The ovipositor morphology of Trichophora (Hemiptera: Heteroptera) is revisited. Skeletomuscular structure of the ovipositor of selected species and outgroups is documented. Homologies of the structures are established, different homology hypotheses of previous authors are discussed and rejected. The groundplan of the trichophoran ovipositor is reconstructed, apomorphic conditions of each part of the ovipositor are documented. A standard nomenclature is proposed for muscles associated with the ovipositor and extrinsic muscles of the female inner ectodermal genital tracts. Character transformations of the ovipositor are reconstructed via cladistic analysis. The concepts of "lanceolate ovipositor" and "plate-like ovipositor", frequently used in the literature, are discussed; it is concluded that no unambiguous definition of them is possible on a morphological basis, these terms refer merely to evolutionary grades rather than strictly distinct character states. "Plate-like ovipositors" evolved at least four times within Trichophora; they exhibit considerable differences among and within these clades. It is demonstrated that the "M- or W-shaped sclerites" of Pyrrhocoridae and Urostylididae are not homologous: in Pyrrhocoridae they are expansions of the mesal face of the posterior portion of valvifers IX, whilst the superficially similar structures in Urostylididae are infoldings of the ventral rim of the mesal portion of laterotergites IX.

从披针形到板状：Trichophoran产卵器的总体形态，术语和演变趋势。

再次探讨了滴虫（半翅目：异翅目）的产卵器形态。记录了选定物种和外群产卵者的骨骼肌结构。建立了结构的同源性，讨论并拒绝了先前作者的不同同源性假设。重建了三基色虫产卵器的平面图，并记录了产卵器各部分的无定形条件。对于与女性外胚层生殖道的产卵器和外在肌肉相关的肌肉，建议使用标准命名法。通过分类分析重构了产卵器的性状转变。讨论了文献中经常使用的“披针形产卵器”和“板状产卵器”的概念。结论是，在形态学上不可能对它们进行明确的定义，这些术语仅指进化等级而不是严格不同的性状。Trichophora中至少有四次“板状产卵器”进化。它们在这些分支之间和内部表现出相当大的差异。事实证明，Pyrrhocoridae和Urostylididae的“ M形或W形巩膜”不是同源的：在Pyrrhocoridae中，它们是valvifers IX后部的内膜面的扩展，而Urostylididae的表面相似结构是其内折叠。腹侧IX的内膜部分的腹缘。
