Melanesomyia, a Tribally Unplaced New Genus of Dexiinae (Diptera: Tachinidae) from Indonesia (Maluku) and Papua New Guinea, With Description of Two New Species

A brief review of Australasian dexiine systematics is given. A tribally unplaced new genus, Melanesomyia , is described to accommodate two new species and an undescribed species from the Highlands of Papua New Guinea, as well as the generically unplaced species " Dexia" nivifera Walker, 1861, from the Moluccas Islands, Maluku Province, Indonesia. New species are: M. kraussi and M. wauensis. A key to the species is provided. Melanesomyia appears to have affinity (likely an example of homoplasy) with the Australian genus Trichostylum Macquart, 1851, and Rasiliverpa Barraclough, 1992, which is known only from New Caledonia and Fiji.

New species and new records of Menegazzia (Parmeliaceae, lichenized ascomycetes) from Malaysia and Indonesia

The genus Menegazzia (Parmeliaceae, lichenized ascomycetes) in Malaysia and Indonesia is studied. Some specimens from Papua New Guinea are also included. The great majority of available specimens are from Kinabalu Park, State of Sabah, Malaysia. Three species are described as new to science, namely the two sorediate species M. capitata (from Sabah and Pahang in Malaysia) and M. sabahensis (from Sabah), and the fertile, primary species M. monospora (from Sabah and Papua New Guinea). M. asahinae , M. dissoluta , and M. efflorescens are reported for the first time from Malaysia, and M. subsimilis is reported for the first time from Malaysia and Indonesia. The subgenus Megamenegazzia is newly described to accommodate the large, broad-lobed species with numerous perforations on the lower surface. M. efflorescens is selected as the type species for the new subgenus. Notes are also provided on the type specimens of Hypogymnia pectinatula , a species originally considered as belonging to Menegazzia .  © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 153 , 489–499.     

New Macroderoides (Digenea: Macroderoididae) from Florida gar, with molecular phylogeny of the genus

Macroderoides minutus n. sp. is described based on specimens collected from the Florida gar (Lepisosteus platyrhincus) from Orange Lake, Alachua County, Florida. The new species is the ninth recognized species of Macroderoides and is morphologically closest to Macroderoides flavus and Macroderoides typicus. It differs from both species in having a smaller body, ventral sucker larger than the oral sucker, substantially lower body length to width ratio, fewer and larger eggs, and other characters. A comparison of sequences of nuclear rDNA (partial 18S, complete ITS region, and partial 28S) of the new species, with sequences of 5 other Macroderoides, convincingly supports the status of M. minutus as a new species. Molecular phylogenetic analysis, including all North American Macroderoides species except for Macroderoides parvus, has demonstrated the presence of 2 distinct clades, 1 including Macroderoides spinifer + (Macroderoides minutus n. sp. + Macroderoides texanus) and the other including Macroderoides trilobatus + (M. typicus + M. flavus). The tree topology suggests that the similarity in body proportions among M. minutus n. sp., M. typicus + M. flavus is not a result of close phylogenetic relationship. It has also revealed for the first time the phylogenetic affinities of M. flavus, which is the only North American member of Macroderoides that switched from holostean fishes to teleosts.     

A New Species of Muscicapa Flycatcher from Sulawesi,Indonesia

The Indonesian island of Sulawesi, a globally important hotspot of avian endemism, has been relatively poorly studied ornithologically, to the extent that several new bird species from the region have been described to science only recently, and others have been observed and photographed, but never before collected or named to science. One of these is a new species of Muscicapa flycatcher that has been observed on several occasions since 1997. We collected two specimens in Central Sulawesi in 2012, and based on a combination of morphological, vocal and genetic characters, we describe the new species herein, more than 15 years after the first observations. The new species is superficially similar to the highly migratory, boreal-breeding Gray-streaked Flycatcher Muscicapa griseisticta, which winters in Sulawesi; however, the new species differs strongly from M. griseisticta in several morphological characters, song, and mtDNA. Based on mtDNA, the new species is only distantly related to M. griseisticta, instead being a member of the M. dauurica clade. The new species is evidently widely distributed in lowland and submontane forest throughout Sulawesi. This wide distribution coupled with the species'' apparent tolerance of disturbed habitats suggests it is not currently threatened with extinction.     

