It is possible that instead of Exorista caesar Aldrich this species 

 may be the same as E. nigripalpis Townsend. In any case nigripalpis 

 is preoccupied by Exorista nigripalpis Macquart, 1846.

 row of eight bristles, extending from on a level with base of third 

 antennal segment to two reclinate preverticals; facial ridge bristly on
