Type species – Cystocoleus ebeneus (Dillwyn) Thwaites.
Notes – Cystocoleus was introduced by Thwaites (1849) based on C. ebeneus. Subsequently, C. niger and C. rupestris were described by Rabenhorst (1870) and Hariot (1890). However, Hawksworth et al. (2011) synonymized C. nigra under C. ebeneus and transferred C. rupestris to Racodium. Currently, Cystocoleus is a monotypic genus containing C. ebeneus.
