Cathaica publishes original research on molluscs and related invertebrates, particularly in taxonomy, systematics, phylogeny and related fields. Revision papers, descriptions of new taxa, redescriptions of little-known taxa, illustrated keys, new national or provincial records, and biogeography are welcome. Due to the limited knowledge of Chinese molluscan taxonomy and fauna, anatomical reports, fauna investigation, and field trip results are also encouraged.

《贝类多样性研究》发行软体动物及其近缘无脊椎动物之原创研究，尤其在分类学、系统学、系统发育及相关领域。欢迎如下论文：修订、描述新分类单元、重描述鲜为人知的分类单元、图示检索表、国家级或省级新记录与生物地理。由于中国软体动物的分类学和动物区系知识有限，因此也鼓励提供解剖学报告、动物区系调查和实地野外考察记录等稿件。
