Two new species of the genus Styela are described, with very rare characteristics in this genus: both are shallow-water and tropical, with more than two gonads in each side of the body. Styela panamensis sp. nov. is described from specimens collected in Bocas del Toro, Atlantic coast of Panama, and Styela multicarpa sp. nov. from specimens collected in Espírito Santo, Brazil and Margarita Island, Venezuela. They are probably native to the south Caribbean and S. multicarpa sp. nov. is introduced in Brazil.
描述了柄海鞘属的两个新物种，它们在该属中具有非常罕见的特征：均为浅水热带物种，身体两侧各有两个以上的性腺。巴拿马柄海鞘新种（Styela panamensis sp. nov.）是根据在巴拿马大西洋海岸的博卡斯德尔托罗采集的标本描述的，多果柄海鞘新种（Styela multicarpa sp. nov.）是根据在巴西圣埃斯皮里图和委内瑞拉玛格丽塔岛采集的标本描述的。它们可能原产于加勒比海南部，多果柄海鞘新种已被引入巴西。
