In principle, it is a dictionary error, since xenocida is "genocidal" in Galician. But, although it is not incorporated into the Castilian dictionary, it can be a neologism from the Greek 958; 949; 957; 959; 962; (xenos "foreign") and fallen Latin ("to cut off, to kill"), for those who murder foreigners for the mere fact of being so. However the use may be a little wider thanks to the science fiction novel Xenocide ("Ender, the Xenocidal", Orson Scott Card, 1991) where the crime is committed against an entire extraterrestrial species.
