متن کاملTaxonomic relationship between two Gammarus species, G. nipponensis and G. sobaegensis (Amphipoda: Gammaridae), with description of a new species.
To assess the taxonomic relationship between G. nipponensis and G. sobaegensis, morphological features and molecular phylogenetic relationships using the nuclear 28S rRNA and the mitochondrial COI genes were examined. Detailed morphological observations revealed that G. nipponensis and G. sobaegensis were clearly distinguishable. In addition to the morphological differences, these two species w...

متن کاملA new species of the genus Gammarus (Crustacea: Amphipoda: Gammaridae) from the low salinity habitats in the northern Gulf of Mexico
In the northern Gulf of Mexico, Gammarus mucronatus sensu lato is represented by at least two forms, G. mucronatus sensu stricto and a less common “macromucronate” form, which appears to be restricted to low salinity habitats. These two forms have traditionally been separated using the size or angle of projection of the dorsal mucronations (processes). However, because of variability in the dev...
متن کاملEndevouridae, a review with description of four new species (Crustacea, Amphipoda, Lysianassoidea).
The family Endevouridae is reviewed and four new species from the two genera, Endevoura and Ensayara, are described from Australian and Japanese waters. All species are diagnosed and the type species of Endevoura (End. mirabilis Chilton, 1921) and Ensayara (Ens. ramonella J.L. Barnard, 1964), respectively, are redescribed and illustrated. A key to the 19 known world species of Endevouridae is p...
