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.
Biodiversity knowledge is widely heterogeneous across the Earth's biomes. Some areas, due to their remoteness and difficult access, present large taxonomic knowledge gaps. Mostly located in the tropics, these areas have frequently experienced a fast development of anthropogenic activities during the last decades and are therefore of high conservation concerns. The biodiversity hotspots of Southeast Asia exemplify the stakes faced by tropical countries. While the hotspots of Sundaland (Java, Sumatra, Borneo) and Wallacea (Sulawesi, Moluccas) have long attracted the
BackgroundTo date only one species of Limbodessus diving beetles has been reported from the Island of New Guinea, L.
compactus (Clark, 1862), which is widerspread in the Australian region.New informationWe describe two new species of microendemic New Guinea Limbodessus and use a compact descriptive format flanked by enriched online content in wiki powered species pages. Limbodessus
baliem
sp.n. is described from ca. 1,600 m altitude in the Baliem Valley of Papua and Limbodessus
alexanderi
sp.n. from >3,000 m altitude north of Sugapa, Papua.Based on our analysis, we also transfer three species from other genera to Limbodessus Guignot, 1939, with the following changes: Limbodessus
deflectus (Ordish, 1966), new combination; Limbodessus
leveri (J. Balfour-Browne, 1944), new combination; and Limbodessus
plicatus (Sharp, 1882), new combination.
Diversity study of beetles from Family of Tenebrionidae was conducted at forest areas in the district Bonggo, Sarmi Papua from September-October 2010. The Beetles were collected using a cross-wet trap placed at three locations in the former logged merbau (Intsia sp.) and sengon (Albisia sp.) areas. The data collected were the number of species and number of individuals in each species with indicators to compare beetle diversity based on species richness (s). The result showed that out of a total of 8 individuals of Tenebrionidae, there were seven different species identified during field observations. The highest number of beetles was found in the former logged Intsia spare as (4 species at third location and 2 species at the first location) followed by former logged Albisia sp areas (1 species at both locations).Key words: diversity, beetles, Tenebrionidae; Bonggo District, Jayapura.
Ornitophera sp. is one of the groups of butterflies endemic in Papua and West Papua provinces. The significant morphological differences between male and female butterflies (dimorphism) are in the shape, size and color of the wings. Morphological characteristics are important sources of information. Based on the results of specimen collections at the Papua Insect Collection Laboratory (KSP) Jayapura, there are several species from various locations in Papua. The variation in dimorphism is likely to occur in this species which gives rise to new sub-species. The purpose of this study was to record the dimorphism of the endemic Bird Wing of Papua which had been stored in the Papua Insect Collection Laboratory (KSP) Jayapura. The method used is a direct measurement of the morphology of bird wing butterfly specimens stored in the KSP Laboratory, Cenderawasih University. Morphometric data were analyzed using the SPSS 20 and Multi Variate Statistical Package (MVSP 3.1) programs. The results obtained were 7 Ornithoptera species stored in the KSP Jayapura Laboratory, namely O. chiamera, O. goliath, O. meridionalis, O. paradisea, O. priamus, O. thitonus and O. rothschildi. Based on observations there are striking differences in color, shape and size between male and female in the same species. Key words: birdwing butterfly, Ornithoptera sp., KSP Jayapura, dimorphisme.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
