ABSTRACT
Three new pseudomorphine carabid species of the genera Sphallomorpha Westwood, 1837 and
Adelotopus Hope, 1834 are described from Queensland, Australia: Sphallomorpha cognata and A.
leviusculus from south-eastern Queensland, and Adelotopus moffatti from central Queensland.
The new species are compared with their nearest relatives and introduced in the keys to the
respective genera. ¥ Coleoptera, Carabidae, Pseudomorphini, Sphallomorpha, Adelotopus, new
