步甲是步甲科（Carabidae）步甲亚科（Carabinae）步甲亚族（Carabina）的一个大分支，被认为是由17个属组成的离散形态组。通过分析线粒体NADH脱氢酶亚基5（ND5）基因序列，研究了跗线甲的系统发育关系和进化模式。系统发育树表明，跗线动物的成员不形成一个单一的集群，即，不是单系的，至少有16个血统属于所谓的Carbatarsi出现在大约同一时间的Carabina辐射与其他部门的成员一起。这表明，这些谱系（图2a中的A、B、C、H、L、N、O、P、Q、R、S、T、U、V、W和X）可以被视为与其他谱系等同的遗传学上不同的谱系。自举值超过80%的组被认为是一个单一的谱系（分裂），只有两个例外，V和X。每个谱系的独立性已被传统的形态学假设，以及通过独立的方法构建的树上的单个聚类，通过替换外群而保持不变的拓扑结构等。一般来说，单个谱系中的成员在地理上是相连的。许多系统发育谱系由单一或少数物种组成，没有明显的形态分化。相反，这样一个“沉默的形态进化”，一个显着的形态分化偶尔发生在几个谱系。
The Latitarsi is one large division of the subtribe Carabina (subfamily Carabinae, family Carabidae), and has been considered as a discrete morphological group consisting of 17 genera. The phylogenetic relationships and evolutionary pattern of the Latitarsi ground beetles have been investigated by analyzing mitochondrial NADH dehydrogenase subunit 5 (ND5) gene sequences. The phylogenetic tree suggests that the Latitarsi members do not form a single cluster, i.e., not monophyletic and at least 16 lineages belonging to the so-called Latitarsi emerged at about the same time of the Carabina radiation together with the members of other divisions. This suggests that these lineages (A, B, C, H, L, N, O, P, Q, R, S, T, U, V, W and X in Fig. 2a) may be treated each as a phylogenetically distinct division equivalent to other divisions. The group with bootstrap value of more than 80 percent has been considered as a single lineage (division) with two exceptions, V and X. The independency of each lineage has been assumed by the traditional morphology as well as a single clustering on the trees constructed by independent methods, unchanged topology by replacement of outgroups, etc. Generally speaking, the members in a single lineage are geographically linked. Many phylogenetic lineages are composed of a single or only a few species without conspicuous morphological differentiation. In contrast to such a "silent morphological evolution", a remarkable morphological differentiation occasionally took place in several lineages.
