Checklist of the Odonata (Insecta) of Sundaland and Wallacea (Malaysia, Singapore, Brunei, Indonesia and Timor Leste).

A checklist, based on a database containing published data, of the Odonata (dragonflies and damselflies) occurring in Sundaland and Wallacea is presented. The presence of (sub)species is indicated for eight main regions (Singapore & Peninsular Malaysia, South China Sea (islands in the South China Sea that are not sensibly treated as satellites of larger landmasses), Borneo, Sumatra, Java & Bali, Lesser Sunda, Sulawesi, Moluccas), 22 subregions and 80 smaller islands and island groups. In total 743 full species are recorded from the entire area with 549 species known from Sundaland and 270 from Wallacea.

Description of the larva of Brachygonia oculata (Brauer, 1878) (Odonata: Libellulidae) with notes on rearing technique.

The larva of the genus Brachygonia Kirby, 1889 is described and illustrated for the first time based on the larvae of Brachygonia oculata (Brauer, 1878) discovered and successfully reared in Singapore. Compared to known larvae from genera in the rather heterogeneous subfamily Brachydiplacinae, B. oculata is most similar to species from the genus Brachydiplax Brauer, 1868 after comparison is made with the larva of Brachydiplax farinosa Krüger, 1902.

A new species of Podolestes Selys, 1862 from peat swamp forest in Sarawak (Odonata: Zygoptera: Argiolestidae).

Podolestes parvus sp. nov. is described and illustrated from both sexes from Sarawak, Malaysian Borneo (holotype male Maludam National Park, Betong Division, Sarawak, 10 vii 2012, deposited in RMNH).

sp. nov., a new dragonfly species from Thailand (Odonata: Anisoptera: Aeshnidae).

Oligoaeschna sirindhornae sp. nov. is described from a male from Sakaerat Silvicultural Research Station, Nakhon Ratchasima Province in Thailand.

Revision of the Genus Selys in Borneo, including gene trees and a two marker molecular phylogeny (Odonata: Anisoptera: Gomphidae).

The Bornean members of the genus Leptogomphus Selys are revised. Two new species are described: Leptogomphus schieli sp. nov.
