Pygmaeothrips Karny

The only species in this genus, P. angusticeps, has been found widely in tropical countries, and as a result of the polymorphism it exhibits it has been described under several different names. A few specimens have been seen from dead wood at several sites across northern Australia (Fig. 38).
