Two Pantanal areas were investigated in Corumbá, Mato Grosso do Sul. The field works were carried out in five trails, in August and December/2011 and April/2012. Seventy-six gall morphotypes were found in 52 host plants, 22 of them were identified at species level and 30 at genus. Fabaceae, Myrtaceae and Sapindaceae were the plant families with the greatest richness of gall. Leaves were the plant organ with the greatest gall richness. Six gall shapes were found - globoid, lenticular, fusiform, cylindrical, conical, and marginal roll. The three first were the most common. Five colors were observed - green, brown, red, yellow, and black. Green and brown predominated. Most were glabrous and one-chambered. These features have been indicated in several Brazilian biomes. Diptera (Cecidomyiidae) were the most frequent gallers. The associated fauna comprised parasitoids (Eulophidae, Braconidae, Eupelmidae, Eurytomidae, Platygastridae, and Pteromalidae), inquilines (Cecidomyiidae: Trotteria Kieffer, 1902, Hymenoptera: Tanaostigmoides Ashmead, 1896, Hemiptera, Lepidoptera and Thysanoptera) and predators (Pseudoscorpionida: Olpiolum medium Beier, 1931, Cecidomyiidae: Lestodiplosini and Hymenoptera: Formicidae). Parasitoids were the most frequent. Multiparatism was observed. Our data represent the first contribution to the knowledge of the associated fauna in the Pantanal.
在南马托格罗索州的科伦巴对两个潘塔纳尔地区进行了调查。2011年8月、12月以及2012年4月，在五条样线上开展了野外工作。在52种寄主植物上发现了76种瘿形态类型，其中22种在物种水平上得到鉴定，30种在属水平上得到鉴定。豆科、桃金娘科和无患子科是瘿种类最为丰富的植物科。叶片是瘿种类最为丰富的植物器官。发现了六种瘿形状——球状、透镜状、纺锤形、圆柱形、圆锥形和边缘卷曲形。前三种最为常见。观察到五种颜色——绿色、棕色、红色、黄色和黑色。绿色和棕色占主导。大多数瘿无毛且为单室。这些特征在巴西的几个生物群落中都有体现。双翅目（瘿蚊科）是最常见的造瘿生物。相关动物群包括寄生蜂（姬小蜂科、茧蜂科、旋小蜂科、广肩小蜂科、扁股小蜂科和金小蜂科）、寄居生物（瘿蚊科：Trotteria Kieffer，1902，膜翅目：Tanaostigmoides Ashmead，1896，半翅目、鳞翅目和缨翅目）和捕食者（伪蝎目：Olpiolum medium Beier，1931，瘿蚊科：Lestodiplosini和膜翅目：蚁科）。寄生蜂最为常见。观察到了多寄生现象。我们的数据是对潘塔纳尔地区相关动物群知识的首次贡献。
