拟寄生蜂科是一个庞大的、生物多样性的寄生蜂科，传统上分为四个亚科；弹力蜂科是一个统一的（单属）和形态上不同的黄蜂家族，被认为与细蜂科有关。测定了5科87种高脂虫、3种弹性虫和16种外群种28S rDNA基因D2区（约560bp）的序列。构建了进化图，并与形态学研究的结论进行了比较。该基因在亚家族和部落水平上信息量最大。乌洛菲亚科和tetrastichin亚科的单系性得到了支持；Entedoninae和Euderinae的情况就不太清楚了。研究结果表明，绿蛛亚科是绿蛛科的派生类群，而非原认为的祖先类群，而绿蛛科的唯一属蓝蛛亚科属于绿蛛亚科。Eulophinae的部落被重新评估，只有三个被接受：Eulophini（包括Euplectrini和Elachertini）， Elasmini和Cirrospilini LaSalle部落。布塞克的奥菲里米尼，奥菲里米斯和奥菲里米斯除外。澳大利亚的三个小部落，Anselmellini， Ophelimini和Platytetracampini，分别从Eulophinae和Entedoninae中分离出来，但它们的确切关系和亚科地位尚未确定。另一个部落，Keryini，已知来自一个单一的澳大利亚属，被排除在Eulophinae和Eulophidae之外。
Eulophidae is a large and biologically varied family of parasitoid wasps, traditionally split into four subfamilies; Elasmidae is a uniform (single genus) and morphologically distinct family of wasps that are thought to be related to Eulophidae. The D2 region of the 28S rDNA gene (approximate to 560bp) of eighty-seven species of eulophid, three species of elasmid and sixteen outgroup species in five families was sequenced. Cladograms were constructed, and the results compared with conclusions drawn from morphological studies. The gene was most informative at the level of subfamily and tribe. The monophyly of both Eulophinae and Tetrastichinae is supported; that of Entedoninae and Euderinae is less clear. Results indicate that Eulophinae is a derived group within Eulophidae, rather than an ancestral group as previously thought, and that Elasmus, the sole genus of Elasmidae, belongs within this subfamily. The tribes of Eulophinae are reassessed and only three accepted: Eulophini (including Euplectrini and Elachertini), Elasmini and Cirrospilini LaSalle trib.n. for Boucek's Ophelimini with Ophelimus and Australsecodes excluded. Three small Australian tribes, Anselmellini, Ophelimini and Platytetracampini, are removed from Eulophinae and Entedoninae, respectively, but their exact relationships and subfamily status cannot as yet be decided. Another tribe, Keryini, known from a single Australian genus, is excluded from both Eulophinae and Eulophidae.
