It is rather curious, although at present insignificant, that the 

 abnormality of having a cubito-anal cross-vein situated proximad 

 to the level of the first antenodal should be more frequent on the 

 left side in both the front and the hind wings. 



The specific name proposed, percuhitale, is in allusion to the 

 unusual numbers of cubito-anal cross-veins.