New Coleoptera records from New Brunswick, Canada: Mycetophagidae, Tetratomidae, and Melandryidae

We report 21 new species records for the Coleoptera fauna of New Brunswick, Canada, seven of which are new records for the Maritime provinces. Four species of Mycetophagidae (Litargus didesmus Say, Litargus tetrapilotus LeConte, Mycetophagus punctatus Say, and Mycetophagus quadriguttatus Müller) are newly reported for the province of New Brunswick. Litargus didesmus is newly recorded for the Maritime provinces. Seven species of Tetratomidae are added to the faunal list of New Brunswick: Eustrophus tomentosus Say, Penthe obliquata (Fabricius), and Tetratoma tessellata Melsheimer are new to New Brunswick: Hallomenus serricornis LeConte, Pisenus humeralis Kirby, Synstrophus repandus (Horn), and Tetratoma variegata Casey, which are newly recorded for New Brunswick and the Maritime provinces. Ten additional species of Melandryidae are reported from New Brunswick, of which Orchesia cultriformis Laliberté, Orchesia ovata Laliberté, Phloeotrya fusca (LeConte), Scotochroides antennatus Mank, Spilotus quadripustulatus (Melsheimer), Symphora flavicollis (Haldeman), Symphora rugosa (Haldeman), and Zilora hispida LeConte are new for the province, and Microscapha clavicornis LeConte and Zilora nuda Provancher are newly recorded for the Maritime provinces. In addition, we report numerous additional records for three species of Mycetophagidae and one species of Melandryidae previously recorded from New Brunswick that suggest these species are more widely distributed than previously known. Collection, habitat data, and distribution maps are presented for all these species.

Metahuntemannia triarticulata sp.n., M. arctica sp.n. and M. bifida sp.n. arc described. M. triurficulata and M. arctica belong to the 'spinosa' group within the genus Metahuntemannia Smirnov. From the closely related species, M. triarticulata differs in the possession of 3-segmented Enp P3, M. arctica in the segmentation of the Al, and both new species in the setation of their swimming legs P1–P5. M. hifida belongs to the 'talpa' group within Metahuntemannia and differs from the closely related species in the setation of the swimming legs P2–P4. The species relationships and the phylogeny within the genus are discussed. All species were collected at the Iceland-Faroe Ridge from depths between 435 and 2500 m.     

Minidiscus,a New Recorded Nanodiatom Genus for China

Minidiscus trioculatus, M. comicus and M. chilensis are new records for China, and M. subtilis, is a new species. They differ from Thalassiosira species by their strutted processes and one single labiate process being distant from valve margin and they differ from each other by their areola patterns on valves and distribution patterns of strutted processes and the labiate process. A key to the species of Minidiscus is given. Minidiscus subtilis Gao, Cheng et Chin sp. nov., figs 7-8 Valves disc-shaped, slightly concave in center, weakly silicified, 3.5-5.5μm in diameter. Areola unequally radiate-striate, striae 8.5 / lμm. A narrow valve mantle without striae. Three strutted processes and a single labiate process located in the central area of the valve. Among them, one strutted process in the very center with the other two adjacent to it, forming an isometric triangle with the labiate process between the two subcentral strutted processes. Two small satellite pores in each base of the strutted processes. M. subtilis differs from M. chilensis mainly by their radiate striae continuously distributed from the valve center tothe margin.

The ant community response to the arrival of Monomorium sydneyense forel (Hymenoptera: Formicidae) at sulphur point,Tauranga, New Zealand

Abstract

Impacts of highly invasive ants in new ecosystems are well documented, but many more ant species are establishing in new ranges for which there is little or no information. We studied the effects of the recently discovered Australian ant, Monomorium sydneyense Forel, on the ant community of Sulphur Point in Tauranga, New Zealand. At the community scale, the species composition in invaded areas was significantly different from that in areas free of M. sydneyense. However, no single ant species was significantly more or less abundant in the presence of M. sydneyense. Some resident ant species categorised in the same functional group as the invader appeared to be scarcer when sympatric with M. sydneyense, but the local abundances of these species were always spatially variable, so the effects were not statistically significant Patchy distribution of M. sydneyense, and other aspects of its behaviour, such as poor foraging abilities and a lack of unicoloniality (where there is little or no aggression between conspecific ants from spatially separate nests), appear to allow resident ant species to coexist with M. sydneyense at Sulphur Point.
