Resumen:
In South America, the family Philometridae is represented by several genera andspecies. In particular, Philometra and Philometroides are the most speciose genera. InArgentina, only Philometroides tahieli has been reported so far. The main objective ofthis study was to analyze the phylogenetic relationship between Ps. tahieli and otherSouth American philometrids using molecular data. The molecular analysis wasperformed using a female specimenof Ps. tahieli found on the opercular muscle of ajuvenile Micropogonias furnieri from brackish waters in Argentina. Phylogeneticrelationships were studied based on partial sequences of the 18S rDNA and 28S rDNAgenes. In the 18S rDNA tree, Ps. tahieli was mainly grouped with other Philometroidesfrom freshwater hosts from China, sharing the site of infection (head tissues ormuscles). In the 28S rDNA tree, obtained with fewer sequences, Ps. tahieli is relatedwith species on subcutaneous tissues of head. This study contributes with informationon philometrids and confirms the presence of different lineages among South Americanspecies, with Ps. tahieli representing a new one. Further studies on South Americanspecies using more molecular markers and new morphological characters will improveour knowledge of philometrid biodiversity and phylogeny.
