Diagnosis: The male can be distinguished from all other theraphosids, except some Hapalopus species, by the presence of a paraembolic apophysis on male palpal bulb (Figs 1– 22). Male Cyriocosmus can be distinguished from Hapalopus by the divergent branches on the tibial apophysis (Figs 23–33). The female can be distinguished from all other theraphosid species by having a sinuous or spiral spermathecae neck with a convex base (Figs 34–39).
