Arucillus is a genus of harvestmen in the family Cosmetidae with two described species (as of early 2025). All species are from Central America or South America. An overview of the wider phylogeny was stated by Medrano et al. (2024) favoring a placement in Metergininae but acknowledging that Arucillus appeared among Libitiinae in all other analyses, in some cases appearing allied to some externally similar species from Mexico and Antilles, those currently in the genera Holovonones and Vonones.
