The new species are compared with their nearest relatives and introduced in the keys to the respective genera. Coleoptera, Carabidae, Pseudomorphini, Sphallomorpha, Adelotopus, new species, Australia Within a sample of recently collected carabid Guinea, Solomon Islands, Java, and the beetles, received from Queensland Museum, Moluccas (Baehr 2009a), and one species of Brisbane, I detected, inter alia, three new species the genus Cryptocephalomorpha Ritsema, 1875 of the pseudomorphine genera Sphallomorpha even occurs in southern Africa, whereas most Westwood, 1837 and Adelotopus Hope, 1834, species of this small genus live in southern and from south-eastern and central Queensland south-eastern Asia (Baehr 2013). According to that are described in the present paper. present knowledge the tribe is most diverse, Pseudomorphini (or -inae, according to with respect to body shape and structure, in the opinion of the respective workers) is Australia, where six very differently shaped a moderately large tribe (or subfamily) of genera occur (Baehr 1992, 1997, 2002, 2005, Carabidae of outstanding shape and structure, 2006, 2008, 2009b, 2014). The American and has a very specialised biology. The tribe species have not yet been revised, and until mainly occurs in Australia and North and recently they were combined in a single South America, but a few species of the genera genus Pseudomorpha Kirby, 1825. Certainly Sphallomorpha Westwood, 1837 and Adelotopus they are far less diverse in their morphology Hope, 1834 have been recorded from New than the Australian Pseudomorphini. Baehr Memoirs of the Queensland Museum | Nature 2016 60 www.qm.qld.gov.au 29 Baehr, M. (1997) erected two subgenera of Pseudomorpha, single species of Paussotropus Waterhouse, namely Austropseudomorpha Baehr, 1997 for the 1877 and the single Australian species of few Australian species, and Notopseudomorpha Cryptocephalomorpha Ritsema, 1875 have not Baehr, 1997 for a few apparently more yet been recorded, but it is suggested that all plesiotypic South American species. However, pseudomorphine species live in connection more recently the genus Pseudomorpha has been with ants, a few even with termites (Baehr divided into several genera (Erwin & Geraci 1992, 1997). However, this is actually recorded 2008), and the subgenera erected by Baehr have from only a few species. The larviparous been raised to generic rank. When studied more reproduction of most genera likewise may satisfactorily in future, according to Erwin & Geraci (2008), the American species may nearly be related to the myrmecophilous habits of equal the number of Australian species. the larvae. Similarly, the increasing trend towards development of physogastric larvae Most pseudomorphine species are more in the higher evolved genera is regarded an or less depressed, possess depressed legs adaptation to that mode of life. and a reduced chaetotaxy. Depending on the genera to which they belong, their habitus is very similar to either water beetles of the METHODS families Dytiscidae or Hydrophilidae, or wood For the taxonomic treatment standard inhabiting Scolytidae or even Colydiidae. methods were used.
