During evolution of carabid ground belltes, occasional radiation explosions of various sizes took place, sometimes accompanied by parallel morphological evolution in phylogenetically remote as well as close lineages. Type-switching model was first described as a evolutional model in subgenus Ohomopterus. At present, the same phenomenon has been reported form many subgenela, such as Coptolabrus, Acoptolabrus, etc. Overall, carabid evolution seems to be generally discontinuous.In 2003, we have collected many samples of two genera, Coptolabrus and Acoptolabrus, from Primorsky, Russia. The phylogeny of those samples have been examined by sequense comparison of the mitochondrial ND5 gene. And the phylogenetic properties of the subgenus Ohomopterus have been also examined by sequense comparison of the ND5 gene and the nuclear ITS I.The population represented by subsp. Kiiensis should be regarded as an authentic species and the nominotypical iwawakianus and two other subspecies are considered to be offspring of the hybrid between kiiensis and O.maiyasanus. O.uenoi is a descendant from a hybrid between the female of O.arrowianus and the male of either O.iwawakianus or O.kiiensis.

在步甲陆龟的进化过程中，偶尔会发生各种大小的辐射爆炸，有时伴随着系统发育上遥远和密切的谱系的平行形态进化。类型转换模型首先被描述为同翅亚属的进化模型。目前，许多亚属也报道了同样的现象，如Coptolabrus、Acoptolabrus等。总体而言，步甲的进化似乎总体上是不连续的。2003年，我们从俄罗斯滨海边疆区采集了Coptolabrus和Acoptolabrus两个属的许多样本。通过线粒体 ND5 基因的序列比较检查了这些样本的系统发育。并通过ND5基因和核ITS I的序列比对研究了同翅亚属的系统发育特性。 Kiiensis 应被视为真实物种，而典型 iwawakianus 和其他两个亚种被认为是 kiiensis 和 O.maiyasanus 杂交的后代。 O.uenoi 是雌性 O.arrowianus 与雄性 O.iwawakianus 或 O.kiiensis 杂交的后代。
