This genus is near Pevintlius Casey, of which several species, 

 all of termitophilous habit, are known from tropical America. 

 Lauella is distinct in having the antennae more robust, cylindrical 

 at base, and with only the last four joints flattened (much less 

 strongly than in any species of Perinthus), the eyes are not setose 

 and the anterior border of the lal)rum is very strongly excised at 

 middle. The legs of Perinthus are much less compressed.
