We describe nine new species of microhylid frogs in the genera Austrochaperina, Cophixalus, Copiula, Hylophorbus, Oreophryne and Xenorhina from the Muller Range in western Papua New Guinea. Each of the new species differs from congeners by a suite of morphological and acoustic characters. The discovery of so many new species during a survey of short duration (three weeks) and limited geographical coverage suggests that many additional species remain to be detected within this poorly known mountainous region. © 2014 Senckenberg Gesellschaft für Naturforschung.

Lithonecrus papuanus Nieves-Aldrey & Butterill, a new genus and species of inquiline oak gall wasps (Hymenoptera: Cynipidae: Synergini), is described from material reared from galls on Lithocarpus celebicus (Miq.) Rehd., collected in Papua New Guinea. The new genus and species is the first record of a cynipid from Papua New Guinea and the whole Oceanian biogeographic region, and represents the easternmost oriental record of a cynipid wasp (Hymenoptera: Cynip-idae). The new genus is similar to Saphonecrus Dalla Torre & Kieffer, and to the recently described Lithosaphonecrus Tang, Melika & Bozsó, but differs from these genera in several important diagnostic characters. Taxonomic affinities and differences with related genera and species and biogeographical implications are discussed. Copyright © 2014 Magnolia Press. Source

The north slopes of Mt. Wilhelm, the highest peak in Papua New Guinea, support a complete elevational gradient of relatively undisturbed rainforest, from 200 m to the tree line at 3,700 m. Based on field work in 2010 and 2012 over the Mt. Wilhelm elevational gradient, we report novel distribution data for 43 species, including geographic and elevational range extensions, demographic data, and new records of species poorly known in New Guinea. © 2014 British Ornithologists' Club.

Species of the cixiid tribe Bennini are characterized by a pair of lateral rod-like appendages at the base of the abdomen which are present in both sexes. Hitherto, 22 Bennini species have been described in the genera Benna, Bennaria and Celebenna from throughout Southeast Asia, two of which occur in New Guinea. Recent field studies carried out in native forest ecosystems in Madang Province, East Papua New Guinea, provide evidence that the number of Bennini species is - as in many other insect taxa - higher than previously assumed. Here, we describe two new Bennaria species from Papua New Guinea and give preliminary notes on their ecology. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

New Guinea is one of the last remaining regions of extensive tropical forest and is an important biodiversity hotspot, yet most of its canopy ant species are poorly known. Here, we provide the first study of arboricolous ant communities of the genus Camponotus MAYR, 1861 from a lowland rainforest in New Guinea. We censused Camponotus nests in trees from two 0.32 ha forest plots in primary forest (389 trees) and secondary forest (296 trees) and explored their species diversity and nesting preferences. In total, 293 nests of 19 species were found. In 16 of the 19 species, major workers exhibited a set of morphological traits (i.e., flattened anterior part of head, swollen fore femora and maximal distance between frontal carinae greater than a third of head width) associated with phragmosis, an adaptation for arboricolous nesting. In primary forest, we detected 15 species in 124 nests versus only eight species in 169 nests in secondary forest. Only four species were shared between the two forest plots. Camponotus species differed significantly in their prefer-ences for nesting microhabitats in both forest plots, ranging from species that were opportunistic and relatively abundant to those that specialized and nested only in living tree branches high in the canopy where they tended myrmecophilous scale insects. Of the 19 species collected, 13 are newly reported for New Guinea, including four that are described here as new species: Camponotus anezkae sp.n., Camponotus rotundus sp.n., Camponotus triangulatus sp.n. and Campo-notus wanangus sp.n. In addition, Camponotus aruensis KARAVAIEV, 1933 is redescribed. Diagnostic features for species identification, digital photos of all available castes and morphological measurements are provided. The study demons-trates the high diversity of arboricolous Camponotus ants and their nesting habits within a single tropical forest site. Source
