Trigonopterus is a little-known genus of flightless tropical weevils. A survey in one locality, the Cyclops Mountains of West New Guinea, yielded 51 species, at least 48 of them undescribed. In this study, we show that mtDNA sequencing, or DNA barcoding, is an effective and useful tool for rapid discovery and identification of these species, most of them morphologically very difficult to distinguish even for expert taxonomists. The genus is hyperdiverse in New Guinea and different species occur on foliage and in the litter layer. Morphological characters for its diagnosis are provided. Despite their external similarity, the genetic divergence between the species is high (smallest interspecific divergence 16%, mean 20%). We show that Trigonopterus are locally hyperdiverse and genetically very strongly structured. Their potential for rapid local biodiversity assessment surveys in Melanesia is outlined (α-diversity); providing a regional perspective on Trigonopterus diversity and biogeography is the next challenge (β-diversity). © 2009 The Norwegian Academy of Science and Letters.

Arboreal snakes belonging to the pseudoxyrhophiine genus Stenophis inhabit Madagascar but despite their spectacular appearance, surprisingly little is known about their natural history and systematics. Nonetheless, a close phylogenetic affinity of the genera Stenophis and Lycodryas (the latter genus currently includes a single species from the Comoros) has been hypothesized. Based on recent molecular genetic data, however, the monophyly of Stenophis was challenged. This study aimed at a systematic analysis and taxonomic revision of the genera Stenophis and Lycodryas. On the basis of new molecular genetic and morphological data and analyses, we propose to accommodate these snakes in three monophyletic genera: Lycodryas, Phisalixella and Parastenophis, and to consider Stenophis as a junior synonym of Lycodryas. In the new generic arrangement, the genera can also be well distinguished by morphological characters. On the specific level, Phisalixella tulearensis is resurrected and indications of further, undescribed taxa are revealed. © 2010 The Authors.

Four new species of the leleupidiine genus Colasidia Basilewsky, 1954 are described from northern and north-western Borneo: Colasidia multispinosa and C. cordicollis from north-western Kalimantan, C. longipennis from Sarawak, and C. apicalis from Sabah. Colasidia brevicornis Baehr, 1988 which was so far known from Sarawak is now recorded from north-western Kalimantan. These are the first records of any leleupidiine species from Borneo outside of Sarawak and Sabah. A third record of C. mateui Baehr, 1997 is noted from Sabah. For the species of Co-lasidia recorded from the island of Borneo a key is provided. Source

A new lebiine carabid species, Anomotarus andamanicus, spec. nov., is described from Andaman Islands. The species is closely related to the widespread A. stig-mula Chaudoir and its allies. It is inserted in the most recent key to the Oriental-New Guinean Anomotarus. Source

New species and new records of the genus Anomotarus Chaudoir from Australia. 2nd supplement to the 'Revisions of the species of the genus Anomotarus Chaudoir'. Three additional new species of the lebiine genus Anomotarus Chaudoir, subgenus Anomotarus, and one species of the subgenus Nototarus Chaudoir are described from Australia and Tasmania: Anomotarus (s. str.) moorei from Australian Capital Territory, A. (s. str.) kimberleyensis from far northern Western Australia, A. (s. str.) sericipennis from Tasmania, and A (Nototarus) eyrensis from the Eyre Peninsula in South Australia. The new species are introduced in the most recent keys to the Australian species of the genus Anomotarus (s. 1.). New records of some rare or recently described species of the subgenera Anomotarus s. str., Nototarus Chaudoir, and Amplitarus Baehr are communicated. Source
