Anheteromeyenia Schröder, 1927 (Spongillidae) was erected to comprise species of Heteromeyenia Potts, 1881 without microscleres. Until now, only four species of Anheteromeyenia are known, three from the Neotropical Region (A. cheguevarai, A. ornata and A. vitrea) and A. argyrosperma from the Nearctic Region. In the present study, we describe a new species of Anheteromeyenia from the Neotropical Region, which differs from other congeners in having only one category of megascleres, exclusively smooth oxeas. An identification key to species of Anheteromeyenia and an emended diagnosis of the genus are provided.
异形美星海绵属（Anheteromeyenia）由施罗德于1927年建立（淡水海绵科），包含1881年波茨所描述的无小骨针的异形美星海绵属（Heteromeyenia）物种。到目前为止，已知的异形美星海绵属仅有4个物种，其中3个来自新热带地区（切·格瓦拉异形美星海绵、饰边异形美星海绵和透明异形美星海绵），还有1个北极地区的银籽异形美星海绵。在本研究中，我们描述了一种来自新热带地区的异形美星海绵属新物种，它与其他同属物种的不同之处在于只有一类大骨针，且全为光滑的单尖骨针。文中还提供了异形美星海绵属物种的鉴定检索表以及该属的修订诊断。
