Remarks. Five species of Tricholeiochiton are known for northern Australia, T. fidelis Wells , T. tridens Wells , T. edmondsi Wells , T. bifurca Wells , and T. jabirella Wells. Tricholeiochiton fidelis and T. bifurca were collected from far northern Cape York ( Wells & Cartwright 1993). Significantly, we record here samples of T. jabirella Wells , a species described from the Jabiru area in the north of the Northern Territory, now collected in reasonably large numbers from Boigu Island and Sesia near Weipa on the west of Cape York. The species could possibly be established in both places, or alternatively, on Boigu it might be an occasional vagrant, breeding when conditions are satisfactory; it has not been reported from New Guinea.
