The "Linh Duong" (Pseudonovibos spiralis), a newly described Vietnamese bovid, has been shown to be related to the Caprinae on the basis of the mitochondrial cytochrome b gene sequencing from horn fragments. To integrate the greatest available biodiversity we performed a new phylogenetic analysis including all genera of Caprinae. Unexpectedly, Pseudonovibos is found to be robustly associated with Rupicapra, and closer to the Alpine than to the Pyrenean chamois. Several clues led us to interpret this result as a carry-over DNA contamination of Pseudonovibos by Rupicapra.
新描述的越南牛科动物“灵阳牛”（旋角牛属），基于从角碎片中提取的线粒体细胞色素b基因测序，已显示与羊亚科有关。为整合最大可用生物多样性，我们进行了一项新的系统发育分析，纳入了羊亚科的所有属。出乎意料的是，发现旋角牛属与岩羚羊属有很强的关联，且与高山瞪羚的关系比与比利牛斯岩羚羊更近。几条线索使我们将这一结果解释为旋角牛属被岩羚羊属的DNA污染残留。
