As a part of ongoing cytogenetic studies on the jewel-beetles (Buprestidae, Coleoptera) of Armenia, the male karyotypes and meiosis of nine species (5 genera, 4 tribes, 2 subfamilies) are described, figured and discussed. In Ovalisia nadezhdae Sem., Sphenoptera artemisiae Reitt., Coraebus rubi L., C. sinuatus Creutz., Meliboeus caucasicus Reitt., Agrilus angustulus Ill. Men., A. obscuricollis K...

New Philippine Coraebini (Coleoptera: Buprestidae) are described: one new genus, Visayasella, gen. nov., is erected for two new species: the type species Visayasella superba sp. nov. from Leyte and V. gracilis sp. nov. from Negros. The new genus is contrasted to the genera Obenbergerula Strand 1932 (= Böttcheria Hoscheck 1931) and Sibuyanella Obenberger 1942 in a table of character states. Four...

Differential phase optical low coherence reflectometry (OLCR) was used to detect sub-wavelength displacements in the infrared-sensitive thoracic pit organ of Melanophila acuminata (Coleoptera: Buprestidae) upon absorption of infrared radiation at 3.39 microm. The displacement had more complex morphology but similar amplitude ( approximately 100 nm at 1 W cm(-2)) when compared to the displacemen...

Introduction Invasive alien species can have devastating consequences on native biodiversity, ecosystem and evolutionary processes (Lovett et al. 2006, McNeely 2001, Mooney and Cleland 2001). In the United States alone, economic costs associated with environmental damages and losses as a result of invasive species have been estimated to total between $120-137 billion per year (Pimentel et al. 2...
