Therevidae (stilleto flies) are a little-known family of asiloid brachyceran Diptera (Insecta). Separate and combined phylogenetic analyses of 1200 bases of the 28S ribosomal DNA and 1100 bases of elongation factor-1alpha were used to infer phylogenetic relationships within the family. The position of the enigmatic taxon Apsilocephala Kröber is evaluated in light of the molecular evidence. In all analyses, molecular data strongly support the monophyly of Therevidae, excluding Apsilocephala, and the division of Therevidae into two main clades corresponding to a previous classification of the family into the subfamilies Phycinae and Therevinae. Despite strong support for some relationships within these groups, relationships at the base of the two main clades are weakly supported. Short branch lengths for Australasian clades at the base of the Therevinae may represent a rapid radiation of therevids in Australia.
剑蝇科（刺蝇）是双翅目（昆虫纲）突眼蝇类中一个鲜为人知的科。对28S核糖体DNA的1200个碱基和延伸因子-1α的1100个碱基进行单独和联合的系统发育分析，以推断该科内的系统发育关系。根据分子证据对神秘分类单元克氏无角蝇的位置进行了评估。在所有分析中，分子数据有力地支持了剑蝇科（不包括无角蝇）的单系性，以及剑蝇科分为两个主要分支，这与该科先前分为藻蝇亚科和剑蝇亚科的分类相对应。尽管对这些类群中的一些关系有有力支持，但两个主要分支基部的关系支持较弱。剑蝇亚科基部的澳大拉西亚类群的短分支长度可能代表了剑蝇在澳大利亚的快速辐射。
