runkoiset
Could you clarify what you mean by "runkoiset"? In Finnish biology, there isn’t a widely recognized, current taxonomic group consistently referred to as "runkoiset," and the term could refer to different concepts depending on context (historical usage, a specific discipline, or a translation of another term). If you can specify the intended scope (for example, a particular clade or a historical usage in Finnish texts) or provide a source, I can write a concise, neutral wiki-style article under 300 words.
