This species is very closely related to Anacrocampsa frenata (Melichar), 

 from which it may be distinguished by characters mentioned in the 

 above description and key. The species is named in honor of Dr. 

 Wilhelm Wagner, of the Zoologisches Museum in Hamburg, who has 

 made notable contributions to homopterous taxonomy and whose 

 help and warm hospitality to the author and his wife made work in 

 Hamburg a pleasant task.
