Meloid甲虫的形态和生物学特征都很好地描述了这一点。以往基于形态特征的系统发育假说假设复杂的生物学新事物重复平行进化。在这项工作中，几个类群的四个亚科和几乎所有的部落代表meloid多样性之间的关系进行了检查，使用线粒体（16S）和核（ITS 2）DNA序列，在25个属（以Anthicidae作为外群）。模拟了16S和ITS2 rRNA的二级结构。ITS2结构代表了家族和部落水平上的信息特征的突触形态条件。根据16S和ITS2 rDNA序列和形态生物学特征的单独和组合分析，系统发育假设进行了测试，并与以前的形态分类进行了比较。分子测年允许的主要步骤的Meloidae，在早白垩世期间演变，然后辐射相当大的通过hypermetaboly和寄生行为，并与重复，平行进化的幼虫phoresy在其主机的进化历史的轮廓。(c)2008年爱思唯尔公司All rights reserved.
Meloid beetles are well characterised by both morphological and biological features. Previous phylogenetic hypotheses based on morphological characters assumed the repeated parallel evolution of complex biological novelties. In this work relationships among several taxa of the four subfamilies and almost all tribes representing meloid diversity are examined by using mitochondrial (16S) and nuclear (ITS2) DNA sequences, in 25 genera (using Anthicidae as outgroup). Secondary structure of 16S and ITS2 rRNAs were modelled. ITS2 structure represents a synapomorphic condition for the family and informative characters at the tribal level. Phylogenetic hypotheses based on separate and combined analysis of the 16S and ITS2 rDNA sequences, and morpho-biological characters were tested, and compared with previous morphological classifications. Molecular dating allowed an outline of the main steps of the evolutionary history of Meloidae, which evolved during Early Cretaceous and then radiated considerably with the adoption of hypermetaboly and parasitic behaviour, and with repeated, parallel evolution of larval phoresy on its hosts.
