Calcareous sponges from the Lesser Antilles were recently inventoried and several specimens morphologically resembling species of the genus Ascoleucetta were collected. Morphological and molecular (C-LSU and ITS) analyses indicated that these specimens from the Lesser Antilles constituted a new genus. They lack the conspicuous and very characteristic ornamentation of the inhalant apertures found in two out of three species of Ascoleucetta, including the type species A. compressa. In the molecular analyses, the specimens clustered as an independent lineage, distant from the clade of A. compressa. Based on these results, we decided to erect a new genus, Bidderia gen. nov., whose type species is Bidderia bicolora gen. nov. sp. nov. Considering this new discovery, we are proposing to transfer the species A. amitsba to the genus Bidderia gen. nov. and to rediagnose Ascoleucetta.
最近对小安的列斯群岛的钙质海绵进行了清查，并收集到了几个形态上类似于Ascoleucetta属物种的标本。形态学和分子（C-LSU和ITS）分析表明，这些来自小安的列斯群岛的标本构成了一个新属。它们没有Ascoleucetta三个物种中两个物种（包括模式种A. compressa）所具有的明显且非常独特的进水孔装饰。在分子分析中，这些标本聚为一个独立的谱系，与A. compressa的分支相距较远。基于这些结果，我们决定建立一个新属，Bidderia属新属，其模式种为双色Bidderia属新属新种。考虑到这一新发现，我们提议将A. amitsba物种转移到Bidderia属新属，并对Ascoleucetta进行重新诊断。
