We describe three new species of Eumida from shallow estuarine and shelf bottoms from south and southeastern Brazil as part of a regional survey of the family Phyllodocidae. Previous regional records of Eumida sanguinea (Örsted, 1843) are herein referred to Eumida dracodermica sp. nov. The two species differ in the size of the prostomium, the distribution of micropapillae on the proboscis, and the shape of the dorsal cirri. Eumida macrophthalma sp. nov. has much larger eyes than the other two species described herein. The dorsal cirri on anterior median segments are rounded and on median and posterior segments they are asymmetrical and cordiform, longer than the dorsal cirri in Eumida dracodermica sp. nov. The lanceolate median dorsal cirri in Eumida delicata sp. nov. are only shared with E. ockelmanni Eibye-Jacobsen, 1987. It is also possible to diagnose the three species by their dorsal whitish pigmentation patterns on the first segments of living or well conserved animals.
作为叶须虫科区域调查的一部分,我们描述了来自巴西南部和东南部浅海河口和陆架底部的三种新的真须虫属物种。此前关于血红真须虫(厄斯泰德,1843年)的区域记录在此被归为新物种龙皮真须虫。这两个物种在前叶大小、吻上微乳头的分布以及背触须的形状上存在差异。新物种大眼真须虫的眼睛比本文描述的其他两个物种大得多。前中节上的背触须呈圆形,中节和后节上的背触须不对称且呈心形,比龙皮真须虫的背触须长。新物种精致真须虫的披针形中背触须仅与1987年的奥克曼真须虫共有。还可以通过活体或保存良好的动物第一节上的白色背色素沉着模式来鉴别这三个物种。
