Kāne'ohe Bay has historically been known for the introduction of alien species from the Caribbean and the Western Indo-Pacific. Recent efforts that explore the reef cryptofauna have shown that in addition to the diversity of non-indigenous species, patch reef environments are rich with undescribed species. Here we integrate molecular phylogeny and systematics to distinguish introduced species from those that are potentially native or endemic. We focus on the order Tetractinellida and document the potential transoceanic dispersal of from the Caribbean to Hawai'i. Our integrative approach allowed us to describe new species of ( sp. nov., sp. nov., sp. nov., sp. nov., sp. nov.) and one new species of ( sp. nov.); all collected from the reef cryptofauna the use of Autonomous Reef Monitoring Structures. Specimens were barcoded using 28S and COI molecular markers, providing insights into the phenotypic plasticity of sponges and the phylogenetic placement of these new species based on morphological characters. Using both molecular phylogeny and traditional taxonomy enhances the accuracy of species identification and classification, contributing to a broader understanding of sponge biodiversity within the Hawaiian archipelago.
卡内奥赫湾一直以来因从加勒比地区和西印度洋 - 太平洋引入外来物种而闻名。最近对珊瑚礁隐生动物群的研究表明，除了非本土物种的多样性外，斑块礁环境中还存在大量未被描述的物种。在这里，我们整合分子系统发育学和分类学，以区分引入物种与可能是本土或特有物种。我们专注于四轴海绵目，并记录了[物种名称]从加勒比地区到夏威夷的潜在跨洋扩散情况。我们的综合方法使我们能够描述[海绵物种名称]的新物种（[具体新物种1]新种、[具体新物种2]新种、[具体新物种3]新种、[具体新物种4]新种、[具体新物种5]新种）和一种[另一种海绵物种名称]的新物种（[具体新物种6]新种）；所有这些物种均使用自主礁体监测结构从珊瑚礁隐生动物群中采集。使用28S和COI分子标记对标本进行条形码分析，基于形态特征深入了解了海绵的表型可塑性以及这些新物种的系统发育位置。结合分子系统发育学和传统分类学提高了物种鉴定和分类的准确性，有助于更广泛地了解夏威夷群岛内的海绵生物多样性。
