Geometric morphometric on a new species of Trichodinidae. : A tool to discriminate trichodinid species combined with traditional morphology and molecular analysis
This study reports a new Trichodinidae, Trichodina bellottii n. sp., parasitizing the pearly fish Austrolebias bellottii from Buenos Aires, Argentina. Its small subunit ribosomal ribonucleic acid (SSU rDNA) was sequenced for the first time. Based on the results from morphological identification, SSU...

| Sumario: | This study reports a new Trichodinidae, Trichodina bellottii n. sp., parasitizing the pearly fish Austrolebias bellottii from Buenos Aires, Argentina. Its small subunit ribosomal ribonucleic acid (SSU rDNA) was sequenced for the first time. Based on the results from morphological identification, SSU rDNA sequencing, and Elliptical Fourier analysis, the new species was identified and compared with similar species. Phylogenetic analysis revealed that the genetic distances among the new species and similar species reached interspecific levels, furthermore, the phylogenetic study also validated the identification of T. bellottii n. sp. and its placement in the genus Trichodina. To be able to quantitatively describe the differences in shapes with similar species, this study used the elliptic Fourier analysis by first time in this genus. |
