Dexiini是澳大利亚寄蝇科动物群的重要组成部分，包括主要寄生于金龟子科或天牛科甲虫幼虫的物种。本文提供了一个属检索表和所有特有属的种检索表（不包括Senostoma的某些种组）。Senostoma被分成四个种组（长柄、红柄、斑点和毛状），每个种组被分别描述和处理。占主导地位的longipes组进行了修订（种键），其余的群体进行了彻底审查，确定了推定的物种概念。Prosena没有修订，但列出了所有有效的澳大拉西亚物种，评估了现有的物种检索表，并讨论了各种分类和命名困难。中国特有属（Prosena除外）由原来的13个订正为14个有效属，47个订正为85个种（包括2个未定名）。描述了六个新属：Patulifrons、Rasiliverpa（基于之前置于Billaea的两个物种）、Cantrellius、Gemursa、Paulipalpus和Effusimentum。五个属名是新合成的：Anatropomyia Malloch，1930和Hobartia Malloch，1930 = Trichostylum Macquart，1851; Acucera Malloch，1930 = Geraldia 1933 = Senostoma Macquart，1847。共有73种被描述或重新描述。其中包括13个属的43个新种（最值得注意的是Trichostylum（10），Geraldia（12）和Senostoma（7））。另有17个物种（每一个都基于不充分的材料）没有被描述，但通过列入物种检索表进行了诊断。其中6个种的新名称为：Chaetogaster diversa Paramonov，1954 = Trixa lateralis步行者，1849;奥拉erasmusi Paramonov，1968 = Rutilia nigrithorax Macquart，1851;黑毛毛革蜱，1930 = Dexia tessellata Macquart，1851;普通毛革蜱，1930 = Dexia testaceicornis Macquart，1851。建立了9个新组合：黄角毛柱藻（Trichostylum flavicorne，Malloch，1930）;特毛柱藻（Trichostylum peculiare，Malloch，1930）;稻纵卷叶螟（Rasiliverpa agrianomei，Mesnil，1969）;拟稻纵卷叶螟（Rasiliverpa vicinella，Mesnil，1969）;山老鹳草（Geraldia montana，Malloch，1851）;威氏芦条藻（Rutilotrixa wilsoni，Paramonov，1954）;长柄长喙毛口藻（Senostoma longipes，Macquart，1846）。对Bilaea agrianomei Mesnil，1969进行了选择型命名。对澳大拉西亚属的亲缘关系进行了综述。这些包括两个主要的谱系，辐射在不同的适应区，利用幼虫主机在不同的壁龛。因此，龙骨属寄生金龟子居住在土壤中，而非龙骨属攻击主要是木居Cerambyorae。
The Dexiini form a significant component of the Australasian tachinid fauna and include species that parasitise mainly larvae of scarabaeid or cerambycid beetles. A generic key and keys to species of all endemic genera (some species-groups of Senostoma excepted) are provided. senostoma is divided into four species-groups (longipes, rubricarinatum, punctipenne and hirsutilunula), each described and treated separately. The dominant longipes-group is revised (with a species key), and the remaining groups thoroughly reviewed, with putative species concepts identified. Prosena is not revised, but all valid Australasian species are listed, existing species keys assessed, and various taxonomic and nomenclatural difficulties discussed. The endemic genera (Prosena excepted) are revised from 47 to 85 species (2 nomina dubia included) in 14 valid genera (previously 13). Six new genera are described: Patulifrons, Rasiliverpa (based on two species previously placed in Billaea), Cantrellius, Gemursa, Paulipalpus and Effusimentum. Five generic names are newly synonymized: Anatropomyia Malloch, 1930 and Hobartia Malloch, 1930 = Trichostylum Macquart, 1851; Acucera Malloch, 1930 = Geraldia 1933 = Senostoma Macquart, 1847. In all, 73 species are described or redescribed. These comprise 43 new species described in 13 genera (most notably in Trichostylum (10), Geraldia (12) and Senostoma (7)). An additional 17 species (each based on inadequate material) are left undescribed, but are diagnosed by inclusion in species keys. Six species names are newly synonymized: Chaetogaster diversa Paramonov, 1954 = Trixa lateralis Walker, 1849; Ola erasmusi Paramonov, 1968 = Rutilia nigrithorax Macquart, 1851; Austrodexia communis Malloch, 1930 = Dexia appendiculata Macquart, 1851; Austrodexia mixta Malloch, 1930 = Dexia longipes Macquart, 1846; Lasiocalypter nigrihirta Malloch, 1930 = Dexia tessellata Macquart, 1851; Lasiocalyptrina modesta Malloch, 1930 = Dexia testaceicornis Macquart, 1851. Nine new combinations are established: Trichostylum flavicorne (Malloch, 1930); Trichostylum peculiare (Malloch, 1930); Rasiliverpa agrianomei (Mesnil, 1969), Rasiliverpa vicinella (Mesnil, 1969); Geraldia montana (Malloch, 1851); Rutilotrixa wilsoni (Paramonov, 1954); Senostoma longipes (Macquart, 1846). A lectotype is designated for Bilaea agrianomei Mesnil, 1969. The relationships of Australasian genera are reviewed. These comprise two main lineages, which have radiated in distinct adaptive zones, utilizing larval hosts in separate niches. Thus carinate genera parasitise Scarabaeidae resident in soil, while non-carinate genera attack mainly wood-dwelling Cerambycidae.
