Currently 26 sponge species are known for the Peruvian coast, but so far no raspailiids had been recorded from this region. Raspailiidae are distributed worldwide and its species are characterized by encrusting, massive, lobate, fan-shaped or branching growth forms, usually with a very hispid surface. In the present study, three new species of Raspailiidae are described from the Peruvian coast. Two new Eurypon spp. were collected at Islas Lobos de Afuera (Lambayeque). Eurypon lacertus sp. nov. is a thinly encrusting orange sponge with choanosomal skeleton composed of large tylostyles and small acanthostyles, and ectosomal skeleton with anisoxeas. Eurypon hookeri sp. nov. is a crustose, ruby red sponge, with choanosomal skeleton composed of large (subtylo)styles and acanthostyles, and ectosomal skeleton pierced by acanthostyles and (subtylo)styles, often surrounded by bouquets of smaller styles. The third new species, Plocamione matarani sp. nov., was collected at Matarani (Arequipa). It is a thinly encrusting orange sponge, the only Plocamione with two categories of choanosomal styles, and a single category of ectosomal styles, acanthostyles and anisoacanthostrongyles. These are the first records of Eurypon and Plocamione for the Peruvian coast, and the entire Southeastern Pacific, in the case of the latter.
目前已知秘鲁海岸有26种海绵物种，但到目前为止，该地区尚未记录到瑞氏海绵科物种。瑞氏海绵科分布于全球，其物种的特征是具有覆盖状、块状、叶状、扇形或分支状的生长形态，表面通常多刺。在本研究中，描述了来自秘鲁海岸的3种瑞氏海绵科新物种。在阿富埃拉岛（兰巴耶克）采集到了2种新的真瘤海绵属物种。新物种蜥蜴真瘤海绵是一种薄覆盖状橙色海绵，其体腔骨骼由大型 tylostyles 和小型针状骨针组成，皮层骨骼有不等骨针。新物种胡氏真瘤海绵是一种壳状红宝石红色海绵，其体腔骨骼由大型（亚 tylostyles）骨针和针状骨针组成，皮层骨骼被针状骨针和（亚 tylostyles）骨针穿透，常被一束束较小的骨针围绕。第三个新物种，马塔拉尼褶海绵，是在马塔拉尼（阿雷基帕）采集到的。它是一种薄覆盖状橙色海绵，是唯一一种具有两类体腔骨针和一类皮层骨针（针状骨针和不等针状强骨针）的褶海绵。这些是秘鲁海岸首次记录到的真瘤海绵属和褶海绵属物种，就后者而言，也是整个东南太平洋的首次记录。
