Nineteen species were recognised when the Sciarid fauna of New Zealand was reviewed for the first time (Tonnoir & Edwards 1927), and most of them were placed in the catch-all genus Sciara Meigen. Following a recent revision of types (Menzel & Mohrig 1999) and study of a large amount of new material collected by the junior author… on New Zealand s North Island in the southern summer 1992/93, the authors now list 53 species of Sciaridae, 40 of which are described as new to science. This also provides a more solid basis for zoo-geographic discussion of a phylogenetically old group as it occurs in a biogeographically interesting region such as New Zealand, known for its many endemics. The surprising results: The Sciarid fauna of New Zealand seems to be rather unspectacular, seen from a Palaearctic point-of-view. As a whole 51 apparently indigenous species belong to 6 genera that are also distributed in the Holarctic. Corynoptera Winnertz alone is represented by 32 species. There is no endemic taxon at the generic level. Faunal relationships with the southern Palaearctic and with Micronesia are discussed, with Epidapus Haliday and Corynoptera serving as examples. Analysis of the adult morphology leads to the conclusion that the New Zealand Sciarid fauna includes at least two faunal horizons which can be correlated with Tertiary land bridges known as the Inner and Outer Melanesian Arc. The number of Sciarid species imported to New Zealand by man's activities is very small. Keys to genera and species combined with detailed illustrations of all the important diagnostic char-acters enable the males of all Sciarid species so far recorded from New Zealand to be identified. 101 pp., 55 figs, br. gr. 8 [24 x 16.7 cm].

Today's southern hemisphere fauna and flora are renowned for their transantartic relaionships, dating back to the break up of Gondwanaland by the end of the Jurassic period, some 150 million years ago. Among Dipterists, the southern continents have long been known to provide the habitats for phylogenetically interesting Sciaroid…ea, an extremely diverse, cosmopolitan group of bibionomorph flies that includes the well known fungus gnats and gall midges. New Zealand is no exception in this respect, where two species, Heterotricha novaezealandiae and Ohakunea bicolor, were described as early as 1927 by A. L. Tonnoir and F. W. Edwards, and reamain unplaceable within the current family-level classification of the Sciaroidea. The enigmatic relationships of sciaroids like Heterotricha and Ohakunea are the main reason for the ongoing debate on the higher-level systematics within the superfamily. Given that New Zealand's fauna is of such extraordinary significance for understanding the evolution of the world's Sciaroidea, it comes as sonewhat of a surprise that the study by Tonnoir and Edwards has not inspired subsequent, intensive sciaroid research in this part of the world for the last 75 years. This may be partly explained by the worldwide decline in biosystematic expertize, but also partly because the completeness of Tonnoir and Edwards' work has apparently been overestimated. As shown in this paper, New Zealand's sciaroid fauna is far from exhaustively studied. By taking the full methodological advantage of modern, highly effective Malaise trapping, the authors have recently collected and studied a tremendously large and diverse set of samples of Sciaroidea from indigenous forests of New Zealand's main islands. This material, supplemented by collections of numerous New Zealand entomologists over the past 20 years, yielded five new species of sciaroid Diptera which are classified in a new family named Rangomaramidae. Adult morphology, biology and distribution of Rangomaramidae (*long-winged fungus gnats*) are described and illustrated by numerous line drawings as well as light and scanning electron microscopic images. The origin and evolution of Rangomaramidae are discussed in the contex of previous hypotheses on the phylogenetic relationships within Sciaroidea. Rangomaramidae appear to be a relict group of Sciaroidea, with a limited modern dustribution and a comparatively small number of extant species. The new taxa may shed more light on the relationship between fungus gnats and gall midges and on the unresolved question of the sister group of Cecidomyiidae. New taxa: Rangomaramidae n. fam., Rangomarama edwardsi n. sp., Rangomarama humboldti n. sp., Rangomarama leopoldinae n. sp., Rangomarama matilei n. sp., Rangomarama tonnoiri n. sp. 60 pp., 81 figs, br. gr. 8 [24 x 16.7 cm].

