RFI status of Lesser Sand Plover C. m. atrifrons

Has there been any progress establishing the true status and distribution of C. m. atrifrons in Australia since the account published in HANZAB? The latest Clements & IOC checklists indicates atrifrons winters no closer to Australia than Sumatra and the Greater Sundas. However Pizzy & Knight digital edition include both C. m. mongolus and C. m. atrifons (sic), but supply no details on status. Also the illustrations of the two forms in non-breeding plumage seem to be reversed with atrifons (sic) shown having a white forehead and mongolus with a dark forehead. Are the P&K plates backwards?
