Abstract

The Bedriaga's Plate-tailed Gecko, Teratoscincus bedriagai, Nikolsky, 1900 is distributed in the northern and eastern deserts of Sistan, Iran and the desert regions of southern Afghanistan. In this research, the male reproductive cycle of this lizard has been studied from 5 April to 5 August, 2013. Totally, 40 adult males were collected by hand at midnight from four adjacent stations in Damghan County, Semnan Province of Iran. Most of the lizards were observed on highly saline, loose soil covered with a thin salt crust, and were common near Tamarix bushes. Animals were transferred to the laboratory and their morphometric characters were measured. After anesthetizing the animals, their testes were removed and processed for morphometric and histological studies. Results showed that the spermatogenesis started after hibernation from early April and ended in August. The peak of spermatogenesis was in May. The numbers of seminiferous tubules were 24-75 and their diameter varied between 72.50 and 232.50 microns. The diameter of tunica albuginea varied between 3.05 and 8.20 microns and diameter of germinal layer varied between 20.40 and 124.30 microns. Spermatogenesis of T. bedriagai in Iran is seasonal and alternates with associate type.

伊朗板尾壁虎(Teratoscincus bedriagai)雄性生殖周期
贝德里亚加板尾壁虎,Teratoscincus bedriagai, Nikolsky, 1900,分布在伊朗锡斯坦北部和东部沙漠以及阿富汗南部沙漠地区。在这项研究中,从2013年4月5日到8月5日,研究了这种蜥蜴的雄性生殖周期。午夜时分,在伊朗塞姆南省Damghan县的四个相邻站点,共手工收集了40名成年男性。大多数蜥蜴被观察到在高盐、覆盖着薄盐壳的松散土壤上,在柽柳灌木附近很常见。动物被转移到实验室,并测量其形态计量特征。麻醉动物后,取下它们的睾丸,进行形态计量学和组织学研究。结果表明:冬虫夏草的精子发生始于4月初,结束于8月。精子发生高峰出现在5月。精小管数量为24 ~ 75个,直径为72.50 ~ 232.50 μ m。白膜直径为3.05 ~ 8.20 μ m,生发层直径为20.40 ~ 124.30 μ m。在伊朗,黄毛瓢虫的精子发生是季节性的,并与伴生型交替发生。
