The mirid subfamily Orthotylinae is hyperdiverse in Australia but poorly described; this work is part of a series of papers on the documentation of this fauna. Two new species of the Australian endemic plant bug genus Myrtlemiris Cheng, Mututantri & Cassis (Heteroptera: Miridae: Orthotylinae: Orthotylini) are described as new to science: Myrtlemiris kararensis, sp. nov., and M. lochada, sp. nov. The new Australian genus and species Neomyrtlemiris picta gen. nov. et sp. nov. are also described. Myrtlemiris is analysed phylogenetically using 32 morphology-based characters, as well as molecular alignments (COI, 16S rRNA, 18S rRNA and 28S rRNA; including 1958 base pairs) with the genus found to be monophyletic based on molecular, morphological and combined analyses. Neomyrtlemiris is the sister to Myrtlemiris. Host plant association analysis demonstrated constraints to the myrtaceous tribe Chamelaucieae, with Malleostemon and Calytrix recovered as ancestral host plants. Ancestral state reconstructions were carried out on male genitalic structures, demonstrating the phylogenetic value of endosomal spicules. This work demonstrates that the Orthotylinae are a rich component of Australia’s biodiversity, particularly in the south-west of Western Australia.

桃金娘的综合分子和形态系统发育、内体针状体的进化、两个新物种和新桃金娘的描述，gen。十一月 (昆虫纲 : 异翅目 : Miridae : Orthotylinae)

mirid 亚科 Orthotylinae 在澳大利亚是高度多样化的，但描述得很少。这项工作是关于该动物群文献的系列论文的一部分。澳大利亚地方性植物虫属 Myrtlemiris Cheng、Mututanttri 和黑醋栗（异翅目： Miridae：Orthotylinae：Orthotylini）的两个新物种被描述为科学新物种：Myrtlemiris kararensis，sp。11 月，和 M. lochada，sp。十一月 澳大利亚新属和种 Neomyrtlemiris picta gen。十一月 等 sp. 十一月 也有说明。使用 32 个基于形态学的特征以及分子排列（COI、16S rRNA、18S rRNA 和 28S rRNA；包括 1958 个碱基对）对桃金娘进行系统发育分析，根据分子、形态和组合分析发现该属是单系的。新桃金娘是桃金娘的妹妹。寄主植物关联分析表明对桃金娘族 Chamelaucieae 的限制，其中 Malleostemon 和 Calytrix 作为祖先寄主植物被回收。对男性生殖器结构进行了祖先状态重建，证明了内体针状体的系统发育价值。这项工作表明，Orthotylinae 是澳大利亚生物多样性的重要组成部分，尤其是在西澳大利亚西南部。
