我们利用无翼(Wg)和磷酸烯醇式丙酮酸羧酸激酶(PEPCK)这两个核DNA基因座的序列数据重建了全北极步甲亚族Carabina(=Carabus s.l；鞘翅目，步甲科，步甲亚族，Carabini族)的系统发育。尽管Wg和PEPCK有部分相互冲突的系统发育信号，但对合并数据的分析得到了一棵解析良好的树。树状拓扑结构不支持先前提出的一些主要分类单元的相互单系性，而先前提出的其他8个亚科中除1个以外的所有分支都被恢复为单系支系；例外情况是副系。当季节生活史和幼虫食性这两个关键的生活史特征被映射到组合树上时，春季繁殖(没有幼虫越冬)和食虫性是祖先的特征。食软体动物显然至少进化了两次：一次是在一个小的基群(10种)中，另一次是在一个大的派生群(约340种)中，这一大群占卡拉比纳物种的42%。第三类幼虫，蚯蚓食虫，出现在两个相关的派生分支中，表现出中等的物种多样性(12%)。从没有幼虫越冬的祖先春繁殖型到幼虫越冬的秋季繁育型，幼虫越冬的秋季繁殖型在食虫和食软性物种中明显重复进化，但在蚯蚓饲养者中不重复进化。因此，Carabina现存的多样性依赖于最衍生的食软性物种群体中的高分化率。《伦敦林尼安学会》，《林尼安学会生物杂志》，2004年，第81期，135-149页。
We reconstructed the phylogeny of the holarctic carabid subtribe Carabina (= Carabus s.l.; Coleoptera, family Carabidae, supertribe Carabitae, tribe Carabini) using sequence data from two nuclear DNA loci: wingless (Wg) and phosphoenolpyruvate carboxykinase (PepCK). The analysis of the combined data resulted in a well-resolved tree, although Wg and PepCK had partially conflicting phylogenetic signals. The tree topology did not support the reciprocal monophyly of some previously proposed major divisions, whereas all but one of eight other previously proposed subdivisions were recovered as monophyletic clades; the exception was paraphyletic. When two key life-history traits, seasonal life cycle and larval diet, were mapped onto the combined tree, spring breeding (with no larval overwintering) and insectivorous were ancestral traits. Malacophagy has apparently evolved at least twice: once in a small basal group (ten species) and again in a large derived group (c. 340 species) that accounts for 42% of the species of Carabina. A third type of larva, earthworm feeders, appeared in two related, derived clades and represented moderate species diversity (12%). From the ancestral spring-breeder type with no larval overwintering, autumn-breeder types with larval overwintering apparently evolved repeatedly in insectivorous and malacophagous species, but not in earthworm feeders. Therefore, the extant diversity of the Carabina depends on the high rate of differentiation in the most derived group of malacophagous species. © 2004 The Linnean Society of London, Biological Journal of the Linnean Society, 2004, 81, 135‐149.
