The Gallerucida singularis species group is established. Gallerucida gebieni Weise, status restored and G. haroldi Weise, status restored are resurrected from synonymy with G. singularis Harold. Lectotypes are designated for G. haroldiand G .tonkinensis Laboissi6èe. The species are differentiated mainly based on the structure of the endophallic sclerites.
The oak gallwasp Andricus coriarius is distributed across the Western Palaearctic from Morocco to Iran. It belongs to a clade of host-alternating Andricus species that requires host oaks in two sections of Quercus subgenus Quercus to complete its lifecycle, a requirement that has restricted the historic distribution and dispersal of members of this clade. Here we present nuclear and mitochondri...
The larvae of two cetoniine scarab beetles, Hoplopyga singularis (Gory and Percheron) from Brazil and Hologymnetis cinerea (Gory and Percheron) from Mexico, are described. The latter is the first description of a larva in this genus. Both of these species are included in a revised key to the larvae of New World Gymnetini (Scarabaeidae: Cetoniinae), which now includes ten species in eight genera.
طی نمونه برداریهایی که در سالهای 83-82 به منظور شناسایی حشرات گالزای بلوط در استان آذربایجان غربی انجام پذیرفت، دو نوع گال مختلف برای اولین بار از روی درختان بلوط Quercus libanii جمع آوری گردید. زنبورهای مولد گالهای جمع آوری شده بر اساس شکل ظاهری گالها شناسایی واسامی توسط دکترجورج ملیکا از آزمایشگاه سیستماتیک پارازیتوییدها تایید نهایی شد. گونه های زنبورمولد این گالها عبارتند از : 1- An...
Euglossella, one of the most distinctive subgenera of orchid bees of the genus Euglossa, is composed of two characteristic assemblages of species, one of them comprising bees bearing the strongly metallic integument trademark of the genus (viridis species group), and the other consisting of bees with a brown integument shaded with metallic iridescence (decorata species group). Here we provide t...
The male of Leuctra costai (Aubert, 1953) is redescribed. In all specimens studied, we noted the presence of two sclerotized processes in the tenth urosternite (not reported in any other Leuctra species) and the presence of lateral sclerotized processes on the last four abdominal segments (previously cited only in Leuctra moreae, Zwick, 1978). These characters, which were not mentioned nor illu...
In order to explain the durability of the Moraceae plant family, phytochemistry of Bagassa guianensis was performed. Ethyl acetate extract was obtained from the heartwood and 18 secondary metabolites were isolated, including 6 moracins [6-O-methyl-moracin M, 6-O-methyl-moracin N and moracin Z; previously identified: moracin M, moracin N and moracin P], 8 stilbenoids [presently identified: (-)-e...
Three major hypotheses have been advanced for the adaptive nature of plant galls: nutrition, enemyavoidance, and microenvironment. Of these, the microenvironment hypothesis has been frequently invoked, but rarely tested directly. We tested this hypothesis in a population of Andricus quercuscalifornicus (Bassett) (Hymenoptera: Cynipidae) wasps inducing galls on Quercus lobata Née (Fagaceae) tree...
