K. saunion and K. eumenidarum also have the inner orbits with 
strong costae (Figs. 8,9,16,17), whereas the inner orbits of K. meg- 
alaspis are smooth (Figs. 1 2, 1 3). 1 consider the costate inner orbits to 
be a synapomorphy of Euperilampus + Krombeinius. As such 1 
interpret the smooth orbits of K. megalaspis as an autapomorphic 
reversal. A similar reversal in this character is indicated in the Eupe- 
rilampus cladogram (Darling 1983). 
There remain some difficulties in justifying the current composi- 
tion of the genus Krombeinius. The numerous characters separating
