越南三线闭壳龟、中国三线闭壳龟和金头闭壳龟的新亚种（英文）

New Subspecies of Cuora cyclornata( Blanck,Mccord & Le,2006),Cuora trifasciata( Bell,1825) and Cuora aurocapitata( Luo & Zong,1988)

最近,遗传学研究证明了越南三线闭壳龟Cuoro cyclornata的有效性,并表明这个种内还存在第3个尚未描述的亚种,这个亚种也能从体色和形态量度上与以前认定的2个亚种相区分。同时,也证明中国三线闭壳龟C.trifasciata有一个来自中国海南岛在遗传学上存在歧化的种群。此现象也存在于金头闭壳龟C.aurocapitata,很久以来就发现该种有一个在体色量度上明显不同的种群,并得到了微卫星标记和形态学证据的支持。以上两种方法都显示了中国三线闭壳龟、越南三线闭壳龟和尚未描述的亚种之间的区别。为此,本文将这3个种群分别描述为新亚种C.cyclornata annamitica,C.trifasciata luteocephala和C.aurocapitata dabieshani。

Recent genetic studies have revalidated Cuora cyclornata and shown that a third,yet undescribed genetic subgroup which can be differentiated colorimetrically and morphometrically from the previously recognized 2 subspecies. Similarly for C. trifasciata a divergent genetic group was identified that can be clearly assigned to the specimens from Hainan Island,China. The same is true for C. aurocapitata where a colorimetrical well-distinguished variety has long been known,and this is supported by microsatellite markers（ Tiedemann et al.,2014） and by morphometrics. Here we use geometric morphological methods for the discriminant function analysis. Both the genetic results and the morphometric analysis of the shell clearly support the distinctiveness between C. trifasciata and C. cyclornata and the undescribed subspecies. These 3 groups are herein described as the new subspecies C. cyclornata annamitica,C. trifasciata luteocephala and C. aurocapitata dabieshani,respectively.
