(2009): New and rare species of the pseudomorphine genera Sphallo- morpha Westwood, Adelotopus Hope, and Pseudomorpha Kirby mainly from far Northern Territory, Australia (Coleoptera, Carabidae, Pseudomorphinae). 12th supplement to the “Revision of the Pseudomorphinae of the Australian Region”. – Spixiana 32/2: 231-253 Five new species and one new subspecies of the pseudomorphine genera Sphallo- morpha Westwood, 1837 and Adelotopus Hope, 1834 from Australia are described: Sphallomorpha elseyi, S. laevior, S. triangularis, Adelotopus rufozonatus roperi, and A. frater, all from far Northern Territory, and S. aenigmatica from southern Western Australia. Records from various parts of Australia of a number of rare, ill docu- mented, or in the region so far unknown pseudomorphine species of the mentioned genera and of the genus Pseudomorpha Kirby, 1825 are also dealt with. All new spe- cies and subspecies are inserted in the respective general keys.
