叶甲科（叶甲虫）的高级分类目前已识别出12或13个成熟的亚科，但它们之间的系统发育关系仍然不明确。完整的线粒体基因组是新产生的27个分类群，并结合现有的GenBank数据，提供一个数据集的108个线粒体基因组，涵盖所有亚科。最大似然法和贝叶斯推断下的系统发育分析恢复了所有亚科的单系性，除了Timarcha在一些分析中被分离出来。三个以前公认的主要分支的科被广泛支持：'chrysomeline'的分支组成（亚科（Galerucinae + Alticinae））;'sagrine'的分支与内部关系（（Bruchinae + Sagrinae）+（Criocerinae + Donacinae）），和'eumolpine'的分支组成（Spilopyrinae（Cassidinae（Eumolpinae（Cryptocephalinae + Lamprosomatinae）。这些分支之间的关系不同的数据处理和系统发育算法，并复杂的两个额外的深谱系，Timarcha和Synetinae。各种拓扑测试有利于PhyloBayes软件作为首选的推理方法，导致在（chrysomeline（eumolpines + sagrines））的安排，与Timarcha放置为姐妹的chrysomeline分支和Synetinae作为一个深谱系分裂附近的基地。而有丝分裂基因组提供了一个坚实的框架，为Eschomelidae的胚胎发育，基本的关系不同意现有的分子研究的拓扑结构，仍然是Eschomelidae胚胎遗传学的最困难的问题之一。
The high-level classification of Chrysomelidae (leaf beetles) currently recognizes 12 or 13 well-established subfamilies, but the phylogenetic relationships among them remain ambiguous. Full mitochondrial genomes were newly generated for 27 taxa and combined with existing GenBank data to provide a dataset of 108 mitochondrial genomes covering all subfamilies. Phylogenetic analysis under maximum likelihood and Bayesian inference recovered the monophyly of all subfamilies, except that Timarcha was split from Chrysomelinae in some analyses. Three previously recognized major clades of Chrysomelidae were broadly supported: the 'chrysomeline' clade consisting of (Chrysomelinae (Galerucinae + Alticinae)); the 'sagrine' clade with internal relationships of ((Bruchinae + Sagrinae) + (Criocerinae + Donaciinae)), and the 'eumolpine' clade comprising (Spilopyrinae (Cassidinae (Eumolpinae (Cryptocephalinae + Lamprosomatinae)))). Relationships among these clades differed between data treatments and phylogenetic algorithms, and were complicated by two additional deep lineages, Timarcha and Synetinae. Various topological tests favoured the PhyloBayes software as the preferred inference method, resulting in the arrangement of (chrysomelines (eumolpines + sagrines)), with Timarcha placed as sister to the chrysomeline clade and Synetinae as a deep lineage splitting near the base. Whereas mitogenomes provide a solid framework for the phylogeny of Chrysomelidae, the basal relationships do not agree with the topology of existing molecular studies and remain one of the most difficult problems of Chrysomelidae phylogenetics.
