  • The Slugs of Britain and Ireland: Undetected and Undescribed Species Increase a Well-Studied, Economically Important Fauna by More Than 20%
    The Slugs of Britain and Ireland: Undetected and Undescribed Species Increase a Well-Studied, Economically Important Fauna by More Than 20% Ben Rowson1*, Roy Anderson2, James A. Turner1, William O. C. Symondson3 1 National Museum of Wales, Cardiff, Wales, United Kingdom, 2 Conchological Society of Great Britain & Ireland, Belfast, Northern Ireland, United Kingdom, 3 Cardiff School of Biosciences, Cardiff University, Cardiff, Wales, United Kingdom Abstract The slugs of Britain and Ireland form a well-studied fauna of economic importance. They include many widespread European species that are introduced elsewhere (at least half of the 36 currently recorded British species are established in North America, for example). To test the contention that the British and Irish fauna consists of 36 species, and to verify the identity of each, a species delimitation study was conducted based on a geographically wide survey. Comparisons between mitochondrial DNA (COI, 16S), nuclear DNA (ITS-1) and morphology were investigated with reference to interspecific hybridisation. Species delimitation of the fauna produced a primary species hypothesis of 47 putative species. This was refined to a secondary species hypothesis of 44 species by integration with morphological and other data. Thirty six of these correspond to the known fauna (two species in Arion subgenus Carinarion were scarcely distinct and Arion (Mesarion) subfuscus consisted of two near-cryptic species). However, by the same criteria a further eight previously undetected species (22% of the fauna) are established in Britain and/or Ireland. Although overlooked, none are strictly morphologically cryptic, and some appear previously undescribed. Most of the additional species are probably accidentally introduced, and several are already widespread in Britain and Ireland (and thus perhaps elsewhere).

  • The Slugs of Bulgaria (Arionidae, Milacidae, Agriolimacidae
    POLSKA AKADEMIA NAUK INSTYTUT ZOOLOGII ANNALES ZOOLOGICI Tom 37 Warszawa, 20 X 1983 Nr 3 A n d rzej W ik t o r The slugs of Bulgaria (A rionidae , M ilacidae, Limacidae, Agriolimacidae — G astropoda , Stylommatophora) [With 118 text-figures and 31 maps] Abstract. All previously known Bulgarian slugs from the Arionidae, Milacidae, Limacidae and Agriolimacidae families have been discussed in this paper. It is based on many years of individual field research, examination of all accessible private and museum collections as well as on critical analysis of the published data. The taxa from families to species are sup­ plied with synonymy, descriptions of external morphology, anatomy, bionomics, distribution and all records from Bulgaria. It also includes the original key to all species. The illustrative material comprises 118 drawings, including 116 made by the author, and maps of localities on UTM grid. The occurrence of 37 slug species was ascertained, including 1 species (Tandonia pirinia- na) which is quite new for scientists. The occurrence of other 4 species known from publications could not bo established. Basing on the variety of slug fauna two zoogeographical limits were indicated. One separating the Stara Pianina Mountains from south-western massifs (Pirin, Rila, Rodopi, Vitosha. Mountains), the other running across the range of Stara Pianina in the^area of Shipka pass. INTRODUCTION Like other Balkan countries, Bulgaria is an area of Palearctic especially interesting in respect to malacofauna. So far little investigation has been carried out on molluscs of that country and very few papers on slugs (mostly contributions) were published. The papers by B a b o r (1898) and J u r in ić (1906) are the oldest ones.

Für die Aufgliederung der Linien dubia dubia und dubia speciosa muß der letzte Käl- tehöhepunkt der Würmvereisung auslösend gewesen sein. Die Vorläufer von Clausilia dubia dubia und Clausilia dubia speciosa zeigen morphologische Paral- lelen zu den Formen ostösterreichischer Lößfaunen, aus denen auch Clausilia dubia obsoleta hervorgegangen sein muß. Wenn die Beziehungen der beiden ersteren zueinander auch sehr eng sind, sollten doch alle drei Linien als eine Ein- heit angesehen werden. Summary The abundant pleistocene material of Clausilia dubia from different cave and loess localities in Austria made it possible to study its present subspecific dif- ferentiation. Presumably the last pleniglacial period of the alpine Wurmian glacia- tion induced the development of the two lines Clausilia dubia dubia and Clau- silia dubia speciosa. The ancestor forms of Clausilia dubia dubia and Clausilia dubia speciosa show morphological similarities to these dubia specimens which occur in a lot of loess localities in Eastern Austria.

Wilson5 & Accepted: 08 July 2016 Michael Schrödl2,3 Published: 08 August 2016 Euthyneuran gastropods represent one of the most diverse lineages in Mollusca (with over 30,000 species), play significant ecological roles in aquatic and terrestrial environments and affect many aspects of human life. However, our understanding of their evolutionary relationships remains incomplete due to missing data for key phylogenetic lineages. The present study integrates such a neglected, ancient snail family Ringiculidae into a molecular systematics of Euthyneura for the first time, and is supplemented by the first microanatomical data. Surprisingly, both molecular and morphological features present compelling evidence for the common ancestry of ringiculid snails with the highly dissimilar Nudipleura—the most species-rich and well-known taxon of sea slugs (nudibranchs and pleurobranchoids). A new taxon name Ringipleura is proposed here for these long-lost sisters, as one of three major euthyneuran clades with late Palaeozoic origins, along with Acteonacea (Acteonoidea + Rissoelloidea) and Tectipleura (Euopisthobranchia + Panpulmonata). The early Euthyneura are suggested to be at least temporary burrowers with a characteristic ‘bubble’ shell, hypertrophied foot and headshield as exemplified by many extant subtaxa with an infaunal mode of life, while the expansion of the mantle might have triggered the explosive Mesozoic radiation of the clade into diverse ecological niches. The traditional gastropod subclass Euthyneura is a highly diverse clade of snails and slugs with at least 30,000 living species1,2.
