While this may look like a scientific name for a spider, there is no species with this name. In fact, many spiders have falcatus as their species name, not their genus name (Scientific names are written: Genus species). Aranei is a name used for the category of spiders in early taxonomic history (1700s CE) and still seems to be used in Russia and Far East Russia as a categorical name for spiders. Aranei is found in association with the Family Araneidae, the category known as the orb weavers. Falcata is also the name for a Spanish sword. Falcatus Aranei is Latin for "sickled-shaped spiders" (falcatus "sickle-shaped or curved" + aranei "spiders"), but can be interpreted to mean a spider with a sickle-shaped appendage.
