Several members of the dipteran family Tephritdae are serious pests because females lay eggs in ripening fruit. The genus Bactrocera is one of the largest within the family with over 500 described species arranged in 28 subgenera. The phylogenetic relationships among the various species and subgenera, and the monophyly of specific groups have not been examined using a rigorous phylogenetic anal...

Two new species of the genus Euglossa Latreille, subgenus Glossurella Dressler are here presented. Euglossa (Glossurella) emberasp. n., from the Pacific lowlands of Colombia, and Euglossa (Glossurella) adiastolasp. n., from the Atlantic Forest of Brazil. Their taxonomic association and distinction are discussed, as well as the correct understanding of the subgenus Glossurella.

Two new species of the genus Empis subgenus Lissempis Bezzi, 1909 are described from the Caucasus: Empis (Lissempis) azishtauensis sp. nov. (Russia: Adygea, Krasnodar Territory) and E. (L.) krasnodarensis sp. nov. (Russia: Krasnodar Territory). An updated key to European species of the subgenus is given.

Two new carabid beetle species, Pterostichus (Aphaonus) mariamae sp. nov. and Pterostichus (Aphaonus) svetlanae sp. nov., related to an enigmatic mountainous representative of the subgenus Aphaonus, P. (Aphaonus) arcanoides Lorenz, 1998, are described from the Abkhazian midlands (Tsebelda Plateau and Mtsara district). Discriminative features of the new species in the subgenus are briefly discus...

Chromosomal localization of ribosomal RNA coding genes has been studied by using FISH (fluorescence in situ hybridization) in 21 species from the genus Chironomus Meigen, 1803. Analysis of the data has shown intra- and interspecific variation in number and location of 5.8S rDNA hybridization sites in 17 species from the subgenus Chironomus and 4 species from the subgenus Camptochironomus Kieffe...

It has recently been discovered that the Alcohol dehydrogenase and Alcohol dehydrogenase-related genes of Drosophila melanogaster and closely related species constitute a single transcription unit and that the Alcohol dehydrogenase-related gene is exclusively expressed from a dicistronic mRNA. Here, we show that in Drosophila lebanonensis, subgenus Scaptodrosophila, Adhr: is also transcribed as...

The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...

The genus Cyperus with five subgenus and 29 species, is the second largest genus of Cyperaceae family in flora of Iran. In this research, stem and leaf anatomy of 10 species belonging to subgenus Cyperus is investigated. The stems in transverse section of all examined species were triangular except for C. bulbosus which was subterete to polygonal. The ground tissue was spongy with numerous and ...

Two new species of the Macropsinae leafhopper subgenus Pediopsoides (Pediopsoides) Matsumura, 1912, Pediopsoides (Pediopsoides) damingshanensis Li, Dai & Li, sp. n. and Pediopsoides (Pediopsoides) tishetshkini Li, Dai & Li sp. n., are described and illustrated from Guangxi Province of southern China. A key to males is provided to distinguish the species of the subgenus along with a map showing ...
