Taxonomic Notes On Amblycerus Thunberg, 1815 (Coleoptera: Bruchidae), John M. Kingsolver, Cibele S. Ribeiro-Costa
Taxonomic Notes On Amblycerus Thunberg, 1815 (Coleoptera: Bruchidae), John M. Kingsolver, Cibele S. Ribeiro-Costa
Insecta Mundi
The following changes in nomenclature of some species of Amblycerus Thunberg, 1815, are proposed: A) Elevated to new taxonomic status-A. insuturatus (Pic, 1902) from (Spermophagus subflavidus var. insuturatus); A. luteolineatus (Pic, 1929) from (Spermophagus luteonotatus var. luteolineatus); A. paulonotatus (Pic, 1906) from (Spermophagus luteonotatus var. paulonotatus). B) New synonmy-A. dispar (Sharp, 1885)(= Spermophagus longissimus Pic, 1902; =S. caryoboriformis Pic, 1910; = S. guyanensis Pic, 1917; S. piceosuturalis Pic, 1927; =S. caracasensis Pic, 1954); A. gounellei (Pic. 1902)(= S. eurtus Pic, 1911; =S. basipennis Pic, 1936); A. insuturatus (Pic, 1902)(= …

The Larva, Pupa And Female Of Agapetus Jocassee Morse (Trichoptera: Glossosomatidae), Jason S. Craft, John C. Morse
Publications
Agapetus jocassee is a "Species of Concern" on the lists of the U.S.D.I. Fish and Wildlife Service because it is known from only three streams of the Lake Jocassee catchment in Oconee and Transylvania counties, South and North Carolina. To assist in solving identification problems and to contribute to knowledge of the distribution of this species, larvae and pupae of A. jocassee were collected from mountain streams in North and South Carolina, reared to adulthood and identified. The larva, pupa, and female of the species are described for the first time. Characters were found in those ontogenetic stages that distinguish …
The Rdna Internal Transcribed Spacer Region As A Taxonomic Marker For Nematodes, Thomas O. Powers, T. C. Todd, A. M. Burnell, P. C. B. Murray, C. C. Flemming, Allen L. Szalanski, B. A. Adams, T. S. Harris
The Rdna Internal Transcribed Spacer Region As A Taxonomic Marker For Nematodes, Thomas O. Powers, T. C. Todd, A. M. Burnell, P. C. B. Murray, C. C. Flemming, Allen L. Szalanski, B. A. Adams, T. S. Harris

The ITS region from a wide taxonomic range of nematodes, including secernentean and adenophorean taxa, and free-living, entomopathogenic, and plant-parasitic species, was evaluated as a taxonomic marker. Size of the amplified product aided in the initial determination of group membership, and also suggested groups that may require taxonomic reevaluation. Congeneric species often displayed identically sized ITS regions, but genera such as Pratylenchus and Tylenchorhynchus had species with large differences in size. ITS heterogeneity in individuals and populations was identified in several nematode taxa. PCR-RFLP of ITS1 is advocated as a method of taxonomic analysis in genera such as Helicotylenchus that …
The Linnaean Hierarchy And The Evolutionization Of Taxonomy, With Emphasis On The Problem Of Nomenclature, Kevin De Queiroz
The Linnaean Hierarchy And The Evolutionization Of Taxonomy, With Emphasis On The Problem Of Nomenclature, Kevin De Queiroz
Aliso: A Journal of Systematic and Floristic Botany
During the post-Darwinian history of taxonomy, the Linnaean hierarchy has maintained its role as a means for representing hierarchical taxonomic relationships. During the same period, the principle of descent has taken on an increasingly important role as the basis for reformulated versions of fundamental taxonomic concepts and principles. Early in this history, the principle of descent provided an explanation for the existence of taxa and implied a nested, hierarchical structure for taxonomic relationships. Although an evolutionary explanation for taxa contradicted the Aristotelian context within which the Linnaean hierarchy was developed, the nested, hierarchical structure of taxonomic rela· tionships implied by …

Belonolaimus isolates from six U.S. states were compared by restriction endonuclease digestion of amplified first internal transcribed spacer region (ITS1) of the nuclear ribosomal genes. Seven restriction enzymes were selected for evaluation based on restriction sites inferred from the nucleotide sequence of a South Carolina Belonolaimus isolate. Amplified product size from individuals of each isolate was approximately 700 bp. All Midwestern isolates gave distinct restriction digestion patterns. Isolates identified morphologically as Belonolaimus longicaudatus from Florida, South Carolina, and Palm Springs, California, were identical for ITS1 restriction patterns. The correlation between ITS1 restriction patterns and the distribution of B. longicaudatus isolates …
Taxonomic Status And Biogeography Of The Southern Bog Lemming, Synaptomys Cooperi, On The Central Great Plains, Gregory M. Wilson, Jerry R. Choate
Taxonomic Status And Biogeography Of The Southern Bog Lemming, Synaptomys Cooperi, On The Central Great Plains, Gregory M. Wilson, Jerry R. Choate

We assessed geographic and nongeographic variation among populations of the southern bog lemming (Synaptomys cooperi) in Arkansas, Iowa, Illinois, Kansas, Missouri, Nebraska, and South Dakota based on morphological data. Univariate and multivariate analyses of 15 cranial characters revealed no consistent sexual dimorphism. Geographic variation in cranial morphology of adults varied clinally, with individuals increasing in size from north to south and east to west. The largest individuals overall were from southwestern Kansas (S. c. paludis) and southwestern Nebraska (S. c. relictus), and the smallest individuals were from populations in eastern Illinois (S. c. gossii). We found only minor steps in …
