TYPE LOCALITY: Papua New Guinea , Western Prov., Sturt Isl Camp, Fly River (N bank), near Fairfax Isis, sea level . DISTRIBUTION: Known only from the type locality along lower Fly River ; limits unknown. COMMENTS: The diagnostic traits Tate and Archbold (1938) used to separate this species from the other two identify a lowland population of Leptomys that shows no morphological intergradation with samples of either L. elegans or L. ernstmayri . This species is still known only by the four examples in the type series.
