摘要
2011年5月—2013年3月,在实验室饲养条件下对采自墨江和腾冲两地红瘰疣螈的成体外形结构进行比较。结果表明,腾冲个体的颜色较黑,而墨江个体的颜色鲜艳,体色为橘黄色;腾冲个体平均体长为151.80mm,墨江个体平均体长为134.32mm;腾冲个体尾长与体长比为0.489,墨江个体尾长与体长比为0.479;两地红瘰疣螈背部及体侧均有不规则的黑色疣粒,其中,腾冲个体背部两侧的瘰疣大小形状相同,墨江个体的瘰疣形状不规则,大小有差异,而且,墨江个体的疣粒较腾冲的更密集,更显著;在第二性征方面,腾冲红瘰疣螈雄性泄殖孔平均长度为8.2mm,墨江红瘰疣螈雄性泄殖孔平均长度为7.7mm。
The shape structure of adult Tylototriton shanjing collected from Mojiang and Tengchong were compared under laboratory feeding conditions from May of 2011 to March of 2013 . The results showed that Tengchong individuals had blacker color, Mojiang individuals had saffron yellow skin. The average body length of Tengchong individuals and Mojiang individuals were 151.80 mm and 134.32 mm respectively. The ratio of tail length to body length of Tengchong individuals and Mojiang individuals were 0.489 and 0.479 respectively. There were irregular black knobby on the back and body side of Tengchong individuals and Mojiang individuals. The knobby size and shape on the both sides of back in Tengchong individuals were the same, while the knobby of Mojiang individuals had irregular shape and different size. And the knobby of Mojiang individuals was more intensive and remarkable than Tengchong individuals. As for the secondary sexual characteristics, the average cloaca length of male Tengchong individuals was 8.2 mm and that of male Mojiang individuals was 7.7 mm.
