In the second half of February 2014, Odonata were searched for nine days on Bali andfour days on Lombok, the western Lesser Sundas, Indonesia. One species, Orthetrum chrysishas been for the first time recorded for Bali and six species, Nosostictaemphyla, Idionyx murcia, Brachydiplax chalybea, Agrionoptera insignis, Neurothemisramburii, Rhyothemis phyllishave been for the first time recorded for Lombok. The previous lit-erature concerning the two islands is analysed. To the moment, 55 Odonata species (3 unidentified) are known for Bali and 39 for Lombok, although the actual faunas of both islands are supposed to be equally rich, and further studies on Lombok are necessary. Odonata faunas of Bali and Lombok mirror each other in respect of high shares,29 and 23%, of Odonata species ranging to the west and east of the two islands, respectively. Efficiency of Lombok Strait as a biogeographical boundary was estimated as high as 0.6, so Wallace Line is of importance for Odonata. Some diagnostic characters of N. emphyla, N. ramburii, R. phyllis phyllisand Procordulia sambawanaand a taxo-nomical situation around Prodasineura autumnalisand P. humeralis, which is not justified biogeographically, are discussed. Short notes on habitats and assemblages of Odonata are added.
We identified a high diversity in the net-winged beetles of the genus Cautires in Peninsular Malaysia. Fourteen new species are described: Cautires alexae sp. nov., C. andujari sp. nov., C. arribasae sp. nov., C. berembanensis sp. nov., C. campestris sp. nov., C. communis sp. nov., C. jasarensis sp. nov., C. katarinae sp. nov., C. kirstenae sp. nov., C. kotatinggensis sp. nov., C. linardi sp. nov., C. maseki sp. nov., C. pahangensis sp. nov. and C. renatae sp. nov. Seven previously described species are discussed, illustrated and differential diagnoses provided; all species are keyed. The Cautires species differ in a limited number of diagnostic characters, namely in the shape of male antennae, the relative size of eyes and in the shape of the male genitalia. The females are difficult to assign to a conspecific male due to high intraspecific variability. The characteristically low dispersal propensity of net-winged beetles lead to the evolution of the unique fauna in the Malay mountains and despite an extensive study of the type material we recorded only a single species of Cautires occurring simultaneously in Sumatra. We suggest that the Malay mountain fauna is highly endemic and evolved in situ.
