Sequences of the nuclear internal transcribed spacer (ITS) regions ITS1 and ITS2 have been used widely in molecular phylogenetic studies because of their relatively high variability and facility of amplification. For phylogenetic applications, most researchers use sequence alignments that are based on nucleotide similarity. However, confidence in the alignment often deteriorates at taxonomic le...

Copepods belonging to the Oncaeidae family are commonly and abundantly found in marine zooplankton. In the Mediterranean Sea, forty-seven oncaeid species occur, of which eleven in the Gulf of Naples. In this Gulf, several Oncaea species were morphologically analysed and described at the end of the XIX century by W. Giesbrecht. In the same area, oncaeids are being investigated over seasonal and ...

Anopheles (Nyssorhynchus) marajoara Galvão & Damasceno (Diptera: Culicidae) is a memberof theAlbitarsis cryptic species complex and is aprimaryvectorofhumanPlasmodium inparts of Brazil. We report the Þrst record of An.marajoara in the department of Cochabamba and conÞrm its presence in the department of Santa Cruz, Bolivia. We also describe a PCR protocol producing a single amplicon ( 340 bp) o...

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 ident...
