In der Arbeit werden historische und aktuelle Funde von Hausfliegen der Familien Fanniidae und Muscidae auf den Inseln der Tristan da Cunha-Gruppe im Südatlantik zusammengefaßt und diskutiert. Das aktuelle Material wurde 2005 auf den nördlichen Inseln, Tristan da Cunha und Nightingale, gesammelt. Insgesamt sind fünf Arten in vier Gattungen nachgewiesen, einschließlich der Erstnachweise von Fannia albitarsis Stein, 1911 innerhalb des Archipels und von Muscina stabulans (Fallén, 1817) auf der Insel Nightingale. Die korrekte taxonomische Einordnung von Coenosia trina Wiedemann, 1830 wird diskutiert. Auf die offensichtlich starke Verbreitung dieser Art und den möglichen negativen Einfluss auf die heimische Fauna wird ebenfalls hingewiesen.StichwörterDiptera, Muscidae, Fanniidae, Housefly, Lesser Housefly, Stable fly, Tristan da Cunha, Nightingale, Gough, Inaccessible, Island, South Atlantic.

Chironomid Fauna

The resurrection of trans-oceanic dispersal is the most striking aspect of a major shift in historical biogeography toward a more even balance between vicariance and dispersal explanations. Molecular dating of lineage divergences favors oceanic dispersal over tectonic vicariance as an explanation for disjunct distributions in a wide variety of taxa. Although many oceanic islands harbor a disproportionately high biodiversity and number of endemic taxa, the chironomid fauna of the South Atlantic islands of Gough, Nightingale and Tristan da Cunha apparently consists of 6 species only: Telmatogeton goughi sp. n. (described as male and female), Limnophyes minimus (Meigen), Smittia sp. (described as female), Thalassosmittia christinae sp. n. (described as female), Clunio jonesi sp. n. (described as male) and Allocladius lusciniolus Sæther et Andersen (described as female). Except for the marine T. goughi and C. jonesi the other species are parthenogenetic. Limnophyes minimus and A. lusciniolus dominate the chironomid fauna. Telmatogeton goughi is close to T. sanctipauli (Schiner). Thalassosmittia christinae differs from T. thalassophila (Bequaert et Goetghebuer) by having hairy eyes and antenna with subapical seta. Clunio jonesi differs from C. africanus and C. gerlachi by having ultimate flagellomere as long as the 4 preceding segments and gonostylus with only 1–2 apical spines. Allocladius lusciniolus differs from other known females of the genus by having 1–5 setae apically on M 1+2 .

Tristan Da Cunha Islands

1. Introduction Tristan da Cunha, Inaccessible, Nightingale and Gough Islands are similar in climate, physiography and vegetation, and form a single biogeographical province. Many animal species, including some endemics, occur on all of them, and the faunas of the four islands have the same general characteristics and show a common relationship to stocks in temperate South America. Any discussion of the fauna of the group must therefore consider all four main islands. Such a general evaluation is rendered difficult by variations in the intensity of study of the different islands and of different taxonomic groups. It is probably true today that the native land fauna of the archipelago is adequately known in outline, and that no native vertebrate or abundant large terrestrial invertebrate species awaits discovery. However, the smallei and less conspicuous land invertebrates and the majority of the shallow-water marine organisms are undoubtedly underworked, and much remains to be discovered about the detailed distribution, ecology and interrelationships of the island faunas. The present paper is no more than an interim review of the extent and deficiency of current knowledge.
