We have endeavored to define a new emerging digital genre in the world of Internet : netvertising. We present an analysis divided into two stages. An initial survey of 20 randomly selected netads reveals that texts in this genre are formed by very brief sentences and noun phrases, the systematic use of imperative and simple present tenses, second person personal pronouns, a higher use of punctu...

A comparative study of the female cibarial armature of New World CuZex, subgenera Mehnoconion, Aedinus, Anoed-Coporpa, BeZkinomyia, Car~oZZia, Micraedes and TinoZestes has been made. In addition, the female cibarial armature of species representing other New World taxa, including subgenera CUZex, Lutzia and Neocuzex and genera Gakhdomyia and Deinocerites was also examined for comparative purpos...

Prosopolepis Lutz is validated as a monotypic subgenus of Wyeomyia Theobald and the type species, Weomyia confusa (Lutz), is redescribed. The description includes illustrations of the male and female genitalia, the 4th-stage larva, and the pupa. Prosopolepis Jiui Bonne-Wepster and Bonne is resurrected from synonymy with Wy. confisa and recognized as the senior synonym of Wyeomyia kerri de1 Pont...

The monotypic Perdita subgenus Xeromacrotera Timberlake is currently known only from the male sex. Here, the female of Perdita (Xeromacrotera) cephalotes (Cresson, 1878) is associated, resulting in two new junior synonyms of P. (X.) cephalotes: Perdita (Procockerellia) excellens Timberlake, 1958, new synonym and Perdita (Cockerellia) autumnalis Timberlake, 1977, new synonym. The true number of ...

Scanning Electron Microscopic (SEM) study requires an expensive, complicated and timeconsuming method for sample preparation of aquatic invertebrates. In this paper a simplified sample preparation technique without dehydration, critical point dry, for SEM study of Bosmina tripurae was proposed. The present investigation included detail morphology of different life history stages of this cladoce...

The cliff fern family Woodsiaceae has experienced frequent taxonomic changes at the familial and generic ranks since its establishment. The bulk of its species were placed in Woodsia, while Cheilanthopsis, Hymenocystis, Physematium, and Protowoodsia are segregates recognized by some authors. Phylogenetic relationships among the genera of Woodsiaceae remain unclear because of the extreme morphol...

The internal transcribed spacer region (ITS) of nuclear ribosomal DNA was sequenced from 195 representative species of Allium, two species of Nothoscordum, and one species each of lpheion, Dichelostemma, and Tulbaghia. Within the Allium species the lengths of the ITS regions were in a range from 612 to 661 base pairs and pairwise genetic distances reached up to 46%. The ITS data supported the i...

The anther smut fungi in the ustilaginomycetous genus Antherospora (Floromycetaceae, Urocystidales) that infect monocots, are currently placed in nine species. Against the background of the generally observed high host specificity in smut fungi, the broad host range reported for some of the species suggests much higher diversity. Antherospora vaillantii s. lato includes anther smuts on differen...

The possibility of gene tree incongruence in a species-level phylogenetic analysis of the genus Ips (Coleoptera: Scolytidae) was investigated based on mitochondrial 16S rRNA (16S) and nuclear elongation factor-1 alpha (EF-1 alpha) sequences, and existing cytochrome oxidase I (COI) and nonmolecular data sets. Separate cladistic analyses of the data partitions resulted in partially discordant mos...

Celastrus and Tripterygium species, which are used in traditional Chinese medicine, have attracted much attention due to their anti-tumor promoting and neuroprotective activities, in addition to their applications in autoimmune disorders. However, systematic relationships between them and among species are unclear, and it may disturb their further medicinal utilization. In the present study, th...
