Thirteen new species and varieties of dictyostelid cellular slime molds (csm) were isolated from soils of the Atlantic Subtropical Rain Forest at the Iguazú Falls, Northeastern Misiones Province, Argentina. Seven new species are described herein, one of them is a Polysphondylium, while the rest of the species belong to the genus Dictyostelium. Also, six taxa are new varieties of Dictyostelium and Acytostelium, which will be reported later. Fourteen Northern Hemisphere (Tikal) species have also been isolated from Iguazú soils, some of them new records for Southern South America. This csm community, when compared with others from forests of the Northern Hemisphere, particularly Tikal, Guatemala, give some insight into a possibly different evolutionary history and/or natural selection in the two areas.
从阿根廷米西奥内斯省东北部伊瓜苏瀑布的大西洋亚热带雨林土壤中分离出13种新的网柄菌属细胞黏菌（csm）物种和变种。本文描述了7个新物种，其中1个是多管柄菌属，其余物种属于盘基网柄菌属。此外，有6个分类单元是盘基网柄菌属和无柄网柄菌属的新变种，将在以后报告。还从伊瓜苏土壤中分离出14种北半球（蒂卡尔）物种，其中一些是南美洲南部的新记录。与北半球森林（特别是危地马拉的蒂卡尔）的其他群落相比，这个csm群落为这两个地区可能不同的进化历史和/或自然选择提供了一些见解。
