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.
Specimens of Burmagomphus asahinai Kosterin, Makbun and Dawwrueng, 2012 and Burmagomphus divaricatus Lieftinck, 1964 from SW and NE Cambodia show differences in the development of the light pattern. One male of the latter species has unusual posterior spinules on posterior hamuli. Two males of Orientogomphus minor(Laidlaw, 1931) from the same locality in NE Cambodia have substantial differences in the thoracic and abdominal pattern. NE Cambodian specimens of Gomphidia abbotti Williamson, 1907 and Lamelligomphus castor (Lieftinck, 1941) have minor differences from data on these species from literature. Caution is necessary when composing and using keys for identification of the mentioned genera of gomphids.
