Three species of the genus Allocosa Banks, 1900 from southern South America are redescribed: Allocosa alticeps (Mello-Leitão, 1944), A. brasiliensis (Petrunkevitch, 1910) and A. senex (Mello-Leitão, 1945). The female of A. senex is described for the first time and the species is revalidated. A new species, A. marindia sp. nov. from southern Uruguay and southern Brazil is described. The new species is distinguished by the flattened terminal apophysis of the male bulb and the conspicuous pointed projections on the posterior margin of the female epigynum. The species inhabits in sandy estuarine and oceanic coasts with psammophile vegetation.
对来自南美洲南部的Allocosa Banks属的三个物种进行了重新描述：高头Allocosa（梅洛-莱唐，1944年）、巴西Allocosa（彼得伦凯维奇，1910年）和老年Allocosa（梅洛-莱唐，1945年）。首次描述了老年Allocosa的雌性，并对该物种进行了重新确认。描述了一个来自乌拉圭南部和巴西南部的新物种——马林迪亚Allocosa。该新物种的特征是雄性球茎的末端骨片扁平，雌性外雌器后缘有明显的尖突。该物种栖息于有嗜沙植物的沙质河口和海洋海岸。
