Trager（1991）的双索蚁种群的火蚁根据工蚁幼虫以及工蚁、雄蚁和雌蚁（蜂王种姓中有翼或无翅的成员）的成虫形态进行了修订。在成年男性和女性发生的种内变异量相当于工人，使这些种姓获得的分类信息没有比工人的信息更好。本文报道一新种，S. metallica，描述了从巴西南部，基于成年工人，成年雌，男性，和工人幼虫。以下分类的变化是：S。将S.种组; S. tridens和S.取代基位于S.三叉戟种群; S. metallica新种，S. daguerrei，S. electra，S. Albertlis，S. interrupta、S. invicta、黑翅叶蝉S. macdonaghi，S. megergates，S. pusillignis、细叶藓S. pythia，S. quinquecuspis、五爪草S. richteri，S. saevissima和S. weyrauchi位于S. saevissima种组;和S. geminata、双孢草S. xyloni，S. amblychila，S. aurea，S. gayi和S. bruesi留在S. geminata种组旧的分类，指定复合体和亚复合体，被放弃。对于鼠伤寒沙门saevissima物种组，男性和女性的成年人，以及工人幼虫，描述和诊断每个物种。诊断和检索表（二分法和表格）提供的成年工人，最常见的收集材料，和物种的分布进行了总结。
The fire ants of the Solenopsis geminata species-group of Trager (1991) are revised based on the morphology of worker larvae and of adult forms of workers, males, and gynes (winged or dealated members of the queen caste). The amount of intraspecific variation occurring in the adult males and gynes was equivalent to that of workers, making the taxonomic information gained from these castes no better than information from the workers. A new species, S. metallica, is described from southern Brazil, based on adult workers, adult gynes, males, and worker larvae. The following classification changes are made: S. virulens is placed in the S. virulens species-group; S. tridens and S. substituta are placed in the S. tridens species-group; S. metallica new species, S. daguerrei, S. electra, S. hostilis, S. interrupta, S. invicta, S. macdonaghi, S. megergates, S. pusillignis, S. pythia, S. quinquecuspis, S. richteri, S. saevissima, and S. weyrauchi are placed in the S. saevissima species-group; and S. geminata, S. xyloni, S. amblychila, S. aurea, S. gayi, and S. bruesi are left in the S. geminata species-group. The older classification, which designated complexes and subcomplexes, is abandoned. For the S. saevissima species-group, adults of males and gynes, as well as worker larvae, are described and diagnosed for each species. Diagnoses and keys (dichotomous and tabular) are provided for adult workers, the most commonly collected material, and distributions of the species are summarized.
