A new species of Cladochaeta Coquillett (Diptera: Drosophilidae) is described, C. caxiuana sp. nov. from the Brazilian Amazon, based on 10 male and 10 female specimens obtained from nymphs of Sphodroscarta trivirgata (Amyot Serville, 1843) (Hemiptera: Auchenorrhyncha: Aphrophoridae). The female of Cladochaeta atlantica Pirani Amorim, 2016 is described based on specimens reared from spider egg sacs of the spider Cryptachaea migrans (Keyserling, 1884) (Araneae: Theridiidae) obtained in the state of Espírito Santo, Brazil. This is the first record of this fly genus attacking a spider egg sac. The species Cladochaeta sororia (Williston, 1896) is recorded for the first time from Brazil, based on specimens collected in an urban garden in the Amazon. In addition, an unidentified female specimen of Cladochaeta Coquillett, 1900 was obtained from the cocoon of a spider wasp of the genus Notocyphus Smith (Hymenoptera: Pompilidae).
描述了一种新的克拉多毛蠓属（Cladochaeta Coquillett）（双翅目：果蝇科）物种，即来自巴西亚马逊地区的卡修阿纳克拉多毛蠓（Cladochaeta caxiuana sp. nov.），基于从三线斯氏叶蝉（Sphodroscarta trivirgata (Amyot & Serville, 1843)）（半翅目：头喙亚目：沫蝉科）若虫中采集到的10只雄性和10只雌性标本。基于从巴西圣埃斯皮里图州采集的迁徙隐腹蛛（Cryptachaea migrans (Keyserling, 1884)）（蜘蛛目：球蛛科）的蜘蛛卵囊中饲养出的标本，描述了2016年的大西洋克拉多毛蠓（Cladochaeta atlantica Pirani & Amorim）的雌性。这是该蝇类属攻击蜘蛛卵囊的首次记录。基于在亚马逊地区一个城市花园中采集的标本，巴西首次记录了索氏克拉多毛蠓（Cladochaeta sororia (Williston, 1896)）物种。此外，还从诺托西弗斯属（Notocyphus Smith）（膜翅目：蛛蜂科）的一种蜘蛛黄蜂的茧中获得了一只身份不明的1900年的克拉多毛蠓属雌性标本。
