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.
利用从智利各地采集的66个智利Ceroglossus步甲标本的线粒体ND5基因序列构建了系统发育树。这些树表明，所检测的Ceroglossus标本由四个在2500万至3000万年前分化的系统发育谱系组成。结果与吉鲁（1996年）基于形态学提出的分类一致，其中Ceroglossus被分为四个物种组。尽管这些步甲显示出显著的颜色多态性，但颜色模式与地理相关，并非物种特异性，这表明一些生态或环境因素参与了其决定过程。
