Table S4. PCA loadings of 21 log-transformed measurements from: H. aquila sp. nov., H. falcatus sp. nov., H. curvidens sp. nov., and H. squamipinnis. Results illustrated in Fig. 3d. Abbreviations: SL = standard length; HL = head length; BD = body depth; PrD = predorsal distance; PrA = preanal distance; PrP = prepectoral distance; PrV = prepelvic distance; DFB = dorsal fin base length; AFB = anal fin base length; CPL = caudal peduncle length; CPD = caudal peduncle depth; HW = head width; ED = eye diameter; IOW = interorbital width; SnL = snout length; LaD = lachrymal depth; ChD = cheek depth; PPL = premaxillary pedicel length; UJL = upper jaw length; LJL = lower jaw length; LJW = lower jaw width.
