REVISION OF THE GENUS HABUTARUS BALL & HILCHIE FROM THE AUSTRALIAN REGION (INSECTA, COLEOPTERA, CARABIDAE, LEBIINAE) MARTIN BAEHR Baehr, M. 2008 04 30: Revision of the genus Habutarns Ball & Hilchie from the Australian region (Insecta, Coleoptera, Arabidac, Lcbinae). Memoirs of the Queensland Museum 52(2): 13^8. Brisbane. ISSN 0079-8835. As a third part of a general revision of the Oriental-Australian species formerly assigned to the genus Anomotarus Chaudoir (s.L), the genus Habutarus Ball & Hilchie is revised. Nototarus crassiceps (Macleay) and N. morasus Sloane from Australia, and N. pilosus Baehr from New Guinea are herein transferred from the genus Nototarus Chaudoir of the subtribe Calleidina to the genus Habutarus Ball & Hilchie of the sublribe Apcnina. A new subgenus, Setitarus subgen. nov. is erected for N. pilosus Baehr. For nomenclatural stability, a lectotype is designated for Nototarus crassiceps (Macleay). The following new species Habutarus are described: H. abboti, H. calderi, H. canaliculatus, H. chitlagoensis. H. convexipennis, H. demarzi. H. eungellae, H. iridipennis, H. kirramae, H. laticeps, H. monteithi, H. nitidicollis, H. opacipennis. H. parviceps, H. punctatipennis, H rugosipennis and H. weiri from Australia, and //. madang and H. wau from New Guinea. Due to its close relationships to the African-Oriental genus Cymindoidea Caslelnau, the genus Habutanis represents an Oriental faunal clement that immigrated into the Australian Region only after the Australian plate came in contact with the South Asian insular arc some 10 mya. The genus subsequently underwent a period of rapid speciation, mainly in the montane rainforests along the ea.st coast of Queensland. Some species, however, also occur in more open forests in northern Queensland and the Top End of the Northern Territory. Most species arc very closely related which suggests very recent, probably Pleistocene speciation events. ¥ Coleoptera, Carabidae, Lebiinae, Habutants sp. now, Setitarus subgen. now, Australia.

The lebiine subgenus Habutarus was proposed Lorenz (1998, 2005) included as subgenus of by Ball & Hilchie (1983) for the unique New Anomotarus Chaudoir. This seems justified in Guinean species Nototarus papua Darlington. view of the close relationships of both taxa and the Based on the structure of the male and female fact that some characters fonnerly used to separate genitalia and of the mouthparts, the authors the two genera are variable and hence, it is only recognised that this species could not remain the presence or absence of the mental tooth that in the genus Nototarus Chaudoir of the lebiine differentiates the two (see Baehr, 2005b; 2006). subtribe Calleidina, but belonged to the sublribe The apenine genus Cymindoidea s. sir, ranges Apenina, closely related to the Oriental-African through large parts of the Ethiopian and Oriental genus Cymindoidea Castelnau.
