Presently considered a synonym of O. xanthosticta and is an acceptible name for the species that is common around Auckland (Type locality for O. piciceps is either Howick or Manaia - a lectotype is yet to be selected). It is known from Whangarei and its vicinity but has yet to be found in the Bay of Islands area the presumed type locality for O. xanthosticta . It tolerates urban environments.
