Relatively recent phylogenetic research as well as nomenclature revisions have clarified the relationships of many North American jumping spiders. A piece of this work involves the taxonomist's focus on synonyms (duplicate names for the same species) and priority (chronology of published names for a given species). Evarcha is a large genus with representatives in Asia, Africa, and Europe. The nomenclature of the sole eastern North American species has been the topic of some debate, with one authority suggesting this spider is E. falcata, occurring here and in Europe. This designation is now thought to be incorrect and "our" spider is the endemic Evarcha hoyi. Edwards, 1980; Edwards, 2008.
