UK Sawfly Checklist 1 Version: 18.11.2008 CHECKLIST OF BRITISH AND IRISH HYMENOPTERA SYMPHYTA A. D. Liston & D. A. Sheppard AL: Deutsches Entomologisches Institut, Eberswalder Str. 84, 15374 Müncheberg, Germany DS: 10 Stainfield Road, Hanthorpe, Bourne, Lincs., PE10 0RE Introduction Fifty years have passed since the publication of the final part of Robert B. Benson’s three part identification key to the “Symphyta” of the British Isles (Benson 1951, 1952, 1958). The importance of these works can hardly be overstated. Whilst the first two parts were based substantially on the acute monography by Eduard Enslin (Enslin 1912-1918), Benson’s treatment of the Nematinae represented an original and significant step forward in our knowledge of this subfamily. The results of subsequent research on the British and Irish sawfly fauna were collated by Fitton et al. (1978). Since then, renewed investigation of the taxonomy of West Palaearctic Symphyta has led to a great number of taxonomic and nomenclatural changes, affecting many taxa occurring in the British Isles. Of particular value in accessing the very extensive but widely scattered literature on sawflies, is the online database “Electronic World Catalog of Symphyta (ECatSym)” (Taeger & Blank 2008). Unfortunately, the only identification guide to the European “Symphyta” published since 1958 with a more than local geographical scope, by Zhelochovtsev (1988), suffers from its own particular weaknesses, such as the reliance placed on the opinions and illustrations of E. Lindqvist for the treatment of the Nematinae. Serious mistakes in the translation from Russian make the later English language editions of this work even more difficult to use. Special problems are attached to the interpretation of records for some species not found in the British Isles since their inclusion in the works by Leach (1817) and Stephens (1835). Some of these are probably extinct, but their status as in the British Isles has in many cases never been unequivocally proved: see for example Benson (1943a). We therefore maintain the practice, as in Fitton et al. (1978), of marking names of such taxa with a preceding “?”. Further, the taxonomic status of some of the nominal taxa described from the British Isles by Hill, Stephens, Newman and Cameron is still unclear, particularly where no type material has been located. Authorship and date of publication of taxa first described by Geoffroy, Panzer, Klug, Serville. Lepeletier, Zaddach and Brischke are adopted from the bibliographic researches of Taeger & Blank (1996, 2006) and Blank & Taeger (1998). Arrangement of list The listing of superfamilies is alphabetical, with families, subfamilies, tribes, genera, subgenera and species listed alphabetically within these. Genera. The generic classification used here mainly follows the system of Benson (1951-1958). This has the advantages of being relatively simple and widely known. The present lack of phylogenetic analyses for most groups of Symphyta (but see Nyman et al. 2006 on the Nematinae), which might support alternative generic classifications, makes the adoption here of some of the recently proposed genera at least seem premature. Whilst it is probable that some of these will in the future come to be recognised as valid, they are listed here either as synonyms or as “subgenera” of the genera treated by Benson. Generally, the lack of detailed morphological and biological studies on the larvae of many European sawfly species, must be regarded as a major obstacle to our understanding of their phylogeny. For each species name, the genus in which it was originally described follows the author’s name and date, where this differs from its current placement. Species names considered to be synonyms are treated in the same way as valid names, i. e. where necessary, the spelling is amended to agree with the gender of the genus in which it is at present placed. In some cases the most commonly used spelling in the literature therefore differs from that which appears here (e.g. Nematus astutus Cameron and Pristiphora (Lygaeotus) astutus (Cameron)). This should be borne in mind when searching the list for synonym names. Synonymy. The genus and species group names are included selectively in the synonymy. For a complete current synonymy of all these, including important misidentifications, see ECatSym (Taeger & Blank 2006). Names have only been included below as synonyms when they fulfil one or both of the following criteria: -has at some time been used for a taxon occurring in the British Isles. 2 -used in widely consulted works on taxonomy or distribution, or in original accounts of biological characters / descriptions of immature stages. The use of a question mark (?) preceding names in the list has two different meanings: 1) in combination with a taxon listed as valid, doubt is indicated as to validity of previous British records 2) in combination with a synonym, doubt is indicated on the taxonomic status of that taxon. Distribution. Area covered is the British Isles north to and including Shetland, but excluding the Channel Islands: see Sheppard (1990) on the sawfly fauna of the latter. Distribution of species within the British Isles is roughly indicated by the letter(s) following the valid species name, representing the countries from which it is recorded: England (E), Wales (W), Scotland (S) and Ireland (I) . The Isle of Man is not considered separately, because of a lack of data. It should be noted that several species were mistakenly listed as occurring in Scotland by Liston (1995). A reference is given for species first recorded in the British Isles since the last checklist by Fitton et al. (1978). Acknowledgements We are most grateful to Dr. M. G. Fitton for his work on an earlier version of this checklist. Guy Knight supplied much new information on the fauna of Wales, based mostly on his original research.

