Table 3. Measurements of specimens of Potamotyrgon pantanensis analyzed in this study, including the holotype (A) MZUSP 110890. Mean (x) and Standard Deviation (SD) are expressed as proportions of disc width (% DW), and range is expressed in millimeters (mm) and proportion of disc width (% DW). Clasper measurements were taken only from adult specimens.
