Survey of Odonata from Timor Island, with description of the female of Anax georgius (Odonata: Aeshnidae)

  • The survey is based on specimens held at Museums in Australia, Belgium and Germany. Altogether 487 specimens of 31 species from Timor were examined. These include: a recent collection from TimorLeste of 148 specimens (25 species) at the Australian Museum Sydney, an historic collection from West Timor consisting of 338 specimens (20 species) of the excollection Eugène Le Moult, stored at the Institut Royal des Sciences Naturelles de Belgique in Brussels, and a single specimen from West Timor of the Coll. Ris stored at the Senckenberg Naturmuseum Frankfurt, Germany. The following nine species are reported from Timor for the first time: Agriocnemis pygmaea, Austroallagma sagittiferum, Ischnura heterosticta, Xiphiagrion cyanomelas, Crocothemis servilia, Neurothemis ramburii, Orthetrum pruinosum cf. schneideri, Potamarcha congener and Zyxomma obtusum. The female of Anax georgius is described and illustrated. An illustrated key to the Anax species of the Lesser Sunda Islands is given and specimens from the Lesser Sunda Islands formerly identified as Anax gibbosulus are considered to be Anax panybeus. Some characters of the Orthetrum pruinosum taxa group of species, Tramea stenoloba and female Zyxomma obtusum are discussed. Figures of the male appendages and genital ligulae of Austroallagma sagittiferum, Aciagrion fragile and Xiphiagrion cyanomelas are provided, as well as figures of the male secondary genitalia, appendages and the penis of Trithemis lilacina and the male appendages of Epophthalmia vittigera. A preliminary checklist for Timor including 36 species is given.
