A literature compilation was done to gather information about Cecidomyiidae galls on Clusiaceae in Brazil. Botanical names were verified in the site "Flora do Brasil" as well as data on plant distribution and origin. Two herbaria were visited in order to examine galled specimens of Clusiaceae and retrieve new locality records. Thirteen gall morphotypes have been recorded on three genera (Clusia, Garcinia, and Tovomita) and eight species. Clusia showed the greatest number of galled species. Tovomita brevistaminea is the super host species. Only three gallers, Parazalepidota clusiae, Clusiamyia granulosa and C. nitida, were identified at species level, which highlights how the taxonomy of the gall midges is still poorly known. The examination of galled exsiccates resulted in the expansion of their distribution area. The low gall richness as well as the low number of galled plants on Clusiaceae can be related to the presence of resinous sticky sap and waxy cuticle. The known occurrence of gallers associated with Clusiaceae is restricted to the Atlantic Forest as their host plants. The gallers distribution is less wide than that of the host plants, indicating that their geographic limits can be further extended.
为收集巴西藤黄科植物上瘿蚊瘿的相关信息进行了文献汇编。植物名称在“巴西植物志”网站上得到核实，同时还核实了植物分布和起源的数据。访问了两个植物标本馆，以便检查藤黄科的瘿标本并获取新的产地记录。已在三个属（藤黄属、藤黄属和托沃米塔属）和八个物种上记录了13种瘿形态类型。藤黄属的瘿化物种数量最多。短蕊托沃米塔是超级寄主物种。仅在物种层面鉴定出三种瘿蚊，即藤黄副扎勒皮多塔瘿蚊、颗粒藤黄瘿蚊和闪亮藤黄瘿蚊，这凸显了瘿蚊分类学仍鲜为人知的情况。对带瘿标本的检查导致其分布范围扩大。藤黄科植物上瘿丰富度低以及带瘿植物数量少可能与树脂状粘性汁液和蜡质表皮的存在有关。已知与藤黄科相关的瘿蚊的出现仅限于大西洋森林，因为它们的寄主植物就在那里。瘿蚊的分布范围比寄主植物的分布范围窄，这表明它们的地理界限可能会进一步扩大。
