Description
Este conjunto de datos contiene la evidencia molecular y los análisis filogenéticos de cinco nuevas especies de planarias terrestres (Geoplanidae) encontradas en áreas urbanas y periurbanas de Argentina (Buenos Aires, La Pampa) y Brasil (Rio Grande do Sul). Incluye alineamientos de secuencias de ADN del marcador mitocondrial Citocromo c Oxidasa subunidad I (Cox-1) para las nuevas especies (Paraparaba pampeana sp. nov., Paraparaba platense sp. nov., Pasipha silvanae sp. nov., Pasipha rara sp. nov. y Paraparaba santiaguense sp. nov.), junto con taxones de referencia (Dolichoplana, Endeavouria, Choeradoplana y otras especies de Pasipha). El conjunto de datos proporciona los archivos de salida de los análisis de delimitación de especies utilizando mPTP (multi-rate Poisson Tree Processes) y ASAP (Assemble Species by Automatic Partitioning), así como un árbol filogenético bayesiano inferido a partir de las secuencias alineadas. Estos datos refuerzan la identidad específica de las nuevas especies y destacan el potencial de biodiversidad de los hábitats antropizados. (2026-03-03)
This dataset contains the molecular evidence and phylogenetic analyses of five new species of land planarians (Geoplanidae) found in urban and peri-urban areas of Argentina (Buenos Aires, La Pampa) and Brazil (Rio Grande do Sul). It includes DNA sequence alignments of the mitochondrial marker Cytochrome c Oxidase subunit I (Cox-1) for the new species (Paraparaba pampeana sp. nov., Paraparaba platense sp. nov., Pasipha silvanae sp. nov., Pasipha rara sp. nov., and Paraparaba santiaguense sp. nov.) alongside reference taxa (Dolichoplana, Endeavouria, Choeradoplana, and other Pasipha species). The dataset provides the output files from species delimitation analyses using mPTP (multi-rate Poisson Tree Processes) and ASAP (Assemble Species by Automatic Partitioning), as well as a Bayesian phylogenetic tree inferred from the aligned sequences. These data reinforce the specific identity of the new species and highlight the biodiversity potential of anthropized habitats. (2026-03-03)

Notes

Nota sobre la disponibilidad de datos suplementarios:

De acuerdo con la política de publicación del artículo asociado, ciertos datos detallados requeridos para la máxima reproducibilidad y validación taxonómica se mantienen bajo embargo temporal hasta la publicación formal del manuscrito. Estos incluyen:

  • Ubicación geográfica exacta: Coordenadas GPS de los sitios de muestreo (necesarias para análisis biogeográficos).
  • Diagnóstico morfológico: Fotografías de especímenes vivos y preservados (necesarias para validación taxonómica externa).
  • Parámetros de reproducibilidad: Configuración detallada del software y registros de los análisis filogenéticos (necesarios para repetir exactamente el análisis).

Esta información estará disponible una vez que se publique oficialmente el artículo.

Note on Availability of Supplementary Data:

In accordance with the publication policy of the associated article, certain detailed data required for maximum reproducibility and taxonomic validation are held under temporary embargo until the formal publication of the manuscript. These include:

  • Exact Geographic Location: GPS coordinates of the sampling sites (necessary for biogeographic analyses).
  • Morphological Diagnosis: Photographs of live and preserved specimens (necessary for external taxonomic validation).
  • Reproducibility Parameters: Detailed software configuration and logs from phylogenetic analyses (necessary to exactly repeat the analysis).

This information will be available upon official publication of the article.

Representación gráfica de las particiones de especies generadas por el análisis ASAP. Cada fila corresponde a una secuencia (etiquetada con labelInAnalysis) y cada columna a una partición evaluada. Los números indican la asignación a grupos en cada partición. La partición óptima (menor score) se destaca generalmente con un recuadro o color. Este gráfico complementa los archivos scores_analisis_asap.csv y particiones_analisis_asap.csv.
