利用从智利各地采集的66个智利金龟子标本的线粒体ND5基因序列，构建了系统发育树。这些树表明，所研究的Ceroglossus标本由四个系统发育谱系组成，它们之间存在25-30年的分歧。这一结果与Jiroux(1996)提出的基于形态的分类是一致的，该分类将Ceroglossus划分为4个种组。尽管这些地面甲虫揭示了显著的颜色多态，但这种颜色模式是地理上相关的，并不是物种特有的，这表明一些生态或环境因素参与了决定它的过程。
The phylogenetic trees have been constructed using the mitochondrial ND5 gene sequences for 66 specimens of the Chilean Ceroglossus ground beetles collected from various localities of Chile. The trees show that the Ceroglossus specimens examined are composed of four phylogenetic lineages that have diverged 25-30 MYA. The results are consistent with the classification proposed by Jiroux (1996) based on morphology, in which Ceroglossus is divided into four species groups. Despite a remarkable color polymorphism revealed by these ground beetles, the color pattern is geographically linked and is not species-specific, suggesting that some ecological or environmental factors are involved in determining it.
