Table 1 Evaluation on the meristic and mensural characters measured for 38 Bungarus fasciatus individuals from Java (JV), Mizoram (MZ), and West Bengal (WB), including mean, standard deviation, minimum and maximum values. Standardized meristic data were utilised for the following tests: Ve of JV and MZ was tested for inter-population difference and sexual dimorphism using separate one-way ANOVA with locality and sex as the factors, respectively; Sc of JV and MZ was tested using two-way ANCOVA using sex and locality as factors; BB and NBW were tested for inter-population difference (among the three populations) and sexual dimorphism (within JV and MZ) using separate one-way ANOVA with locality and sex as the factors, respectively; since BT violated the assumption of homoscedascity, it was tested using the alternative Brown-Forsythe test and was indicated by octothorp (#). For mensurals, two-way ANCOVA was performed for the log transformed TaL, HL, and HW values from JV and MZ by using the log transformed SVL as a covariate, with locality and sex as the factors. The characters with statistically significant variations at the alpha level of 0.05 are shown in boldface. The characters tested for inter-population difference across the three populations are indicated by asterisk (*).
