Harpalinae is a large, monophyletic subfamily of carabid ground beetles containing more than 19,000 species in approximately 40 tribes. The higher level phylogenetic relationships within harpalines were investigated based on nucleotide data from two nuclear genes, wingless and 28S rDNA. Phylogenetic analyses of combined data indicate that many harpaline tribes are monophyletic, however the reconstructed trees showed little support for deeper nodes. In addition, our results suggest that the Lebiomorph Assemblage (tribes Lebiini, Cyclosomini, Graphipterini, Perigonini, Odacanthini, Lachnophorini, Pentagonicini, Catapiesini and Calophaenini), which is united by a morphological synapomorphy, is not monophyletic, and the tribe Lebiini is paraphyletic with respect to members of Cyclosomini. Two unexpected clades of tribes were supported: the Zuphiitae, comprised of Anthiini, Zuphiini, Helluonini, Dryptini, Galeritini, and Physocrotaphini; and a clade comprised of Orthogoniini, Pseudomorphini, and Graphipterini. The data presented in this study represent a dense sample of taxa to examine the molecular phylogeny of Harpalinae and provide a useful framework to examine the origin and evolution of morphological and ecological diversity in this group.
多齿龙次科是一个大型的、单系的步甲科亚科,包含超过 19000 种,分布于大约 40 个族中。本研究基于两个核基因(无翅基因和 28S rDNA)的核苷酸数据,探讨了多齿龙次科内部的高级系统发育关系。联合数据分析的系统发育分析表明,许多多齿龙次科是单系的,但重建的系统树对更深的节点几乎没有支持。此外,我们的结果表明,由形态学synapomorphy 联合的 Lebiomorph 组合(族 Lebiini、Cyclosomini、Graphipterini、Perigonini、Odacanthini、Lachnophorini、Pentagonicini、Catapiesini 和 Calophaenini)不是单系的,而 Lebiini 族相对于 Cyclosomini 族是并系的。支持了两个意想不到的族聚类:由 Anthiini、Zuphiini、Helluonini、Dryptini、Galeritini 和 Physocrotaphini 组成的 Zuphiitae;以及由 Orthogoniini、Pseudomorphini 和 Graphipterini 组成的一个聚类。本研究中提出的数据代表了一个密集的分类单元样本,用于检验多齿龙次科的分子系统发育,并为研究该类群形态和生态多样性的起源和进化提供了有用的框架。
