From the seven recognised subspecies of Stellagama stellio, S. s. vulgaris is found in northwestern Egypt and S. stellio salehi in the south Sinai and are known to be very similar. A Principal Component Analysis was carried out for 14 morphometric features, PCA1 accounted for a little cumulative variation (87.03%) between the two subspecies with a strong canonical correlation (r = 0.999). PCA2 accounted for a high cumulative variation (98.04%) with a strong canonical correlation (r = 0.985) and head height (HH) was the only major parameter for the significant difference. Within 398 sites of 16S rRNA gene sequenced, 6 base substitutions were recorded between S. s. vulgaris and S. s. salehi and the pairwise genetic divergence was calculated as 1.5%, which is comparable to that found between some other conspecific agamids. Neither the morphometric nor the molecular data support the distinction of two different subspecies. No genetic difference was found between S. s. salehi and S. s. brachydactyla which occurs from northern Sinai over Jordan to Saudi Arabia.

埃及 Stellagama stellio vulgaris 和 S. stellio salehi（爬行动物：Agamidae）之间的形态测量和分子差异

来自 Stellagama stellio 的七个公认亚种，S. s. vulgaris 在埃及西北部和西奈南部的 S. stellio salehi 中发现，并且已知非常相似。对 14 个形态特征进行了主成分分析，PCA1 占两个亚种之间的累积变异很小（87.03%），具有很强的典型相关性（r = 0.999）。PCA2 占高累积变异 (98.04%)，具有很强的典型相关性 (r = 0.985)，而头高 (HH) 是显着差异的唯一主要参数。在测序的 16S rRNA 基因的 398 个位点中，在 S. s. s. vulgaris 和 S. s. salehi 和成对遗传差异计算为 1.5%，与其他一些同种 amids 之间发现的差异相当。形态测量数据和分子数据都不支持区分两个不同的亚种。在 S. s. 之间没有发现遗传差异。萨利希和 S. s. brachydactyla，分布于西奈半岛北部，经约旦至沙特阿拉伯。
