Taxonomy
The genus was first described by Hugo Albert Tullgren in 1910 using the genus name Sancus.[1][2] However, this name was already in use for a genus of skippers.[3] In 1992, Jörg Wunderlich erected a new genus Leucognatha for a species from the Azores.[4] In 2006, Leucognatha was synonymized with Sancus. In 2022, it was recognized that Sancus was not an available name for the spider genus, so that Wunderlich's Leucognatha became the correct name.[1]
