《無脊椎動物分類學》(前身為《無脊椎動物分類學》)在世界范圍內發表了關于無脊椎動物分類學和系統學的原創和重要貢獻。論文提供了明確定義的分類群的綜合或修正處理，并包含了系統發育、生物地理學和/或該群的生物多樣性和一般生物學的其他方面的信息。如果在工作中大量突出某些方面的重要性，也可以考慮對具有養護、經濟、醫療或獸醫重要性的選定物種的系統學的貢獻。鼓勵發表有關無脊椎動物系統生物學的簡短、一般性論文:方法論、理論系統學、分類學、系統學、分子生物學和生物地理學。還積極尋求對一般無脊椎動物系統學的關鍵綜述，包括創新的數據或對當前理論的概述。

Invertebrate Systematics (formerly Invertebrate Taxonomy) publishes original and significant contributions on the systematics and phylogeny of invertebrates worldwide. Papers provide comprehensive or revisionary treatments of clearly defined taxonomic groups and contain information on the phylogeny, biogeography and/or other aspects of biodiversity and general biology of the group. Contributions on the systematics of selected species that are of conservation, economic, medical or veterinary importance may also be considered, if these aspects are substantially highlighted in the work. Short, general papers, pertinent to invertebrate systematic biology are encouraged on: methodology, theoretical systematics, cladistics, phylogeny, molecular biology and biogeography. Pivotal reviews of general invertebrate systematics, containing innovative data or overviews of current theories, are also actively sought.
