The host, Bikinia letestui letestui, a canopy tree of primary and older secondary rainforest, is known from the coastal region of Cameroon, Equatorial Guinea and Gabon (Wieringa, 1999). If O. nkoloensis is only associated with Gallastichus galls on this tree species then its distribution would be expected to follow that of its host (Rasplus et al., 2011).
