Supplement to the “Revisions of the species of the subgenus Anomotarus Chaudoir s. str.” (Coleo- ptera, Carabidae, Lebiinae). Spixiana 34 (1): 21-32. As a supplement to the revisions of the species of the genus Anomotarus Chaudoir s. str. from the Oriental and Papuan regions, and from Australia, four new species are described: A. mourae and A. toombae from Queensland, Australia, A. jakli from Tanimbar Islands, and A. scriptus from Thailand. Also new records of some rare or little known species are communicated. The new species are inserted in the most recent keys to the Oriental and Australian Anomotarus. Martin Baehr, Zoologische Staatssammlung München, Münchhausenstr. 21, 81247 München, Germany; e-mail: [email protected] Introduction The genus Anomotarus Chaudoir belongs to the lebiine subtribe Calleidini and consists of more or less While visiting recently a number of Australian elongate, usually ground living carabid beetles which collections and checking the unidentified carabid are characterized by more or less securiform labial material, I sorted out specimens of a number of rare palpi, rather projected eyes, usually rather swollen or undescribed species of the subgenus Anomotarus orbits, and denticulate tarsal claws.
