González Revelles Conclusiones A. El género Cephalota conforma un linaje basal dentro de los géneros de Cicindélidos ibéricos. La especie Jansenia chloropleura debería reclasificarse como constituyente de este género. B. Se proponen revisiones en la clasificación de algunos taxones, como el género Calomera o la especie Lophyridia chloris. C. Cicindela campestris y C. maroccana conforman un par de especies estrechamente relacionadas. Dentro de ambas se halla una fuerte correlación entre geografía y filogenia. D. El código de barras de ADN se revela como una herramienta válida para la identificación de estadíos larvarios, difíciles de asignar a taxones concretos utilizando los métodos tradicionales basados en la morfología.

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. HORN, 1914), comb, n., Probstia (gen. n.) triumphalis (W. HORN, 1902), comb. n. and Probstia triumphaloides (SAWADA & WlESNER, 1999), comb. n. Key Words: Coleoptera, Cicindelidae, Prothyma, Cylindera, Probstia, new genus, new combinations, tiger beetles. 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).

  • Localization and Activity of Rdna Genes in Tiger Beetles (Coleoptera: Cicindelinae)
    Heredity 74 (1995) 524—530 Received l7August 1994 The Genetical Society of Great Britain Localization and activity of rDNA genes in tiger beetles (Coleoptera: Cicindelinae) JOSÉ GALIAN*, JOSÉ SERRANO, PILAR DE LA RUA, EDUARD PETITP!ERREt & CARLOS JUANt Departamento de Biologia Animal, Facu/tad de Veterinaria, Universidad de Murcia, 30071 Murcia, Spain, tLaboratori de Genètica, Departament de Biologia Ambiental, Universitat de les I/los Ba/ears, 07071 Pa/ma do Mal/orca, Spain and 4Schoo/ of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, UK. Silverstaining of male meiotic nuclei of six species of the tiger beetle genus Cicindela (tribe Cicindelini), with multiple sex chromosomes, reveals the presence of active nucleolar organizing regions (NORs) in the sex vesicle. In one species, Cicindela melancholica, fluorescence in situ hybridization (FISH) with a ribosomal probe showed that rDNA genes are in one of the three X chromosomes and in the Y chromosome. Silver staining and FISH show that the related species Cicindela paludosa with a male XO system, has NORs located in one pair of autosomes. In Megacephala euphratica (tribe Megacephalini) these techniques indicate that NORs are located in three autosomal pairs but not in the single X chromosome of males. In all these species the nucleolus can be seen from the onset of meiosis to the end of the diffuse stage; it disappears from diplotene to the end of meiosis and appears again during the spermatid stage. From these results it is concluded that: (i) the nucleolus does not seem to play a major role in the pairing and association of the multiple sex chromosomes during first meiotic prophase and metaphase; (ii) the occurrence of NORs in the heterosomes of species having multiple sex chromosomes is thought to be an ancestral condition for the genus Cicindela; and (iii) changes of location of NORs from the heterosomes to the autosomes have occurred within species of this genus, at least in species showing extensive karyotypic repatterning.
