REMARKS

Dumitrica in De Wever et al. (2001) regards Apophysisphaera Won, 1997 as a junior synonym of Entactinia Foreman, 1963 , which itself is a junior synonym to Stigmosphaerostylus Rüst, 1892 . The type species, E. profundisulcus Aitchison, 1993 is considered to be a junior synonym of Stigmosphaerostylus ornata (nom. corr. ornatus) Hinde, 1899 ( Aitchison & Stratford 1997: 380).
