Mitteleuropäische (extra - mediterrane) Arealkerne des Dinodal am Beispiel von Köcherfliegen (Trichoptera).

Aus eigenen Daten und aus Literaturangaben werden mindesten 13 mitteleuropäische Regionen (außerhalb des Mediterrangebietes) mit Anhäufungen oder Vorkommen von stenendemischen Trichopterenarten genannt, die als Arealkerne und als mögliche Refugien während der letzten (Würm-) Kaltzeit dieser und weiterer Arten gedeutet werden. Diese Areale sind: das Massif Central, Teile des französischen und schweizerischen Jura, Schwarzwald und Vogesen, die Umgebung von Grenoble, die Bergamasker Alpen und ihre Umgebung, die Lessinischen Alpen, die Karawanken und ihre Umgebung, die Steirischen Randgebirge, die Hohe Tatra, der Bereich von Tschernogora – Rodna - Maramuresch, das Bihor-Gebirge und Teile der Südkarpaten.StichwörterZoogeography, area dynamics, Dinodal, Trichoptera, Central Europe, Pleistocene refugia.Extra-mediterranean centres of areas of Trichoptera of the European Dinodal. The analysis of distribution areas of stenochorous Trichoptera species results in the discovery of a minimum of 13 refugial centres in Central Europe (outside any traditionally known other refugia) which are situated in the Massif Central, in parts of the French and Swiss Jura, in the Black Forest and the Vosges, in the surroundings of Grenoble, in the region of the North Italian Lakes, in the Lessinian Alps, around the Karawanken, in the eastern Styrian mountains, in the High Tatra, in the region of ernogora, Rodna and Maramure, in the Bihor Mts and in the southern Carpathians.KeywordsZoogeography, area dynamics, Dinodal, Trichoptera, Central Europe, Pleistocene refugia

Untersuchungen über Bionomie, Präimaginalstadien und Verbreitung der europäischen Sorhagenia-Arten (Lepidoptera: Walshiidae).

Die Bionomien der europäischen Arten der Gattung Sorhagenia werden beschrieben. Die Raupe von Sorhagenia lophyrella Douglas lebt einzeln zwischen zusammengesponnenen Blättern von Rhamnus cathartica und Rhamnus saxatilis, die von Sorhagenia rhamniella Zeller gesellig zwischen zusammengesponnenen Blüten von Rhamnus cathartica, jene von Sorphagenia janiszewskae Ridl miniert in den disjährigen Trieben von Rhamnus frangula seltener in anderen Rhamnus-Arten. Sorphagenia lophyrella und Sorhagenia rhamniella überwintern als Ei, Sorhagenia janiszewskae vermutlich als Imago in beiden Geschlechtern. Nach dem Material aus Museen und Privatsammlungen sowie aus eigenen Aufsammlungen wird ein Überblick über die Verbreitung der Arten gegeben. Raupe und Puppe werden beschrieben und abgebildet, Unterscheidungsmerkmale der Raupen angegeben.The bionomics of the european species of the genus Sorhagenia are described. The caterpillar of Sorhagenia lophyrella Douglas lives singly between spun leaves of Rhamnus cathartica and Rhamnus saxatilis, that of Sorhagenia rhamniella Zeller lives sociably between spun blossoms of Rhamnus cathartica, that of Sorphagenia janiszewskae Ridl mines in this years shoots of Rhamnus frangula and more rarely in other species of Rhamnus. Sorphagenia lophyrella and Sorhagenia rhamniella hibernate as eggs, Sorhagenia janiszewskae probably as imago in both sexes. On the basis of material from museums and private collections and from the author's collections a survey is given of the distribution of the species. Caterpillar and pupa are described and illustrated, and distinctive characteristics of the caterpillars are mentioned

Distribution of Ecnomus McLachlan, 1864 (Trichoptera, Ecnomidae) from the Lower Mekong River with a description of Ecnomus stungtrengensis new species

Trichoptera were surveyed from four different physiographic regions of the Lower Mekong River, including the Northern Highlands, the Khorat Plateau, the Tonle Sap Basin and the Mekong Delta in Myanmar, Laos, Thailand, Cambodia and Vietnam.Twenty-three species of the genus Ecnomus, including a new species, were identified and mapped. Ecnomus mammus Malicky & Chantaramongkol, 1993 is a common species which is found from Tonle Sab Basin and Mekong Delta. Ecnomus alkmene Malicky & Chantaramongkol, 1997, E. volovicus Malicky & Chantaramongkol, 1993 and Ecnomus quordaio Malicky, 1993 are the common species in the area of the Northern Highlands and the Khorat Plateau. Ecnomus plotin Malicky & Laudee 2010 is found in the Mekong Delta. Ecnomus triangularis Sun, 1997 is a new species record for Southeast Asia. In addition, E. stungtrengensis sp. n. is described and illustrated. The male genitalia of E. stungtrengensis sp. n. are clearly different from those of other species in the genus Ecnomus by the shape of superior appendages which are slender and bent downwards distally in lateral view

Longitudinal river zonation in the tropics: examples of fish and caddisflies from endorheic Awash river, Ethiopia

Primary Research PaperSpecific concepts of fluvial ecology are well studied in riverine ecosystems of the temperate zone but poorly investigated in the Afrotropical region. Hence, we examined the longitudinal zonation of fish and adult caddisfly (Trichoptera) assemblages in the endorheic Awash River (1,250 km in length), Ethiopia. We expected that species assemblages are structured along environmental gradients, reflecting the pattern of large-scale freshwater ecoregions. We applied multivariate statistical methods to test for differences in spatial species assemblage structure and identified characteristic taxa of the observed biocoenoses by indicator species analyses. Fish and caddisfly assemblages were clustered into highland and lowland communities, following the freshwater ecoregions, but separated by an ecotone with highest biodiversity. Moreover, the caddisfly results suggest separating the heterogeneous highlands into a forested and a deforested zone. Surprisingly, the Awash drainage is rather species-poor: only 11 fish (1 endemic, 2 introduced) and 28 caddisfly species (8 new records for Ethiopia) were recorded from the mainstem and its major tributaries. Nevertheless, specialized species characterize the highland forests, whereas the lowlands primarily host geographically widely distributed species. This study showed that a combined approach of fish and caddisflies is a suitable method for assessing regional characteristics of fluvial ecosystems in the tropicsinfo:eu-repo/semantics/publishedVersio

The Trichoptera barcode initiative: a strategy for generating a species-level Tree of Life

DNA barcoding was intended as a means to provide species-level identifications through associating DNA sequences from unknown specimens to those from curated reference specimens. Although barcodes were not designed for phylogenetics, they can be beneficial to the completion of the Tree of Life. The barcode database for Trichoptera is relatively comprehensive, with data from every family, approximately two-thirds of the genera, and one-third of the described species. Most Trichoptera, as with most of life’s species, have never been subjected to any formal phylogenetic analysis. Here, we present a phylogeny with over 16 000 unique haplotypes as a working hypothesis that can be updated as our estimates improve. We suggest a strategy of implementing constrained tree searches, which allow larger datasets to dictate the backbone phylogeny, while the barcode data fill out the tips of the tree. We also discuss how this phylogeny could be used to focus taxonomic attention on ambiguous species boundaries and hidden biodiversity. We suggest that systematists continue to differentiate between ‘Barcode Index Numbers’ (BINs) and ‘species’ that have been formally described. Each has utility, but they are not synonyms. We highlight examples of integrative taxonomy, using both barcodes and morphology for species description. This article is part of the themed issue ‘From DNA barcodes to biomes’