  • (Hymenoptera, Tenthredinidae) – a New Pest Species of Ash Tree in the Republic of Moldova
    Muzeul Olteniei Craiova. Oltenia. Studii şi comunicări. Ştiinţele Naturii. Tom. 36, No. 1/2020 ISSN 1454-6914 Tomostethus nigritus F. (HYMENOPTERA, TENTHREDINIDAE) – A NEW PEST SPECIES OF ASH TREE IN THE REPUBLIC OF MOLDOVA MOCREAC Nadejda Abstract. In the Republic of Moldova, the ash tree is a common forest species, used in the reforestation and afforestation of woods and territories, and widely used as an ornamental tree in cities and along roads. For more than ten years, our ash tree woods have been severely defoliated by the ash weevil Stereonychusfraxini (De Geer, 1775) from Curculionidae family. In the vegetation period of 2018 and 2019, defoliation was seen on ash trees, caused by unknown sawfly larvae species from the Tenthredinidae family. The analyses showed that these pests belong to the Hymenoptera order – the privet sawfly – Macrophya punctumalbum (Linnaeus, 1767), and Tomostethus nigritus (Fabricius, 1804), the last one being a new species for the fauna of the Republic of Moldova. The biggest ash defoliations caused by the Tomostethus nigritus larvae were recorded in the centre of the country, especially in the Nisporeni and Tighina Forest Enterprises and in the “Plaiul Fagului” Scientific Reserve, as well as in the urban space. Keywords: Ash Black sawfly, Tenthredinidae, ash tree, outbreaks, defoliations, Republic of Moldova. Rezumat. Tomostethus nigritus F. (Hymenoptera, Tenthredinidae) – specie nouă de dăunător al frasinului în Republica Moldova. În Republica Moldova, frasinul este o specie obișnuită, folosită nu numai în reîmpădurire și împădurire dar utilizat pe scară largă ca arbore ornamental în parcurile din orașe și de-a lungul drumurilor. Mai bine de zece ani, pădurile de frasin sunt defoliate anual de către trombarul frunzelor de frasin Stereonychus fraxini (De Geer, 1775) din familia Curculionidae.

  • Alien and Invasive Species of Harmful Insects in Bosnia and Herzegovina
    Alien and invasive species of harmful insects in Bosnia and Herzegovina Mirza Dautbašić1,*, Osman Mujezinović1 1 Faculty of Forestry University in Sarajevo, Chair of Forest Protection, Urban Greenery and Wildlife and Hunting. Zagrebačka 20, 71000 Sarajevo * Corresponding author: [email protected] Abstract: An alien species – animal, plant or micro-organism – is one that has been introduced as a result of human activity to an area it could not have reached on its own. In cases where the foreign species expands in its new habitat, causing environmental and economic damage, then it is classified as invasive. The maturity of foreign species in the new area may also be influenced by climate changes. The detrimental effect of alien species is reflected in the reduction of biodiversity as well as plant vitality. A large number of alien species of insects are not harmful to plants in new habitats, but there are also those that cause catastrophic consequences to a significant extent. The aim of this paper is to present an overview of newly discovered species of insects in Bosnia and Herzegovina. The research area, for this work included forest and urban ecosystems in the territory of Bosnia and Herzegovina.

  • Prioritising the Management of Invasive Non-Native Species
    PRIORITISING THE MANAGEMENT OF INVASIVE NON-NATIVE SPECIES Olaf Booy Thesis submitted to the School of Natural and Environmental Sciences in fulfilment for the requirements of the degree of Doctor of Philosophy Newcastle University October 2019 Abstract Invasive non-native species (INNS) are a global threat to economies and biodiversity. With large numbers of species and limited resources, their management must be carefully prioritised; yet agreed methods to support prioritisation are lacking. Here, methods to support prioritisation based on species impacts, pathways of introduction and management feasibility were developed and tested. Results provide, for the first time, a comprehensive list of INNS in Great Britain (GB) based on the severity of their biodiversity impacts. This revealed that established vertebrates, aquatic species and non-European species caused greater impacts than other groups. These high impact groups increased as a proportion of all non-native species over time; yet overall the proportion of INNS in GB decreased. This was likely the result of lag in the detection of impact, suggesting that GB is suffering from invasion debt. Testing methods for ranking the importance of introduction pathways showed that methods incorporating impact, uncertainty and temporal trend performed better than methods based on counts of all species. Eradicating new and emerging species is one of the most effective management responses; however, practical methods to prioritise species based both on their risk and the feasibility of their eradication are lacking. A novel risk management method was developed and applied in GB and the EU to identify not only priority species for eradication and contingency planning, but also prevention and long term management.

Seven new species of Nematinae (Tenthredinidae) from Japan and Korea are described: Pachynematus hirowatari spec. nov, P. hayachinensis spec. nov., Pristiphora nigrocoreana spec. nov, P. issikii spec. nov., P. shinoharai spec. nov, Pontania nipponica spec. nov. and Euura soboensis spec. nov. Pristiphora punctifrons (Thomson, 1871) is new record for Japan. Introduction Matsumura (1912) was the fi rst to study intensively the sawfl y fauna of Japan. However, the Nematinae sawfl ies are a group that has been neglected and its species are still poorly known. As a comparison, 116 Nematinae species occur in the post-Trianon Hungary (93,000 mi2) (Haris, 2001), yet only 94 species are recorded from Japan (377,835 mi2). In this paper, I add eight species to the Japanese and Korean fauna, seven of which are new and one is new record. A revision of the Nematinae of Japan and the Far East will be published in a separate paper. The material studied is mainly in the Takeuchi collection deposited in the Univer- sity of Osaka Prefecture; one species is described from the collection of the National Museum of Natural History, Washington D.C.
