K. eumenidarum + K. saunion from K. mega/aspis question the 
inclusion of K. mega/aspis. A revised classification would create a 
monobasic new genus for Perilampus mega/aspis, and would allow 
Krombeinius to be defined by the synapomorphies of K. eumenic/a- 
rum + K. saunion. Recalling that the proposed synapomorphies of 
Krombeinius (structure of the labrum; host association) are not 
known for K. mega/aspis, it would not be surprising if this species 
were to be excluded at some later date. Clearly, more material and 
associated biological information are essential to re-evaluate the 
composition of Krombeinius, and any nomenclatural changes at 
this time would be premature.