Traditionell werden die morphologisch ursprünglichsten Vertreter der Gallmücken (Cecidomyiidae) in der Unterfamilie Lestremiinae" vereint - mycetophage Formen ohne Galleninduktion an Höheren Pflanzen. Alle Aspekte der Biologie dieser Holzmücken" - so auch ihre Taxonomie - standen von jeher am Rande des Forschungsinteresses. Folg…lich sieht sich heute der ökologisch-faunistisch tätige Dipterologe mit einer zwar artenreichen, aber unbestimmbaren" Problemgruppe konfrontiert; der an der Phylogenie der Mycetophiloidea Interessierte scheitert beim Literaturstudium an der unzureichenden Dokumentation vieler hier eingeschlossener Taxa. Anliegen des Autors ist es, einen Beitrag zur Bewältigung dieser insgesamt unbefriedigenden Siuation zu leisten. Mit der vorliegenden Arbeit werden die Lestremiinae" einer Revision unterzogen, die erstmalig die gesamte Holarktis berücksichtigt. Auf der Grundlage einer vereinheitlichten Terminologie und neuer Ansätze zur Merkmalserkennung und -bewertung wird das Imaginalstadium vergleichend-morphologisch untersucht. Soweit möglich, wird auf das Originalmaterial früherer Autoren zurückgegriffen, ergänzt durch die wichtigsten gruppenspezifischen Museumskollektionen und Aufsammlungen des Autors. Im Ergebnis können 318 valide Lestremiinen-Arten bestätigt werden; für 172 davon wird eine Nachbeschreibung geliefert. Weitere 55 Spezies waren bereits im Vorfeld dieser Publikation neubeschrieben worden. Zahlreiche textbegleitende Abbildungen und Bestimmungsschlüssel erleichtern die Wiedererkennung der Arten. Insgesamt werden 41 Merkmale auf ihre evolutive Transformationsrichtung hin analysiert. Auf daraus resultierenden Autapomorphien gründet sich die Diagnose supraspezifischer Taxa, wobei der dem Wiederauffinden von Informationen dienende Zweck einer Klassifikation nie aus dem Blickfeld gerät. Das hier vorgeschlagene System der Lestremiinae" gliedert 34 Gattungen in 10 Tribus. Der präsentierte Stammbaum für die Lestremiinae" bedient sich argumentatorisch synapomorpher Merkmale für die Postulierung von Schwestergruppenverhältnissen. Der paraphyletische Charakter der Lestremiinae" wird nachdrücklich unterstrichen - ein deutlicher Fingerzeig auf die zukünftige Notwendigkeit einer Neugliederung des gesamten Verwandtschaftskomplexes. Faunistische Literaturangaben werden - soweit möglich - durch Nachuntersuchung des zugrundeliegenden Materials verifiziert und in Auswertung zusätzlicher Aufsammlungen des Autors vermehrt. Demnach stehen derzeit 92 nachgewiesenen Arten für die Nearktis 278 paläarktischen Arten gegenüber. 552 pp., 237 figs, br. gr. 8 [24 x 16.7 cm].

Lestremiinae (wood midges) are a group of finy forest-dwelling dipterans with a world-wide distribution. The present inventory, coupled with a taxonomic revision, documents of occurrence of 230 species, 28 genera and 9 tribes of Lestremiinae in Fennoscandia and Denmark. Species-based information on distribution and phenology is…provided and the biogeographic patterns identified are discussed. Diagnoses, illustrations and keys facilitate the identification of species (adults). An illustrated key makes the identification of all the supraspecific taxa known from the Holarctic region possible. Sixty new synonyms and 12 new combinations are proposed, and 1 new genus and 56 new species are described. The adult morphology of Lestremiinae is outlined and re-examined in the context of phylogeny and classification. Evidence is supplied that the Lestremiinae are a paraphyletic assemblage. A proposal for a natural system of the Cecidomyiidae (gall midges), including Lestremiinae, is presented. The systematic position of the Cecidomyiidae in relation to the Sciaroidea is briefly discussed. The study of the taxonomy of Holarctic and Fennoscandian Lestremiinae is outlined in a historical context. The methods of studying adult wood midges are explained. 333 pp., 104 figs, hardcover gr. 8 [24.6 x 17 cm].

This revision summarizes the results of four years of taxonomic and faunistic research into the Porricondylinae of Sweden. Porricondylinae are a little-sutdied, globally distributed group of forest-dwelling Diptera, with several hundred named species in Europe and fewer than 30 species recorded in Sweden prior to this study. The… present inventory shows 206 species and 53 general of Porricondylinae to occur in Sweden, including 57 species and 10 genera new to science. Male genitalia and other adult morphological structures of taxonomic significance are illustrated for almost all species. Other indentification tools, such as keys and diagnoses, are provided for tribes, genera and species. The conceptions of supraspecific taxa are outlined in a historical context. Revision work takes account of taxa from all the Holarctic region, resulting in 81 new synonyms and 49 new combinations. Based on actual specimens adult morphology of Porricondylinae is reexamined and characters observed are analyzed in terms of phylogeny. A new classification is proposed that eliminates the traditional, paraphyletic Porricondylinae, instead favoring two large subdivisions, Winnertziinae and Porricondylinae sensu stricto. 392 pp., 181 figs, hardcover gr. 8 [24.6 x 17 cm].
