Anatomical Characters

The taxonomic status of Metrosideros queenslandica, and related species from New Guinea, is reassessed on the basis of fundamental morphological and anatomical characters and these species are found to be more closely allied to Tristanin sens. str. than to Metrosideros sens. lat. The current classification of this group of species as Metrosideros subg. Mearnsia sect. Adnatae J. W. Dawson is rejected and a new genus, Thaleropia, is described and the new combinations T. queeirslandica, T. iteophylla and T. hypargyrea made.

We propose a new generic classification of the African Restionaceae, tribe Restioneae (subfamily Restionoideae), based on the phylogeny and on extensive morphological data. The phylogeny is based on both plastid sequence data and morphological data. We delimit the genera to be monophyletic, to minimize the nomenclatural changes, and to maximize the ability to diagnose the genera. We recognize eight genera, one of which with nine subgenera, in the tribe. Of the currently accepted genera, only three need changes. We provide descriptions for all genera and subgenera, and include a key to them. In this paper we erect one new genus, Soroveta. redelimit Platycaulos and Restio, and reduce Calopsis and Ischyrolepis to synonomy under Restio. We list the species which we recognize under each genus, make 37 new combinations, propose eight new names, and also describe eight new species that belong in these genera.

Taxonomic Categories

A revised classification of the Holothyridae is presented. The family is restricted to archipelagoes from Melanesia to the Seychelles, with no known records from any continent. Evolution of holothyrid characters, phylogenetic relationships of the eight holothyrid genera and criteria for taxonomic categories in Holothyridae are discussed.Holothyrus braueri Thon, 1905, from the Seychelle Islands, is selected as the type species of a new genus, Sternothyrus. A new genus, Lindothyrus, is created for L. rubellus, sp. nov., from the western coast of New Caledonia, and L. elongatus, sp. nov., from Lord Howe Island, Australia. Indothyrus greeni, gen. et sp. nov., is described from Sri Lanka. Hammenius (Leiothyrus) Hammen, 1983 is raised to generic rank and Holothyrus nitidissimus Thorell, 1882 from the Fly River, and H. armatus Canestrini from Tamara Island (Aitape), both New Guinea, are included in this genus. The two previously known New Guinean genera, Thonius Lehtinen, 1981 and Hammenius Lehtinen, 1981, are redefined and relimited, and their type species are redescribed. Five new holothyrid taxa are described from New Guinea: Thonius mendi from the Strickland River, T. berlesei from an unknown locality, Hammenius fujuge iora from the Central district, Oro Province, H. grandjeani gressitti from Mt Bosavi, and H. insularis from the Louisiade Archipelago. Holothyrus Gervais, 1842 is restricted to two species from Mauritius only. A new genus, Haplothyrus, is created for the New Caledonian species H. expolitissimus Berlese, 1924 and for H. hyatti, sp. nov., from an unknown locality. Haplothyrus is characterised by the possession of a single female genital valve instead of four valves, as in all other genera of this suborder. The poorly described Seychellian species with no preserved material could not be revised.

AbstractThe generic classification of water striders belonging to the veliid subfamily Haloveliinae is discussed and revised and a key to the genera provided. A new genus of marine haloveliines, Haloveloides gen. n., is described. The type species of the new genus, H. papuensis (Esaki) comb. n., is redescribed and recorded from Papua New Guinea, the Bismarck Archipelago, and the Solomons. H. browni (Lansbury) comb. n. is redescribed and recorded from the same areas as the type species. Five new species are described in the genus: H. brevicornis sp. n. (the Moluccas, Sulawesi, Palawan), sundaensis sp. n. (Sunda shelf areas), danpolhemi sp. n. (Palawan), cornuta sp. n. (Luzon), and femoralis sp. n. (Palawan). The cladistic relationships and biogeography of the species are discussed.

Abstract A new procolophonid reptile from the Lower Triassic Arcadia Formation of Queensland, Australia is described on the basis of abundant cranial and postcranial remains. Eomurruna yurrgensis gen. & sp. nov. is the first parareptile from Australia, being represented by more than 40 specimens from which a detailed description of the osteology is made. The most characteristic feature of Eo. yurrgensis is the presence of six to eight blunted, monocuspid maxillary teeth that are circular in basal cross-section. The new Australian taxon features an interdigitated tooth-occlusion system that represents an intermediate functional stage between the primitive procolophonoid pattern, without apparent tooth-to-tooth contact, and the crown-to-crown occlusion system characteristic of the horned procolophonids. Its dentition suggests good capabilities of oral processing and shows instances of replacement. A phylogenetic analysis suggests that the new taxon occupies a relatively basal position within the Procolophonidae. The taxonomic status of the procolophonoid species ‘Owenetta’ kitchingorum and Saurodektes rogersorum from South Africa and ‘Eumetabolodon’ dongshengensis from China is reassessed. The new genus Youngetta gen. nov. and the new combinations Saurodektes kitchingorum  comb. nov. and Youngetta dongshengensis  comb. nov. are here proposed.

