Pogonomyza gleniensis differs from P. spinosissima in the chaetotaxy of 

 the legs, and from P. proboscidalis in the coloration of the wings and calyp- 

 trae. In appearance and form, the abdomen is very similar to that of 

 Hylemyia laevis Stein. This species differs, however, in possessing discal 

 bristles on terga 3, 4, and 5, as well as the usual marginal bristles.
