    [Ichthyology • 2016] Three New Stingrays (Myliobatiformes: Dasyatidae) from the Indo–West Pacific; Himantura australis, Taeniura lessoni & Telatrygon biasa

     Taeniura lessoni  
    Last, White & Naylor, 2016  


    Abstract

    Three undescribed stingrays were discovered as part of a broader revision of the family Dasyatidae that formed part of the Chondrichthyan Tree of Life project. This research forms part of a sequence of papers on rays aimed at describing unnamed species for inclusion in a multi-authored guide to rays of the world. The first part of this series focused on a redefinition of genera of the family Dasyatidae. The new Indo–West Pacific taxa are represented by separate genera from three dasyatid subfamilies: Himantura australis sp. nov. (northern Australia and Papua New Guinea), Taeniura lessoni sp. nov. (Melanesia) and Telatrygon biasa sp. nov. (Indo–Malay Archipelago).

    Himantura australis sp. nov., which belongs to a complex of four closely related reticulate whiprays, differs subtly from its congeners in coloration, morphometrics and distribution. Taeniura lessoni sp. nov. is the second species in a genus containing the widely-distributed T. lymma, which is possibly the most abundant stingray in shallow coral-reef habitats of the Indo–Pacific, with the new species apparently restricted to Melanesia. Taeniura lessoni sp. nov. is distinguishable by the absence of a distinctive pair of vivid blue longitudinal stripes on the dorsolateral edges of the tail which is one of the most distinctive features of T. lymma. Telatrygon biasa sp. nov. belongs to a small, recently designated genus of stingrays represented by four species in the tropical Indo-West Pacific. Telatrygon biasa sp. nov. differs from these species in morphometrics. The new species differs markedly from T. zugei in its NADH2 sequence. Telatrygon crozieri is resurrected as a valid northern Indian Ocean representative of the T. zugei complex.

    [Botany • 2015] Impatiens kingdon-wardii • A New Species from Mt. Victoria (Natma Taung), northwestern Myanmar

    Impatiens kingdon-wardii 
    Nob. Tanaka & T. Sugaw. 


    Abstract
    A new species, Impatiens kingdon-wardii Nob. Tanaka & T. Sugaw. (Balsaminaceae), is described and illustrated from Mt. Victoria (Natma Taung), northwestern Myanmar. This species is distinguished from any other species by the pink orbicular, densely pubescent lateral sepals, appearance of which is like two ears of the mouse, and upper lobes of lateral united petals with hairy club-shaped protuberance.

    [Herpetology • 2017] Extended Molecular Phylogenetics and Revised Systematics of Malagasy Scincine Lizards

    Fig. 1. Phylogeny of Malagasy scincine lizards, based on a 50% majority rule consensus tree inferred through Bayesian analysis of 12 concatenated loci (3 mtDNA, 9 nDNA) comprising 8060 bp (outgroups not shown). Node values represent posterior probability from BI and bootstrap support from ML and MP analyses, respectively (see Fig. SM2). Bootstrap values under 70 are not displayed and denoted with a dash. Dashed branches indicate the tentative placement of taxa with multiple missing data (as inferred with a second Bayesian analysis) and with posterior probabilities in parentheses. Clades characterized by quadrupedal taxa are highlighted in color, while the clades consisting of limb-reduced fossorial taxa are highlighted in grey. For Grandidierina fierinensisParacontias mahamavo and P. ampijoroensis, two individuals each were included in the analyses (see Table SM1) that showed very low intraspecific genetic divergence, and were collapsed in the tree to display all terminal taxa at the species level. The three candidate species of Amphiglossus are named according to provisional names used in Glaw and Vences (2007).

     Highlights
    • A new phylogenetic hypothesis for Malagasy scincines based on an extended multilocus dataset.
    • Phenotypic comparisons corroborate divergent molecular patterns of evolution.
    • Three separate clades of Amphiglossus, characterized by different degrees of body elongation.
    • Amphiglossus redefined into three different genera based on combined molecular and morphological findings.

