The genus Lestes (Odonata: Lestidae) Leach, 1815, in Surinam

The species of Lestes from Surinam are treated. L. basidens spec. nov. (♂ holotype: Distr. Nickerie, Sipaliwini, near airstrip), L. curvatus spec. nov. (♂ holotype: Distr. Suriname, Coropina creek, Republiek), L. edentatus spec. nov. (♂ holotype: Distr. Marowijne, Nassau mountain range) and L. trichonus spec. nov. (♀ holotype: Distr. Nickerie, Sipaliwini, near airstrip) are described and illustrated. The types are deposited in the National Museum of Natural History, Leiden. L. mediorufus Calvert and L. tenuatus Rambur are illustrated and a lectotype for the latter species is designated. The holotype of L. sublatus Hagen in Selys is redescribed and illustrated. L. forficula Rambur, known from the surrounding countries of Surinam, is also illustrated. A key to the Surinam species of Lestes is provided.

The Australian Gomphidae (Odonata)

The Australian Gomphidae belong in the subfamilies Ictinogomphinae and Gomphinae. The three ictinogomphine species are placed in the widespread genus Ictinogomphus Cowley: I. australis (Selys), I. dobsoni (Watson), and a new species, I. paulini. The gomphine genera are endemic, and fall into two groups, the Hemigomphus and Austrogomphus groups. The first contains Hemigomphus Selys [H. comitatus (Tillyard), H. gouldii (Selys), H. heteroclytus Selys (type species), plus four new species, H. atratus, H. cooloola, H. magela, H. theischingeri], Armagomphus Carle [type- and only species A. armiger (Tillyard)] and the new genus Odontogomphus, comprising two new species, O. donnellyi (type species) and O. longipositor. The second includes Antipodogomphus Fraser [A. acolythus (Martin), A. hodgkini Watson, A. neophytus Fraser, A. proselythus (Martin) (type species) plus two new species: A. dentosus, A. edentulus], and Austrogomphus Selys, divided into five subgenera, Austrogomphus Selys [A. angeli Tillyard, A. arbustorum Tillyard, A. australis Dale in Selys, A. collaris Hagen in Selys, A. cornutus, sp. nov., A. doddi Tillyard, A. guerini (Rambur) (type species), A. mjobergi Sjöstedt, A. ochraceus (Selys) and A. pusillus Sjöstedt], Austroepigomphus Fraser, stat. nov. [A. melaleucae Tillyard, A. praeruptus (Selys) (type species)], plus three new subgenera, Pleiogomphus [A. amphiclitus (Selys) (type species), A. bifurcatus Tillyard, A. prasinus Tillyard, plus a new species, A. divaricatus], Xerogomphus [A. gordoni Watson, A. turneri Martin (type species)], and Zephyrogomphus [type- and only species A. lateralis (Selys)]. Lectotypes are designated for Hemigomphus heteroclytus Selys and Antipodogomphus neophytus Fraser, and neotypes for Austrogomphus gouldii Selys and Austrogomphus collaris Hagen in Selys. Data are provided on the larvae of endemic genera, and on the distributions and habitats of species, all of which are keyed.

The Australian Protoneurinae (Odonata)

The synonymy of Notoneura Tillyard with Nososticta Hagen in Selys is established. Six new species of Nososticta are described, N. baroalba, N. koongarra, N. koolpinyah and N. taracurnbi from the northern parts of the Northern Territory, N. liveringa from the north-west of the Northern Territory and the Kimberley region of Western Australia, and N. kalumburu from the Kimberley region. The five other known Australian species are redescribed, and the 11 species are compared and keyed.

NEW SPECIES OF AUSTRALIAN LESTIDAE (ODONATA)

AbstractThree new species of Australian Lestidae, Austrolestes aleison, Austrolestes minjerriba, and Indolestes obiri, are described, and the adults of the 14 known species of Australian lestids are keyed. Lectotypes are designated for Lestes psyche Hagen in Selys and Lestes leda Selys. Austrolestes albicauda tindalei Tillyard is newly placed in synonymy with Indolestes alleni (Tillyard).

Notes on the Selysian Types of Epigomphus Paludosus Hagen in Selys

I am indebted to the authorities in charge of the Brussels Museum and in particular to Dr. Antoine Ball for their courtesy and kind co-operation whereby I have been able to make a re-examination of the supposed types of Epigomphus paludosus Hagen in Selys. The species was first described in the Syn. Gomphines, and the type, which was said to be in Dr. Hagen's collection, was given as from Brazil. Kirby, in his Cat. Odonata, 1890, p. 71, ascribed the species to Selys but the Mon. Gomphines was written in collaboration with Dr. Hagen, and the Synopsis was a resume of this work by the two authors, as is stated in the preface to the latter work: thus the correct course to adopt in the present case is to give the authorship to Hagen in Selys . It is not certain whether the Hagenian types went eventually into the Selysian collection or were deposited in the Konigsberg Museum but I believe into the former prior to Hagen emigrating to the United States.
