Cytogenetic variability in three species of the genus Cicindela (s.l.) (Coleoptera, Cicindelidae): karyotypes and localization of 18S rDNA genes Genet. Mol. Biol.
Proença,Sónia J. R.; Collares-Pereira,Maria João; Serrano,Artur R. M..
Three tiger beetle species from the Cicindelini tribe were examined cytogenetically and found to have the following karyotypes: Cicindela argentata, 2n = 18 + X1X2Y/X1X1X2X 2; Cicindela aurulenta, 2n=18 + X1X2X3Y/X1X1X 2X2X3X3 and Cicindela suturalis, 2n = 18 + X1X2X3X4Y/X1X 1X2X2X3X3X4X 4. Fluorescence in situ hybridization (FISH) using a PCR-amplified 18S rDNA fragment as a probe showed the presence of ribosomal clusters in two autosomes in C. argentata, two autosomes and two heterosomes in C. aurulenta and in two heterosomes in C. suturalis (male configuration), revealing two new patterns of rDNA localization. Such results are representative of the cytogenetic variability observed in the species rich genus Cicindela (sensu lato) mainly as regards the...

Studies on Tiger Beetles. CII. The Cicindelidae collected by Roland A. Müller in the Philippine Islands, with description of three new species (Coleoptera: Cicindelidae) Naturalis
Cassola, F..
The tiger beetles are discussed which have been collected by Mr Roland A. Müller (St. Gallen, Switzerland) in the course of his several expeditions to the Philippine Islands, together with a few more specimens from other sources. Distributional new data are provided for several interesting or poorly known species, and moreover three new species are described: Heptodonta mindoroensis spec. nov. from Mindoro Island, Lophyridia mindanaoensis spec. nov. from Mindanao, and Thopeutica (Thopeutica) rolandmuelleri spec. nov. also from Mindanao.

On occurrence, habitat specificity and natural history of adult tiger beetles (Coleoptera: Carabidae: Cicindelinae) near Manaus, Central Amazonia, and key to the larvae of tiger beetle genera Acta Amazonica
ADIS,Joachim; PAARMANN,Wilfried; AMORIM,Maristela A.; ARNDT,Erik; FONSECA,Claudio R. V. da.
Over a seven year period from 1991 to 1997, 22 species of tiger beetles, representing nine genera, were recorded near Manaus, Brazil. In the Whitewaterfloodplains along the Rio Solimões-Amazonas (Ilha de Marchantaria), three diurnal species inhabit inundation forests and six species (two diurnal, four nocturnal) live in open areas. Data on their natural history and adaptation to living conditions in floodplains are presented. Fifteen species were located on non-flooded uplands (Reserva Florestal A. Ducke). Five diurnal species inhabit the forest floor, two species are canopy dwellers, and eight species (seven diurnal, one nocturnal) live in open areas on whitesand or laterite. Only one species, Pentacomia lacordairei, was found in both floodplain and...

Spatial and temporal distribution of a tiger beetle guild (Coleoptera: Carabidae: Cicindelinae) along a 105m long transect in the reserva florestal A. Ducke near Manaus (Central Amazonia) Acta Amazonica
PAARMANN,Wilfried; ADIS,Joachim; LÜDECKE,Kirsten; TOBASCHUS,Nicole; FONSECA,Claudio R. V. da.
The spatial and temporal distribution of a guild of eight diurnal tiger beetle species was studied on a 105 m long transect near the field station of the Reserva Florestal A. Ducke near Manaus (AM), Brazil. The transect followed a path that included both shaded and an open areas. Five of the species, restricted to primary forest, occurrred only in shaded areas of the transect, and three species occurred in open areas. Of all eight species only two of the open habitat species showed no clear seasonality in adult activity. In six species the activity of adults was limited to the rainy season. The most pronounced annual rhythm was found in Pentacomia ventralis, an open habitat species. Activity of adults was limited to October/November. First in-star larvae...