    Abstract
    Among the endemic biota of Madagascar, skinks are a diverse radiation of lizards that exhibit a striking ecomorphological variation, and could provide an interesting system to study body-form evolution in squamate reptiles. We provide a new phylogenetic hypothesis for Malagasy skinks of the subfamily Scincinae based on an extended molecular dataset comprising 8060 bp from three mitochondrial and nine nuclear loci. Our analysis also maximizes taxon sampling of the genus Amphiglossus by including 16 out of 25 nominal species. Additionally, we examined whether the molecular phylogenetic patterns coincide with morphological differentiation in the species currently assigned to this genus. Various methods of inference recover a mostly strongly supported phylogeny with three main clades of Amphiglossus. However, relationships among these three clades and the limb-reduced genera GrandidierinaVoeltzkowia and Pygomeles remain uncertain, mainly based on maximum likelihood and maximum parsimony estimates. Supported by a variety of morphological differences (predominantly related to the degree of body elongation), but considering the remaining phylogenetic uncertainty, we propose a redefinition of Amphiglossus into three different genera (Amphiglossus sensu strictoFlexiseps new genus, and Brachyseps new genus) to remove the non-monophyly of Amphiglossus sensu lato and to facilitate future studies on this fascinating group of lizards.

    Abstract
    The Myanmar snub-nosed monkey Rhinopithecus strykeri was discovered in 2010 on the western slopes of the Gaoligong Mountains in the Irrawaddy River basin in Myanmar and subsequently in the same river basin in China, in 2011. Based on 2 years of surveying the remote and little disturbed forest of the Gaoligong Mountains National Nature Reserve in China, with outline transect sampling and infrared camera monitoring, a breeding group comprising > 70 individuals was found on the eastern slopes of the Gaoligong Mountains in the Salween River Basin. Given the Critically Endangered status of this primate (a total of < 950 individuals are estimated to remain in the wild), efforts to protect the relatively undisturbed habitat of this newly discovered population and to prevent hunting are essential for the long-term survival of this species.

    Argostemma laotica 
    Lanorsavanh & Chantar.  


    Abstract

    Argostemma laotica, a new species from Laos, is described and illustrated. The species appears most similar to A. concinnum but differs in having pubescent stem, corolla and ovaries, oblique leaf base, shorter pedicel and smaller anthers which a dehiscence by an apical pore. The conservation status of this new species is vulnerable (VU D2).

    Keywords: Argostemma laotica, Rubiaceae, Eudicots



    Argostemma laotica is similar to A. concinnum Hemsley (1895: t. 2380) in perennial herb with tuber, acute leaf apex, terminal inflorescence, 5-merous flower, triangular calyx lobes, star-shped flower and capitate stigma, but differs in having pubescent stem (vs. glabrous), leaf base oblique (vs. acute or attenuate), corolla and ovaries pubescent (vs. glabrous), and shorter pedicels of 6–7 mm long (vs. 10–20 mm long) and smaller anthers of 2.2–2.5 mm long (vs. 5–6.5 mm long), which a dehiscence by an apical pore. 

     Phenology:— Flowering in July.

     Etymology:— The specific epithet refers to the country in which the specimen was collected.

    Distribution and ecology:— Endemic to Laos and only known from the type locality in Xiangkhoang, growing on wet rock, along river, elevation ca. 200 m.

    Etymology: Gr. Pardos m. – leopard + oros, -eos n. mountain. Named after the type locality of Tierberg Nature Reserve (Tierberg meaning tiger (= leopard) mountain).

    Distribution, phenology and biology: Known only from the type locality. Collected in February (Table 1). Little is known of the biology. Tierberg Nature Reserve is a small conservation area comprised almost entirely of a large rocky hill on the outskirts of Keimoes, a small town located on the north banks of the Gariep (= Orange) River which provides water for agricultural activities in what is otherwise an arid area of the country. Vegetation is sparse and dominated by succulents such as aloes (Figs 13–14). The flies were found resting on hard-baked ground and stones.
