The genus Auletta Schmidt, 1970 comprises 14 valid species, with six known from the Atlantic Ocean. The genus was previously recorded for the Brazilian coast only in 1967 from surveys in Pernambuco State. The present paper describes two new Auletta from Northeastern Brazil. Auletta akaroa sp. nov. is from Alagoas State and it has a stalked tubular shape and small sinuous styles and strongyles. Auletta laboreli sp. nov. was found in Pernambuco State and it is a sponge with a cylindrical and cavernous body composed of styles with blunt and telescopic tips and sinuous strongyles. Both new species were compared with the other valid species of Auletta. The spicule complement and external morphology of the new species are discussed.
奥氏海绵属（Auletta Schmidt，1970）包含14个有效物种，其中6个见于大西洋。该属此前仅在1967年于伯南布哥州的调查中在巴西海岸有过记录。本文描述了来自巴西东北部的两种新奥氏海绵。新物种阿卡罗阿奥氏海绵（Auletta akaroa sp. nov.）来自阿拉戈斯州，呈具柄管状，有小的弯曲花柱和强壮骨针。新物种拉博雷利奥氏海绵（Auletta laboreli sp. nov.）发现于伯南布哥州，是一种海绵，其圆柱形且多孔的主体由具钝且可伸缩尖端的花柱和弯曲的强壮骨针组成。将这两个新物种与奥氏海绵属的其他有效物种进行了比较。讨论了新物种的骨针组成和外部形态。
