Western Coast States but has 

 seldom been seen at altitudes of more than 2,000 meters. In the Valley of 

 Mexico it has been found in some instances on pigs imported from the in- 

 fested regions, but apparently cannot exist for any length of time in the 

 climate of the valley. The species rather prefers the less cold regions between 

 1,000 and 1,800 meters." (Translation.) 

 The type locality is Guanajuato, Mexico.