Wallace’S Line

K. Schumann's classification of Alpinia (Zingiberaceae), which subdivided the genus into five subgenera and 27 sections, was based, in the main, on the character of the secondary bracts (bracteoles). It is here proposed that the subgenera be reduced to two—Alpinia (7 sections and 10 subsections) and Dieramalpinia (4 sections and 2 subsections), and that the character of the labellum (petaloid or non-petaloid) be used as the main differentiating criterion. Such a classification shows the centre of distribution of subgen. Alpinia, in which the labellum is petaloid, to lie north of the equator; subgen. Dieramalpinia, in which the labellum is non-petaloid, or rarely so at the apex only, is now excluded from continental Asia and has its main concentration east of Wallace's line with its greatest number of species in New Guinea. Stigma types have been examined when possible and, so far, they substantiate the proposed classification.Keys to the subgenera, sections and subsections, together with distribution maps are provided. In Appendix 1 all published names in Alpinia are listed and annotated. Appendix 2 gives a key to the terminally-flowered genera of subfamily Alpineae; this is followed by five new names and six new combinations in Alpinia while A.cordylinoides is transferred to Riedelia.

AbstractThe generic classification of the Macropsini is reviewed, and five new genera and four new subgenera are erected: Macropsella n. gen., Macropsis (Neomacropsis) n. subgen, M. (Parapediopsis) n. subgen., Pedionis n. gen., P. (Thyia) n. subgen., Pediopsoides (Celopsis) n. subgen.; Reticopsis n. gen., Toropsis n. gen., and Varicopsella n. gen.. The following genus-group names are considered to be subgenera: Macropsidius Ribaut as a subgenus of Macropsis Lewis; Nanopsis Freytag, Kiamoncopsis Linnavuori and Sispocnis Anufriev as subgenera of Pediopsoides Matsumura; Parasitades Singh-Pruthi as a subgenus of Oncopsis Burmeister. Asmaropsis Linnavuori is synonymized with Hephathus Ribaut, Tsavopsis Linnavuori is synonymized with Macropsis (s.s.) Lewis, and Zinneca Amyot & Serville is synonymized with Oncopsis Burm. (s.s.).Three hundred and seventy-three macropsine species (including 59 unnamed species) are placed generically, with 73 new combinations. Twelve new species are described: Macropsella complicata (New Guinea), Macropsis citronella (Australia), M. gagnei (New Guinea), M. gressitti (New Guinea), Oncopsis enopis (Nepal), O. nepalensis (Nepal), O. tortosa (Nepal), Pedionis astrala (Philippines), P. contrasta (Hong Kong), P. venosa (Japan), Pediopsis femorata (Formosa), Varicopsella obtusa (Borneo). An index is provided to the 436 available names in the Macropsini, including four unplaced species from the Ethiopian region and 21 from the Australian region.Macropsine types in the B.P. Bishop Museum, Honolulu, the British Museum (Natural History), London, Hokkaido University, Sapporo, Japan, and the U.S. National Museum, Washington are illustrated and lectotypes are designated for Kirkaldy and Matsumura species. A neotype in the Canadian National Collection is designated for Zinneca flavidorsum Amyot & Serville.

Taxonomic Status

Abstract. The meridionally arranged rugosity, which is restricted to the Cretaceous globigerines, is given a superfamily taxonomic status. The globigerines displaying this type of ornamentation are placed in the Rugoglobigerinacea which is subdivided into two families the Rugoglobigerinidae and the Abathomphalidae. The Rugoglobigerinidae includes the forms having an umbilical primary aperture with a tegillum (Rugoglobigerina Brönnimann, Trinitella Brönnimann, and Plummerita Brönnimann). The Abathomphalidae includes the genera which have an umbilical–extraumbilical to spiro-umbilical primary aperture with a tegillum (Abathomphalus Bolli, Loeblich & Tappan, and Kassabella El-Nakhal), or a porticus (Meridionalla El-Nakhal, and Badriella n. gen.). Badriella is introduced as a new genus with B. mouradi n. sp. (= hypotype of Praeglobotruncana loeblichae Douglas) as a type species, to accommodate the meridionally costellate species with compressed chambers and umbilical–extraumbilical primary aperture, which were previously assigned to Praeglobotruncana Bermudez. The Rugoglobigerinacea may have evolved from a hedbergelline ancestor during the latest Albian via the development of the meridinally arranged rugosity.

A new genus for the Blue-and-yellow Tanager (Aves: Passeriformes):  a suggested adjustment to the classification of the Thraupidae

And Behavior

Recent DNA-based studies have found that the genus Thraupis, as traditionally defined, is polyphyletic, with the Blue-and-yellow Tanager (historically treated as Thraupis bonariensis) being sister to the Fawn-breasted Tanager (Pipraeidea melanonota). As a result, most subsequent classifications lumped both species under a single genus, Pipraeidea. Here I show that both species differ markedly in plumage, morphology, voice, and behavior, each of them being more similar to a distantly related species than to each other. As such, I argue that the treatment of the Blue-and-yellow Tanager in Pipraeidea creates an undiagnosable genus contrasting greatly with the generic limits commonly applied to the tanagers. To avoid this situation, I propose the recognition of a new genus, Remsenornis gen. nov., for the Blue-and-yellow Tanager.
