The Order Suberitida is defined as a group of marine sponges without an obvious cortex, a skeleton devoid of microscleres, and with a deletion of a small loop of 15 base pairs in the secondary structure of the 28S rDNA as a molecular synapomorphy. Suberitida comprises three families and 26 genera distributed worldwide, but mostly in temperate and polar waters. Twenty species were reported along the entire Brazilian coast, and although the north-eastern coast of Brazil seems to harbour a rich sponge fauna, our current knowledge is concentrated along the south-eastern Atlantic coast. A survey was implemented along the northern coast of Brazil, and the collection allowed the identification of six species belonging to the Order Suberitida. Two of them are considered new to science: Suberites purpura sp. nov., Hymeniacidon upaonassu sp. nov., and four, Halichondria (Halichondria) marianae Santos, Nascimento & Pinheiro, 2018, Halichondria (H.) melanadocia de Laubenfels, 1936, Suberites aurantiacus (Duchassaing & Michelotti, 1864), and Terpios fugax Duchassaing & Michelotti, 1864, are re-described. Taxonomic comparisons are made for Tropical Western Atlantic species and type species of the four genera. Finally, an identification key for the Western Atlantic Suberites species is provided.

巴西未开发的东北海岸六种 Suberitida (Porifera: Demospongiae) 的形态描述，重点是两个新物种

Suberitida 目被定义为一组海绵，没有明显的皮质，没有微孔的骨架，并且在 28S rDNA 的二级结构中缺失了一个 15 个碱基对的小环作为分子突触。Suberitida 包括三个科和 26 属，分布于世界各地，但主要分布在温带和极地水域。据报道，整个巴西海岸有 20 种，尽管巴西东北海岸似乎拥有丰富的海绵动物群，但我们目前的知识集中在东南大西洋沿岸。在巴西北部海岸进行了一项调查，收集到的六种物种属于 Suberitida 目。其中两个被认为是科学新手：紫斑亚目sp。十一月，扁豆sp。十一月，四，软毛藻(软毛藻)马里亚纳桑托斯、纳西门托和皮涅罗，2018，软毛藻(H。)黑斑病德劳本费尔斯，1936 年，枳壳亚目（Duchassaing 和 Michelotti，1864 年），以及三叶草Duchassaing & Michelotti, 1864, 被重新描述。对热带西大西洋物种和四个属的模式物种进行分类比较。最后，西大西洋的识别密钥亚陨石提供物种。
