Habitat: Ecological data are available for all but five of the 252 
specimens of this species seen. Of these, 225 specimens were 
collected in carrion traps or at carrion (six collections), twelve from 
fungi on logs and stumps (one collection), eight under bark of 
Eucalyptus and Nothofagus logs (one collection), three in tussocks 
(one collection), and one among fallen leaves (presumably loose 
ground litter). Most of the specimens were collected in Nothofagus 
forest, and in general Glypholoma rotundulum seems to occur in 
habitats similar to those of G. pustuliferum, but nothing is known 
about the feeding habits of this species, either. These beetles seem to 
be notably cold-adapted. The largest collection (183 specimens) was 
taken in carrion traps set in snow-covered ground (S. B. Peck, pers. 
comm.), across which the flightless beetles must have walked. 
Wing polymorphism: All specimens examined are brachypterous 
except the three from Mt. Buffalo, the northernmost recorded 
locality for the species. One of these specimens (d) has fully- 
developed wings and the other two ( d9 ) have wings sharply 
reduced beyond the costal hinge. 
Etymology: The species name rotundulum (diminutive of rotun- 
dum, round) refers to the great convexity and small body size of the 
members of this species. 
Discussion 
We believe that the five species here included in Glypholoma form 
a monophyletic group (in the strict, Hennigian sense) which can be 
defined on the basis of these characters which we presume to be 
uniquely derived or synapomorphic within Omaliinae: excavate
