Wiesenborn 1 ABSTRACT .—Phoradendron coryae (Viscaceae) is a dioecious, parasitic plant on oak trees and shrubs in Quercus (Fagaceae), and it occurs from Arizona to Texas and into northern Mexico. The species produces minute spherical flowers during summer. Dioecious flowering requires pollinating insects to carry pollen from male to female plants. I investigated the pollination of P. coryae parasitizing Quercus turbinella shrubs at 3 sites at different elevations in the Cerbat Mountains of northwestern Arizona during August–September 2015. I examined pollen from male flowers, aspi - rated insects landing on female flowers, and counted conspecific pollen grains carried by insects.

  • A Review of the Beetles of Great Britain
    Natural England Commissioned Report NECR134 A review of the beetles of Great Britain The Soldier Beetles and their allies Species Status No.16 First published 20 January 2014 www.gov.uk/natural-england Foreword Natural England commission a range of reports from external contractors to provide evidence and advice to assist us in delivering our duties. The views in this report are those of the authors and do not necessarily represent those of Natural England. Background Making good decisions to conserve species should primarily be based upon an objective process of determining the degree of threat to the survival of a species. The recognised international approach to undertaking this is by assigning the species to one of the IUCN threat categories. This report was commissioned to update the threat status of beetles from the named families from work originally undertaken in 1987, 1992 and 1994 respectively using the IUCN methodology for assessing threat. It is expected that further invertebrate status reviews will follow. Natural England Project Manager - Jon Webb, [email protected] Contractor - Buglife (project management), K.N.A.

  • Telomeric DNA Sequences in Beetle Taxa Vary with Species Richness
    www.nature.com/scientificreports OPEN Telomeric DNA sequences in beetle taxa vary with species richness Daniela Prušáková1,2, Vratislav Peska3, Stano Pekár4, Michal Bubeník3, Lukáš Čížek1,2, Aleš Bezděk1 & Radmila Čapková Frydrychová1,2* Telomeres are protective structures at the ends of eukaryotic chromosomes, and disruption of their nucleoprotein composition usually results in genome instability and cell death. Telomeric DNA sequences have generally been found to be exceptionally conserved in evolution, and the most common pattern of telomeric sequences across eukaryotes is (TxAyGz)n maintained by telomerase. However, telomerase-added DNA repeats in some insect taxa frequently vary, show unusual features, and can even be absent. It has been speculated about factors that might allow frequent changes in telomere composition in Insecta. Coleoptera (beetles) is the largest of all insect orders and based on previously available data, it seemed that the telomeric sequence of beetles varies to a great extent. We performed an extensive mapping of the (TTAGG)n sequence, the ancestral telomeric sequence in Insects, across the main branches of Coleoptera. Our study indicates that the (TTAGG)n sequence has been repeatedly or completely lost in more than half of the tested beetle superfamilies. Although the exact telomeric motif in most of the (TTAGG)n-negative beetles is unknown, we found that the (TTAGG)n sequence has been replaced by two alternative telomeric motifs, the (TCAGG)n and (TTA GGG )n, in at least three superfamilies of Coleoptera. The diversity of the telomeric motifs was positively related to the species richness of taxa, regardless of the age of the taxa.

E-mail: [email protected] Abstract Axinotarsus pulicarius (F.), a soft-winged flower beetle native to the Palearctic Region, is newly reported from North America. More than 100 specimens were swept from vegetation, mostly from flower heads of velvetgrass, Holcus lanatus L., in Delta (Tsawwassen), British Columbia, Canada, in 2010 and 2011. This is the first record of the genus and species in the New World. Key words: Cleroidea, adventive species, British Columbia, description, diagnosis, distribution, new record Introduction Permanent settlement by Europeans in the early 17th century initiated major changes in the insect fauna of eastern Canada (Turnbull 1979; Morris 1983). Entomologists began to record adventive insects in Canada by the early 19th century (Majka & Klimaszewski 2008b). Studies by Brown (1940) and Lindroth (1957) stimulated research on immigrant insects (Majka & Klimaszewski 2008a), including detection, documentation of spread, analysis of pathways of entry, and assessment of economic and ecosystem consequences of their establishment.

  • Coleoptera: Melyridae) from Oman
    Studies and Reports Taxonomical Series 17 (1): 125-132, 2021 A new species of Brachyattalus Wittmer, 1988 (Coleoptera: Melyridae) from Oman Isidor S. PLONSKI1, Ali A.

The genus Brachyattalus Wittmer, 1988 (Melyridae: Malachiinae: Malachiini: Troglopina) is recorded from Oman for the first time. A new species, viz. Brachyattalus albovittatus sp.nov., is described and illustrated. Its distribution and ecology in the fog desert of central Oman are discussed. INTRODUCTION The genus Brachyattalus Wittmer, 1988 was erected for Attalusinus leveimpressus Wittmer, 1985 (typus generis) and seven other species (Wittmer 1988). Most of the latter ones were described or previously placed in the genera Attalus Erichson, 1840, Attalusinus Leng, 1918, Anexodes Abeille de Perrin, 1900, Calotroglops Abeille de Perrin, 1890, Carphuroides Champion, 1923, or Flabellattalus Pic, 1923. Two more species were subsequently described by Wittmer (1991, 1997). Wittmer (1988) wrote that Brachyattalus “should be placed next to Attalus” and that “it is a link between (…) [Attalus] and Attalusinus”. However, the genus Attalus in the widest sense is poly- and paraphyletic and in serious need of integrative taxonomic revision (cf. Gimmel et al. 2019). Furthermore, Attalusinus and Brachyattalus are currently classified as relatives of Troglops Erichson, 1840 (cf. Mayor 2007). The inclusion of two species is debatable: Wittmer (1988) placed Anexodes perrini Champion, 1922 with reservations (!) into Brachyattalus.
