Abstract:A survey on reproduction of Vibrissaphora leishanensis was conducted in Leigongshan National Nature Reserve from October, 2014 to June, 2016. The results suggested that the reproduction period of this toad started from the end of September through December and peaked in the middle of November. Body mass and length of males were greater than those of females. Reproduction process was composed of nesting, croaking for courtship, mating and oviposition. Males croak individually and mating initiatively. Mating and ovipositing of multiple couples were observed in the same site. Diameter of egg masses were 65.13-100.47 mm with mean of 77.73 mm±9.47 mm (n=54). The observed clutch size was about 162-394 eggs, and the mean (±SD) clutch size was 226.79±7.89 (n=54). Ovum diameter ranged from 2.06 mm to 5.18 mm with mean 3.82 mm±0.91 mm(n=270). Embryonic development lasted 107-157 days (mean 127.71±7.38, n=54) in the field.
