Der Deutsche Sandlaufkäfer Cylindera Germanica (Linnaeus, 1758) Im Landkreis Lichtenfels (Oberfranken / Bayern) ©Gesellschaft für Angewandte Carabidologie e.V. download www.laufkaefer.de Der Deutsche Sandlaufkäfer Cylindera germanica (Linnaeus, 1758) im Landkreis Lichtenfels (Oberfranken / Bayern) Michael-Andreas FRITZE, Alexander KROUPA und Wolfgang LORENZ Abstract: The German Tiger Beetle Cylindera germanica (Linnaeus, 1758) in the county of Lichtenfels (Upper Frankonia / Bavaria / Germany). - The German Tiger Beetle Cylindera germanica is a species facing extinction, not only in Bavaria but also all over Germany. Populations of this beetle declined dramatically during the last century as a result of inappropriate land use. Today it is known at only a few sites. In Bavaria the largest concentration of this species can be found in the region of Lichtenfels in Upper Franconia, where many populations, some of them with a large number of individuals, can be charted. The local government therefore has a responsibility for the protection of this tiger beetle. 1 Einleitung damit zum Verschwinden der Art.

Four patterns of rDNA localization in these tiger beetles were found: 1. Two clusters located in one autosomal pair; 2. Two clusters located in one autosomal pair and one in an X chromosome; 3.

On four presumed "Prothyma" species from China and the Oriental region (Coleoptera: Cicindelidae) Fabio CASSOLA Abstract Based on examination of male genitalia and other morphological features, the true taxonomic placement of four poorly known species incorrectly placed in the genus Prothyma HOPE, 1838, is established: Cylindera (Cylindera) lautissima (DoiCHTOUROFF, 1888), comb, n., Cylindera (Cylindera)pseudocylindriformis (W.

Zusammenfassung Basierend auf der Untersuchung von männlichen Genitalien und anderen Körpermerkmalen wurde für vier wenig bekannte, irrtümlich in die Gattung Prothyma HOPE, 1838, plazierte Arten die richtige taxonomische Stellung geklärt: Cylindera (Cylindera) lautissima (DOKHTOUROFF, 1888), comb, n., Cylindera (Cylindera) pseudocylindriformis (W.

Introduction The tiger beetle genus Prothyma HOPE, 1838 (= Euryoda LACORDAIRE, 1843), type genus of the cicindeline subtribe Prothymina W. HORN, 1910, was first reviewed by RlVALlER (1964), who re-defined the entire genus based on new characters, such as the peculiar architecture of the inner sac of male aedeagus. His revision resulted in the resurrection of several genera {Megalomma WESTWOOD, 1842, Peridexia CHAUDOIR, 1860, Physodeutera LACORDAIRE, 1843,OxygoniolaW.HORN, 1892, VataFAVVEL, 1903,Euryarthron GuÉRlN, 1849, Rhytidophaena BATES, 1891) which had been unduly linked to Prothyma by HORN (1926).

    SPRINGS AND SEEPAGES - Sheet 5 Managing springs and seepages on coastal cliffs Springs and seepages are important for coastal cliff invertebrates. Over half of the species restricted to soft cliffs in the UK are associated with freshwater micro-habitats1. A range of freshwater habitats are provided by groundwater seepages on cliffs, from spring-fed streams to mossy trickles to damp ground, pools, swamp and carr. The mobile nature of eroding soft cliffs means that the full range of vegetation succession is present on many sites - ranging from wet bare ground to reedbed.
