Remark: This species is validated by Risch <i>et al.</i> (1979: Ref. 89459) who found the types, thus it is not a nomen nudum and the name is available.  The species is confirmed under this name by Pezold <i>et al.</i> (2006: Ref. 59380).  Therefore, the species should not be attributed to Boulenger, 1916 (as <i> Sycidium bustamantaei</i>).
Comments: Amphidromous endemics living as adults in clearwater streams from the rivers Lobe and Kribi, Southern Cameroon. Also from a stream located above several hundred meter high cascade of Rio Ilady, Bioko Island at an altitude of over 100m (Ref. 92840).
