PREMISE OF THE STUDY Artemisia subgenus Tridentatae plants characterize the North American Intermountain West. These are landscape-dominant constituents of important ecological communities and habitats for endemic wildlife. Together with allied species and genera (Picrothamnus and Sphaeromeria), they make up an intricate series of taxa whose limits are uncertain, likely the result of reticulate...

The taxonomy of the weevils inhabiting male cycad cones in the New World is reviewed. All species belong in a single subtribe, Allocorynina, of the family Belidae, subfamily Oxycoryninae and tribe Oxycorynini and are known to develop only in cones of the cycad genera Dioon and Zamia. Most species of Rhopalotria Chevrolat develop in male cones of Zamia ranging from Mexico, Belize, the Caribbean ...

The taxonomic status of the subgenera of Lepidocyrtus Bourlet is confused. Currently ten subgenera are recognised but their separation, using the existing set of diagnostic characters, is not clear. Collections over the last forty years have shown that species of Setogaster Salmon, originally described as a genus (Trichogaster Handschin) and currently considered a subgenus of Lepidocyrtus, are ...

BACKGROUND AND AIMS Studying the genome structure of pines has been hindered by their large genomes and uniform karyotypes. Consequently our understanding of the genome organization and evolutionary changes in different groups of pines is extremely limited. However, techniques are now available that can surmount these difficulties. The purpose of this study was to exploit some of these techniqu...

The genus Omophorus Schoenherr, 1835 is recorded for the first time from the Oriental Region and a new subgenus and species, Omophorus (Sinomophorus subgen. n.) rongshusp. n. is described from Yunnan province (P.R. China). The new subgenus differs from the subgenus Omophorus by the longer antennal club, the bifid vestiture of the ventral parts, the elongate subtrapezoidal scutellum, the very sm...

Application of the polymerase chain reaction (PCR) method for detection of subgenus B adenoviruses (types 3, 7 and 11) was investigated. It is based on a simple (nonnested) PCR using primer pairs specific for the hexon-coding region. The PCR allowed amplification of DNA from subgenus B adenovirus prototype strains (types 3, 7 and 11) and adenovirus isolates (types 3 and 7), whereas it did not a...

The fiddler crab Uca formosensis Rathbun, 1921 (Crustacea: Decapoda: Ocypodidae), restricted to the western part of Taiwan and the offshore Penghu (Pescadores) Islands in the Taiwan Strait, has been placed under the subgenus Uca (Gelasimus) Latreille, 1817 (= Uca (Thalassuca) Crane, 1975) based on only less than a dozen specimens, but later suggested under the subgenus Tubuca Bott, 1973 because...

The subgenus Choeras Mason, 1981 of genus Apanteles Foerster, 1862 (Hymenoptera, Braconidae, Microgastrinae) from China is revised with 18 new species described and illustrated, and one known species redescribed. A key to the Chinese species of this subgenus is provided.

Fore new species of Stegana (Steganina) ornatipes species group are found from Yunnan, China: S. (S.) angustifoliacea sp. nov., S. (S.) crinata sp. nov., S. (S.) nigripes sp. nov. and S. (S.) polysphyra sp. nov. The DNA sequences of the mitochondrial COI gene with BOLD Process ID and GenBank accession numbers are provided for the Chinese species. 

a new and distinctive form belonging to the genus and subgenus eremias fitzinger, 1834 is reported from the highlands of alvand mountains, hamedan province, western iran at about 2700 m elevation. it is easily distinguished from all the other species of the typical subgenus (e. velox, e. persica, e. strauchi, e. nigrolateralis, e. lalezharica, e. afghanistanica, e. regeli, e. suphani, and e. ni...
