四川省南部发现裸耳龙蜥种组一新种(爬行纲Reptilia: 鬣蜥科Agamidae: 飞蜥亚科Draconinae)

A new species of Mountain Dragon (Reptilia: Agamidae: Diploderma) from the D. dymondi complex in southern Sichuan Province, China

  • 摘要: 虽然在近10年间,学者对草绿龙蜥种组Diploderma flaviceps物种多样性不断开展了一系列的研究,但同属内其它广布物种确依旧鲜少得到学界的关注。结合形态和DNA分子数据,我们在此将分布于四川南部雅砻江流域下游,先前鉴定为裸耳龙蜥D. dymondi的龙蜥种群描述为一新种。该新种形态最接近于裸耳龙蜥和昆明龙蜥D. varcoae,然而其与后两者分子遗传距离甚远,并且拥有一系列稳定的形态鉴别特征,包括较长的颈鬣鳞、相对较小的鼓膜以及特殊的口腔颜色。此外,我们讨论了中国龙蜥属内可能存在的其他复合种。

     

    Abstract: Despite continuous studies on the cryptic diversity of the Diploderma flaviceps complex in Southwest China for the pastdecade, little attention has been given to other widespreadcongeners in China. Combining both morphological and phylogenetic data, we describe a new species of Diplodermafrom populations identified previously as D. dymondi in thelower Yalong River Basin in southern Sichuan Province. Thenew species is morphologically most similar to D. dymondiand D. varcoae, but it can be differentiated by a considerablegenetic divergence and a suite of morphological characters,including having taller nuchal crest scales, smaller tympana,and a distinct oral coloration. Additionally, we discuss otherputative species complexes within the genus Diploderma inChina.
