Padillothorus is a genus of jumping spiders in the family Salticidae containing the single species, Padillothorus elegans. It was first described by Jerzy Prószyński in 2018,[1] and has only been found in Indonesia.[2]
In 1987, Prószyński synonymized the genus Padillothorax, first described by Eugène Simon in 1901, with Stagetillus. In 2017 and 2018, Prószyński restored Padillothorax, and separated it from the new genus Padillothorus.[1] [2] Simon had placed Padillothorax and Stagetillus in his group Bavieae,[1] now the tribe Baviini in Maddison's 2015 classification of Salticidae. Since the male of Padillothorus elegans is unknown, Prószyński considered that classification to any group of genera was impossible.[1]
