    <abstract language="eng">The condition of certain neglected structures and their possible importance to the classification of the family Tabanidae are studied. The front coxae are considered as belonging to two types: 1) short and robust; 2) long and slender. The posterior edge of the meso-katepimeron presents two conditions: 1) without projection, 2) with backward projection. Similar conditions are found in the meso-Katepisternum, but with intermediate conditions. These characters are discussed in relation to the system proposed for the family by Mackerras. Conditions 1 and 2 of the former two structures separate, respectively, the Pangoniinae and Scepsidinae from the Chrysopsinae and Tabaninae. Condition 2 of the third structure seems to be developing independently in different groups of Tabaninae, with varying degrees of development

    The Brachylaimidae of Australian native animals are revised. Brachylaima dasyuri (Johnston, 1913) is redescribed from Dasyurus viverrinus, Phascogale tapoatafa and Isoodon macrourus. B. simile (Johnston, 1913) is removed from synonymy with B. dasyuri, reinstated as a valid species and redescribed from Perameles nasuta, Isoodon obesulus and Antechinus stuartii. B. antechini Peisley & Howell, 1975 is reduced to synonymy with B. simile. B. brindabellensis n. sp. is described from Rattus fuscipes. B. walterae n. sp. is described from Antechinus swainsonii and A. stuartii. B. delecta n. sp. is described from Antechinus flavipes. B. sandarsae n. sp. is described from Antechinus godmani. B. pulchellum (Johnston, 1917) is redescribed from Leucosarcia melanoleuca. An unnamed Brachylaima species is described from Isoodon macrourus. New host records are Brachylaima dasyuri from Phascogale tapoatafa and B. simile from Perameles nasuta. Dasyurotrema mascomai n. g., n. sp. is described from Antechinus swainsonii. The new genus is placed in the Panopistinae. It differs from the existing genera by having a single loop of the uterus passing anterior to the ventral sucker and the genital pore posterior to the posterior testis but still distinctly ventral. A second species of Dasyurotrema is recorded, but not described, from Antechinus stuartii. Brachylaimid metacercariae are described from Rhytida capillacea, Helicarion virens, H. mastersi and Vercularion strangei. In no case was a host species found to harbour more than one species from any brachylaimid genus at a single geographical site
