Statistics showing differences in the length of the carapace anterior edge in subfamily Hadrurinae based on the following morphometric ratio: anterior_edge_length / median_tubercle_position. See Fig. 17 for methods of measurement. Data shows that the anterior edge of Hoffmannihadrurus is approximately 48 % longer than in Hadrurus. Large standard error range separation and a very small p-value from variance analysis further support the significant statistical difference between the two genera. Statistical data group: minimum–maximum (mean) (±SDEV) [N] {standard error range} (coefficent of variability). * Mean value difference, standard error range separation, and analysis of variance. Statistical data derived from specimens examined and the following references: Williams (1970), Stahnke (1971), Soleglad (1976), and Fet et al. (2004).
