FIGURE 4. Linear regressions of morphometric variables in L. cf. cataphracta and L. turi. All measurements are expressed in millimeter. A) Head length vs Minimum orbital diameter (L. cf. cataphracta: R2=0.33, p<0.0001; L. turi: R2=0.54, p<0.0001); B) Head length vs Internares distance(L. cf. cataphracta: R2=0.37, p<0.0001; L. turi: R2=0.65, p<0.0001); C) Standard length vs Post–dorsal distance (L. cf. cataphracta: R2=0.85, p<0.0001; L. turi: R2=0.97, p<0.0001); D) Standard length vs Post-anal distance (L. cf. cataphracta: R2=0.83, p<0.0001; L. turi: R2=0.95, p<0.0001).
