HUERTAS RODRIGUEZ, C. K  e  ARRIETA VIOLETA, L. Taxonomic Revision of the Subgenus Daphnia and Hyalodaphnia (Daphnia genus) using Molecular Markers and Barcodes (COI). Ciencia en Desarrollo [online]. 2015, vol.6, n.1, pp.77-86. ISSN 0121-7488.

The objective of this review is to analyze some studies that clarify the taxonomic confusion about subgenera Hyalodaphnia y Daphnia of the genus Daphnia, through the studies with molecular markers and barcodes. The results were the following ones: the use of the gen COI allow to identify from specie of D. tenebrosa classified before, three provisionally different species, equally three species of D. pulex seems to form monophyletic lineages in Churchill, Manitoba, Canada. For the same gene in the complex D. pulex, it was obtained seven provisionally different species in the Argentina population. In the complex D. pulex in North America (Canada and United States) and Europe, using the ND5 gene nine provisionally different species were obtain, three of which were erroneously classified such as D. obtuse. For complex D. galeata, from the subgenus Hyalodaphnia through the analysis of the gene COI y 12S DNAr, were provisionally assigned four new species, also in the complex D. longiremis stood D. cristata. The study of the complex D. laevis in North America analyzing the variation of the allozymes and 12S and 16S DNAr genes, it allowed to discriminate five provisionally different species. However is recommended to realize more studies for confirming the confuse classification of the genus Daphnia.
