Abstract. Thripidae, one of the largest families of Thysanoptera, is widely distributed throughout the world. To explore the phylogenetic relationships and current classification of Thripidae, a cladistic analysis is presented based on 117 morphological characters scored from 114 species representing 94 genera. This analysis was used to reconstruct the ancestral feeding habits of Thripidae, with the result that leaf-feeding is recognised as ancestral within this family, and flower-feeding derived. Thripidae is recovered as a monophyletic group, but the three subfamilies Dendrothripinae, Sericothripinae and Panchaetothripinae are all recovered as nested within the fourth and major subfamily Thripinae. Sericothripinae is related to the Scirtothrips genus-group in Thripinae, but a close relationship to Echinothrips is not supported. Intergeneric relationships within Dendrothripinae are relatively well resolved. Three tribes in Panchaetothripinae are not monophyletic but Tryphactothripini genera form a clade with Panchaetothrips. Subfamily Thripinae is paraphyletic, but includes several monophyletic genus-groups (Rhamphothrips genus-group, Trichromothrips genus-group, Thrips genus-group, Frankliniella genus-group, Chirothrips genus-group). Relationships within the Thrips genus-group are poorly resolved, presumably due to a high degree of homoplasy. Five genera (Amomothrips, Moundinothrips, Smilothrips, Ctenothrips and Sciothrips) are placed into the Taeniothrips genus-group, and three genera (Salpingothrips, Tusothrips and Chaetanaphothrips) are proposed as the Chaetanaphothrips genus-group. The previously accepted Anaphothrips genus-group and Mycterothrips genus-group are not recovered, presumably because the supporting characters are merely superficial resemblance with no phylogenetic significance. This work resolves the systematic relationships among most thripid genera, as well as providing a morphological background for the evolution of Thripidae.

蓟马科（缨翅目：Terebrantia）的形态系统发育

摘要。蓟马科是缨翅目最大的科之一，广泛分布于世界各地。为了探索蓟马科的系统发育关系和当前分类，根据代表 94 属的 114 个物种的 117 个形态特征进行了分支分析。该分析用于重建蓟马的祖先摄食习性，结果食叶被认为是该科的祖先，而食花衍生。蓟马科作为一个单系群被恢复，但是三个亚科 Dendrothripinae、丝虫亚科和 Panchaetothripinae 都被恢复为嵌套在第四个和主要亚科 Thripinae 中。Sericothripinae 与 Thripinae 中的 Scirtothrips 属群相关，但不支持与 Echinothrips 的密切关系。Dendrothripinae 内的属间关系相对较好地解决。Panchaetothripinae 中的三个部落不是单系的，但 Tryphactothripini 属与 Panchaetothrips 形成一个进化枝。蓟马亚科是并系的，但包括几个单系属群（Rhamphothrips 属群、Trichromothrips 属群、蓟马属群、Frankliniella 属群、Chirothrips 属群）。蓟马属群内的关系很难解决，大概是由于高度的同质性。五个属（Amomothrips、Moundinothrips、Smilothrips、Ctenothrips 和 Sciothrips）被归入绦虫属群，三个属（Salpingothrips、Tusothrips 和 Chaetanaphothrips）被提议作为 Chaetanaphthrips 属群。之前接受的 Anaphothrips 属群和 Mycterothrips 属群没有恢复，大概是因为支持性状只是表面相似，没有系统发育意义。这项工作解决了大多数蓟马属之间的系统关系，并为蓟马科的进化提供了形态学背景。
