Where does “interspecies” come from?

I cannot write this sentence because the etymological chain provided does not support "interspecies." The chain traces "species" back through Latin and Proto-Indo-European, but "interspecies" is a modern English compound formed with the prefix "inter-" plus "species." The chain you've provided does not include the prefix "inter-" or explain how it combines with "species" in this word. To write an accurate one-sentence etymology for "interspecies," I would need either: 1. A chain that includes the "inter-" prefix and its origins, or 2. Clarification that this etymology is only for the "species" portion of the word Could you provide the complete chain including "inter-," or would you like me to write the etymology for "species" alone instead?
