Sponges (phylum Porifera) are common inhabitants of kelp forest ecosystems in California, but their diversity and ecological importance are poorly characterized in this biome. Here I use freshly collected samples to describe the diversity of the order Scopalinida in California. Though previously unknown in the region, four new species are described here: Scopalina nausicae sp. nov., S. kuyamu sp. nov., S. goletensis sp. nov., and S. jali sp. nov.. These discoveries illustrate the considerable uncharacterized sponge diversity remaining in California kelp forests, and the utility of SCUBA-based collection to improve our understanding of this diversity.

来自南加州的四个新 Scopalina：来自温带东太平洋的第一个 Scopalinida（Porifera：Demospongiae）

海绵（Porifera 门）是加利福尼亚海藻森林生态系统的常见居民，但它们的多样性和生态重要性在该生物群落中的特征很差。在这里，我使用新鲜收集的样本来描述加利福尼亚州 Scopalinida 目的多样性。尽管该地区以前不为人知，但这里描述了四种新物种：Scopalina nausicae sp。11 月., S. kuyamu sp. nov ., S. goletensis sp. 11 月., 和S. jali sp. 十一月 . 这些发现说明了加利福尼亚海藻森林中剩余的大量未表征的海绵多样性，以及基于 SCUBA 的收集对提高我们对这种多样性的理解的效用。
