Table of all specimens used for the present study with the assignment of each specimen to its corresponding species described herein.

Information regarding specimen assignment to genetic and genomic deep lineages, specimens used as type material, geographic location, elevation, 12S accession numbers, MorphoBank accession codes, as well as information on which individuals were included in each morphological, genetic, genomic and geographic dataset are provided. Genomic dataset1 and dataset2 include all specimens used for genomic analyses (Genomic column) except P. flavipuntatus specimens; Genomic dataset3 includes all specimens used for genomic data; Specimens selected for dataset4 are highlighted in bold in the Genomic column. Holotype (H) and paratype (P) museum codes refer to the following collections: IBE[X]: field series of S. Carranza housed at the Institute of Evolutionary Biology (CSIC-UPF); ZFMK[X]: Zoologisches Forschungsmuseum Alexander Koenig, Bonn, Germany; NHMOK[X]: the Naturhistorisk Museum, Oslo, Norway; MZB [X]: Museu de Ciències Naturals de Barcelona, Spain.
