Taxonomic revision of New Guinea diving beetles of the Exocelina danae group, with the description of ten new species (Coleoptera, Dytiscidae, Copelatinae)

Bidessus migrator Sharp, 1882, so far assigned to Clypeodytes Régimbart, 1894, and widely distributed in Australia and New Guinea, is re-described. Based on morphological and molecular evidence, it is here transferred to Leiodytes Guignot, 1936. Bidessus loriae Régimbart, 1892 is found to be a junior subjective synonym of L. migrator. We describe the following new species: Leiodytes surianiae sp. nov. (eastern New Guinea, northeast coast of Queensland), and Leiodytes wattsi sp. nov. (southern New Guinea and Darwin area to northern Queensland). We delineate the species using characters such as male genital structure and beetle size, shape and color pattern. Mitochondrial Cox1 data for 27 individuals, representing all three Australasian species, were generated and revealed clusters congruent with the morphological evidence. In Australia Leiodytes only occurs in the tropical and subtropical northern part of the continent. None of the species is endemic to Australia. The species are mainly lentic, occurring in seasonal swamps, flooded meadows and pools of intermittent rivers and temporary creeks.

Four new Asian taxa are described and illustrated as part of a forthcoming taxonomic revision of the cultivated species of Begonia (Begoniaceae). The new species B. argenteomarginata (sect. Symbegonia) is described from Papua New Guinea. Two new species from section Petermannia are described: B. polilloensis from the Philippines and B. rachmatii from Sulawesi, Indonesia, both of which are unusual in having palmately compound leaf blades. A key is provided for these and a previously described species, B. oligandra, also with palmately compound leaf blades and in section Petermannia. The new subspecies B. brevirimosa subsp. exotica (sect. Petermannia) is described from the Central Range of Papua New Guinea and a brief history of its cultivation is presented.

Parsimony Analysis

The species of the former antlion subtribe Periclystina (Neuroptera: Myrmeleontidae) are revised. Prior to this work Periclystina comprised 10 genera and 63 species endemic to Australia (62 spp.) and New Guinea (1 sp.). In this work two former genera are synonymized and four new genera are proposed (for a total of 12 valid genera), and six former species are synonymized and 16 new species are proposed (for a total of 73 valid species). A parsimony analysis utilizing 62 morphological characters is used to infer phylogenetic relationships among all 73 species, and suitable outgroups. Based on the results of the phylogenetic analysis, the tribal and/or generic assignments of 55 (75%) of former Periclystina species are modified here. Periclystina and its two largest genera—Austrogymnocnemia and Glenoleon—were all recovered as polyphyletic in their former circumscriptions. Ten species—placed here in six genera: Anomaloplectron, Csiroleon, Fissuleon gen. nov., Franzenia, Fusoleon and Latileon gen. nov.—clustered phylogenetically with Acanthoplectron and are transferred to the tribe Acanthoplectrini. The remaining 63 species—placed in six additional genera: Austrogymnocnemia, Glenoleon, Megagonoleon gen. nov., Minyleon gen. nov., Periclystus and Riekoleon—form a monophyletic Periclystus genus group and are transferred to the tribe Dendroleontini. All 73 species are (re)described and illustrated. New identification keys are provided for the tribes of Dendroleontinae, for the Australian genera of Acanthoplectrini and Dendroleontini, and for each of the non-monotypic genera treated. In addition, five new lectotypes are designated and 35 new combinations are created.

We recognise 25 species from this area including three new species of robust tree palms from New Guinea: Hydriastele calcicola, H. lanata and H. wosimiensis. All species are described in full in the taxonomic treatment, with accompanying botanical illustrations, photographs, distribution maps and preliminary IUCN Red List Assessments.

Morphology and mitochondrial DNA sequence data are used to reassess the taxonomy of Australian diving beetles previously assigned to the genera Uvarus Guignot, 1939 and Gibbidessus Watts, 1978. Gibbidessus was described as a monotypic genus for Gibbidessus chipi Watts, 1978. The genus is significantly extended here. Based on molecular systematic evidence, Uvarus pictipes (Lea, 1899) is transferred to Gibbidessus. Gibbidessus chipi and Gibbidessus pictipescomb. nov. are redescribed, and six new species are described: Gibbiddessus atomussp. nov. (SW Australia, Northcliffe area) [the smallest epigean diving beetle in Australia], G. davidisp. nov. (SW Australia), G. drikdrikensissp. nov. (Victoria), G. kangarooensissp. nov. (SA Kangaroo Island), G. pederzaniisp. nov. (SW Australia, Nannup area), and G. rottnestensissp. nov. (SW Australia). Species are delineated using characters such as male genital structure and beetle size, shape and colour pattern. Mitochondrial Cox1 data for 27 individuals, representing five species, were generated, and revealed clusters congruent with the morphological evidence. Gibbidessus occur in southern Australia, with the centre of diversification in the isolated peat- and wetlands of SW Australia. All species occur in very shallow water of seasonal, exposed or half-shaded wetlands and flooded meadows.

Stepwise Discriminant Analysis

A program of stepwise discriminant analysis was used to distinguish seven groups of Papuan Rana believed, on ecological and behavioural characters, to constitute distinct species. Following the use of this method, four of these groups were associated with specific names in the literature, whereas three others could not be associated positively with any literature names and so are described as new species. Small samples from the eastern Indonesian islands and the east Melanesian islands made possible a comment on the identity of Rana occurring there. A synopsis of all species of Rana occurring in the area extending from the Indonesian islands of Timor and Seram to the Solomon Is is presented, and means of identifying species on the New Guinea mainland (by multivariate analysis or by dichotomous keys) are provided. A note on the chromosomes of some species is included.

A taxonomic revision of Didymochlaena (Didymochlaenaceae) from Asia and the Pacific region is conducted based on morphological and molecular evidence. Seven species are recognized, of which four are described as new and a new status is raised to a species from a variety. These four new species include D. fijiensis from Fiji, D. philippensis from the Philippines, D. punctata from Indonesia, Malaysia, and Thailand, and D. solomonensis from the Solomon Islands. The new status is D. oceanica from Papua New Guinea. Six of the seven species have all been erroneously treated as D. truncatula by earlier pteridologists. A key to the species is provided and descriptions of all species are given.

Three New Species

Nine new species groups of Exocelina Broun, 1886 from New Guinea are introduced with keys to their representatives. Four groups are monotypic and include three new species: the E. aipomek group, the E. koroba group: E. korobasp. nov., the E. mekilensis group: E. mekilensissp. nov., and the E. morobensis group: E. morobensissp. nov. The remaining five species groups include 18 species with 12 new species and one new subspecies: the E. bacchusi group: E. akamekusp. nov., E. oiwasp. nov., E. oksibilensissp. nov., and E. bacchusi herzogensisssp. nov.; the E. jaseminae group: E. asekisp. nov., E. kailakisp. nov., and E. pseudojaseminaesp. nov.; the E. larsoni group: E. warahulenensissp. nov.; the E. takime group: E. mianminensissp. nov.; and the E. warasera group: E. haiasp. nov., E. kobausp. nov., E. pulchellasp. nov., and E. waraserasp. nov. Diagnoses of five already described species of these groups are provided, as well as comparatives notes on all species. Exocelina santimontis (Balke, 1998) syn. nov. is a junior synonym of E. aipomek (Balke, 1998). Data on the distribution of the species are given, showing that most of the species of these groups occur in the Papua New Guinea.
