Box and whisker plots of measurements (mm) of morphological features of males of Amolops cremnobatus (B; n = 12), A. sengae sp. nov. (C; n = 5), and A. attiguus sp. nov. (E; n = 5). Measurements are snout-vent length (SVL), snout length (SNT), eye diameter (EYE), tympanum-eye distance (TEY), tarsus length (SHK), and foot length (FTL). Boxes show interquartile range and median (thick black line). Whiskers represent range up to 1.5 × interquartile range (IQR); dots show range beyond 1.5 × IQR. Clusters with the same symbol (* and †) are not significantly different, as determined by paired two-tailed t-tests following ANOVA.
