在澳大利亚，描述了属于黄锥虫亚科、锥虫亚科的8个毡虫科种和代表毡虫亚科和毡虫亚科的3个新属的雌性异配型。其他亚科的成员是雄性异型交配的。讨论了其他双翅目家庭中女性异型通婚的发生及其意义。有证据表明，在具有Y/X或Y/XA型性别决定机制（Y染色体雄性决定，X染色体和常染色体雌性决定）的物种中，由于性染色体中缺乏差异区域和复杂的剂量补偿机制，雌性异型配子通过小的效价变化进化而来。这种转变不太可能发生在具有X/ a或果蝇性别决定系统（X染色体雌性决定，常染色体雄性决定）的物种中。
Female heterogamety is described in eight Australian species of Tephritidae belonging to Chrysotrypanea, Tephritis, and three new genera representing the subfamilies Tephritinae and Oedaspinae. Members of other subfamilies are male heterogametic. The occurrence and significance of female heterogamety in other Dipteran families are discussed. Evidence suggests that female heterogamety evolved through small potency changes in a species with either a Y/X or Y/XA type sex determining mechanism (Y- chromosome male determining; X-chromosome and autosomes female determining) which lacked differential regions in the sex chromosomes and elaborate mechanisms for dosage compensation. It is unlikely that the shift could have occurred in a species with an X/A or Drosophila system of sex determination (X-chromosome female determining; autosomes male determining).
