A phenetic analysis is presented using SAHN clustering (UPGMA, simple matching coefficient). The resulting phenetic analysis is compared with the classification of Oxytropis as suggested by Bunge [2] and Vassilczenko [ll]. The results partly correspond with Bungean classification and suggest that there are basically four sections (Mesogaea, Oxytropis, Janthina, Eumorphu) which can be group...
Coetzeemyia, a new subgenus of Aedes Meigen (in the broad traditional sense, pre-Reinert 2000), is characterized and diagnosed. Aedes fryeri (Theobald) is removed from the subgenus Levua Stone and Bohart (genus Levua of Reinert et al. 2004) and placed in the new monotypic subgenus Coetzeemyia as its type species by present designation. Recognition of Coetzeemyia is based in part on a cladistic ...
Two convergences between subgenera of Bermudian land snails [P. (Poecilozonites) and P. (Gastrelasmus)] were initiated when a taxon of one subgenus evolved to the very different size range of the other. Entrance into this new size range produced or required a set of correlated changes in shape, color, and thickness that resulted in very precise convergences. Some of these ancillary changes were...
BACKGROUND Female sand flies of subgenus Adlerius are considered as probable vectors of visceral leishmaniasis in Iran. The objective of this study was to determine the morphological and genotypic variations in the populations of this subgenus in the country. METHODS Sand flies collected using sticky traps from 17 provinces during 2008-2010. The morphometric measurements were conducted with a...
Species of Culex (Melanoconion) Theobald are recognized as vectors of arboviruses. The species of this subgenus pose a real taxonomic challenge. The current classification of the subgenus recognizes a total of 160 species divided in two major sections, Melanoconion and Spissipes; and several non-formal groupings within each section. We gathered bibliographic records of the subgenus in South Ame...
-Twelve flavonoids (including seven flavonol and three flavone glycosides, one flavone aglycone, and one unknown) were isolated from the leaves of 198 populations of the seven species comprising Arnica subgenus Arctica. Flavonoid profiles are relatively simple, with two to six compounds found per population; however, considerable flavonoid variation was apparent in populations of A. angustifoli...
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.
