安徽省发现股鳞蜓蜥

Sphenomorphus incognitus Firstly Found in Anhui Province,China

2011年6～9月,在安徽岭南省级自然保护区采集到石龙子科蜓蜥属成体标本6号,卵一窝,窝卵数7,孵化后得幼体标本7号,经鉴定为股鳞蜓蜥(Sphenomorphus incognitus),系安徽省蜥蜴新纪录。标本保存于黄山学院动物标本馆。检视所采标本,发现如下变异:吻鳞凹陷;肛前鳞中间2枚显著大于外侧2枚;尾侧扁,尾中段高/宽的比值为1.49(1.23～1.71);体背褐色,有两列黑色斑点;成体和幼体尾部均褐色。此新纪录为研究股鳞蜓蜥的地理分布、形态变异和生态学提供了基础资料。

Six adults and seven larvae（ hatched from a clutch of eggs,clutch size 7） forest skink lizards were collected at Lingnan Nature Reserve,Huangshan,Anhui,China from June to September,2011. The thirteen specimens were identified as Sphenomorphus incognitus,a new lizard species record to Anhui Province. The specimens were deposited at the Museum of Huangshan University. After checking the 13 specimens,some variations were founded： rostral slightly concave; precloacals four,medial two enlarged sharply; tail slightly compressed,height /width of tail middle ratio ranging from 1. 23 to 1. 71（ Mean = 1. 49）; dorsum brown with two lines dark speckles; dorsal tail tip of adult and larva brown. The finding of this species in Anhui will benefit the further study on geographical distribution,morphological variation and ecology of S. incognitus.
