Sickius is a genus of tarantulas. It has a single species, Sickius longibulbi. It is endemic to Brazil.
== Taxonomy == The species S. longibulbi was described in 1948 by Benedict A. M. Soares and H.F. de A. Camargo. However, Robert Raven put it in the genus Hapalotremus, on account of a similar double-branched tibial spur, though the holotype was missing at the time. It was restored to the genus Sickius in 2002 by Rogério Bertani, who claimed it lacked urticating hair and any keels on the embolus therefore it was impossible for the genus to be a member of the Theraphosinae.
