摘　　要：关于睑虎属(Goniurosaurus)物种的研究主要集中在新种描述、分类分布以及系统进化等方面,繁殖生物学资料基本空白。本课题组于2017年9月至2019年8月对海南吊罗山国家级自然保护区内海南睑虎(G.hainanensis)的繁殖生物学特征进行了调查研究。结果发现,海南睑虎的繁殖期为3~10月,共观察到雌性个体147只,雄性个体179只。繁殖高峰期为7~8月,该段时间共观察到雌性96只,其中怀卵个体为51只,怀卵率为53%,怀卵数(1.9±0.5)枚,80%雌性个体的怀卵数为2枚,具有年产多窝卵的特性。卵均重、窝卵重、卵长径、卵短径、相对窝卵重1(窝卵重/产后母体体重)和相对窝卵重2[窝卵重/(产后母体体重+窝卵重)]与雌性体长无显著相关性。卵长径、卵短径和窝卵重与卵均重呈显著相关。孵化温度为22~26℃,孵化相对湿度为80%~95%,孵化周期为65~70 d(n=4),出壳过程持续近2 h(n=4)。吊罗山海南睑虎种群雌雄性比约为1︰1.2,成幼比约为8︰1,雌雄体型大小不存在两性异形。Studies on the reproductive biology of species Goniusrosaurus hainanensis was conducted first time from September 2017 to August 2019 basis on 147 of females and 179 males in the Diaoluoshan National Nature Reserve on Hainan Island.The breeding season of this species lasted from March to October but peaked in two months from July to August,respectively.The gravidity ratio of total females reached to 53% and the individual fecundity was 1.9±0.5 eggs,of 80% of females had 2 eggs.In addition,the females had the ability to produce multiple clutches per year.Egg size,clutch size,egg lengths,and egg widths did not significantly correlated with the reproductive characteristics and snout-vent lengths of female individuals.Egg incubation temperatures were 22-26℃,incubation humidity was 80%﹣95%,incubation periods were 65-70 d(n=4),and duration of the egg-breaking stage was lasted approximately 2 h(n=4).The ratios of females to males and adults to larvae were 1︰1.2 and 8︰1,respectively.There was no sexual dimorphism with respect to body size.
