Three selective color pattern characters (DorBodPatrn, VenBodPatrn, and VenTalPatrn as montioned above) are scored across closely related Hemiphyllodactylus species in Tables 3 and 4. (Luu et al. 2025) Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data to their customers. These details, e.g. detailed descriptions or comparisons (about 6713 characters) are available for collaborators and contributors. Please contact us for details. |
