A. Morphometric measurement methodology for species within the genus Beaufortia: 1 - Standard length (SL); 2 - Eye diameter (ED); 3 - Gill slit length (GSL); 4 - Pectoral fin base length (PBL); 5 - Head length (HL); 6 - Body depth (BD); 7 - Dorsal fin base length (DBL); 8 - Anal fin base length (ABL); 9 - Post-anal fin length (PoAL); 10 - Caudal peduncle length (CL); 11 - Caudal peduncle depth (CD); 12 - Head length (HL); 13 - Snout Length (SnL); 14 – Head width (HW); 15 - Interorbital distance (IOD); 16 - Distance between nostrils (ND); 17 - Pre-dorsal Length (PrDL); 18 - Pectoral fin disc length (PL); 19 - Head width at pectoral fin origin (HWPO); 20 - Mouth slit width (MW); 21 - Pectoral fin disc width (PW); 22 - Body width (BW); 23 - Pelvic fin disc width (PvW); 24 – Pre-pectoral length (PrPL); 25 – Pre-pelvic length (PrPvL); 26 - Pelvic fin disc length (PvL); 27 - Pre-anal pore length (PrApL); 28 - Pre-anal fin length (PrAL); B. The last branched anal-fin and dorsal-fin rays located on the last complex pterygiophore were counted as a single ray.
