the rules of the International Code of Zoological Nomenclature; the publication of Sicariidae in 1880 predates the publication of Loxoscelidae in 1893, and the older name therefore has priority whenever the two are considered to be synonyms. The World Spider Catalog treats Loxoscelinae as a subfamily of Sicariidae, though some sources still recognize Loxoscelidae as a separate family (e.g.,). A phylogenetic study in 2017 showed that the African species of Sicarius were distinct, and placed them in the revived genus Hexophthalma. The relationship found between the genera is shown in the following cladogram: Genera , the World Spider Catalog accepts the following genera: Hexophthalma Karsch, 1879 – Namibia, South Africa Loxosceles Heineken & Lowe, 1832 – South America, North America, Asia, Africa, Central America, Caribbean, Finland, Australia Sicarius Walckenaer, 1847 – South America, Central America See also List of Sicariidae species References External links Araneomorphae families Taxa named by Eugen von Keyserling
