Diptera Stelviana. A dipterological perspective on a changing alpine landscape. Vol. 2 Studia Dipterologica Supplement 21

Description:

Text English. In the second volume of the series 'Diptera Stelviana', further results are published from the survey of the Diptera (flies and midges) in the South Tyrol part of the Stilfserjoch National Park (Italian Alps). Five Malaise traps were used, which were set up during the vegetative period of 2005 along a transect from the submontane to the alpine altitudinal zones (940 m to 2,135 m above NHN). Includes a comprehensive historical account of dipterological research in the South Tyrol since 1860. In the first part of this series which was published in 2008 more than 25.000 specimens of Diptera were dealt with. In the current volume results on a further 25,687 specimens are presented. The identified flies and midges belong to 900 species and represent 27 Diptera families. The results are given in 29 individual reports in which 29 international specialists have collaborated. Although there have been dipterological investigations in the study area since 1860, an additional 476 species have been found in the identified Diptera that were not previously known from South Tyrol. Although the fauna of Italy is rich and relatively well known, the present investigations in the

Stilfserjoch National Park have nevertheless added a further 109 species as new records for Italy. In both volumes of 'Diptera Stelviana' 1,248 species are recorded for the first time from South Tyrol and 357 species for the first time from Italy. The Diptera family Tachinidae is dealt with in particular detail in the second volume. A review is given of the 360 species that were collected

between 1860 and 2009 in the region of the presentday province of Bozen-South Tyrol. Seven taxa are described as new for science: Apiloscatopse ziegleri sp. nov. [Scatopsidae], Chrysosomopsis macrocercus sp. nov. [Tachinidae], Dinera fuscata occidentalis ssp. nov. [Tachinidae], Lonchaea stelviana sp. nov. [Lonchaeidae], Megaselia ziegleri sp. nov. [Phoridae], Meoneura pohlae sp. nov. [Carnidae], and Pneumia glabella sp. nov. [Psychodidae]. Eleven maps and 16 diagrams, 137 drawings and 45 photographs of

morphological details, 20 other photographs as well as 52 photographs of living flies in their natural habitats (altogether 282 figures)

illustrate the contributions. The second volume of the 'Diptera Stelviana' concludes with an overview of the results, a bibliography for

the General Part, summaries in Italian and German, a list of the collaborating authors, an index of the illustrations of Diptera species,

and an index of the dipterological names.
