Gumardee Flannery et al., 1983

Type species. Gumardee pascuali Flannery et al., 1983 Additional species. Gumardee richi sp. nov. and G. springae sp. nov.

Revised generic diagnosis. Potoroine with elongated and narrow sectorial P3/p3 aligned with molar row, buccal and lingual cingulae on the medial portion of P3, concave lower molar row and convex upper molar row in dorsoventral plane, buccinator sulcus on the dentary, reduced m4/M4 (smaller than m3/M3), and partially lophodont (see definition in methods) molars.

Species of Gumardee differ from all hypsiprymnodontids in having elongated sectorial premolars, aligned with the tooth row, and having partially lophodont molars. They differ from Wabularoo , Ganguroo , balbarids, sthenurines, macropodines and lagostrophines in having a greatly reduced M4, concave lower molar row and convex upper molar row in dorsoventral plane and having partially lophodont molars. They differ from Purtia, Ngamaroo , Bulungamaya , Wakiewakie and all potoroines, in buccal and lingual cingulae on the medial portion of P3 and being much larger in size.
