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 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 Jan 1997

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

Department of Plant Pathology: Faculty Publications

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 Internal Transcribed Spacer Region Of Belonolaimus (Nemata: Belonolaimidae), T. Cherry, A. L. Szalanski, T. C. Todd, Thomas O. Powers Jan 1997

The Internal Transcribed Spacer Region Of Belonolaimus (Nemata: Belonolaimidae), T. Cherry, A. L. Szalanski, T. C. Todd, Thomas O. Powers

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 …
