If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|W. D. Matthew and W. Granger 1924||Somewhat smaller than T. morrisi, the molars of nearly the same size, but narrower, with distinct external cingulum; anterior part of lower jaw much more slender and weak; p3 two-rooted, simple, with single acute uncompressed cusp, minute anterior basal cusp and well-developed posterior basal cingulum; p4 sub-molariform but smaller than molars, having two well-separated cusps, a lower anterir cusp and a broad low cingulum encircling posterior end of tooth.|
|A. Sulimski 1970 (Ictopidium tatalgolensis)||Incisors obliquely situated, p2 small, simple, single-rooted. The crown of p3 moderately compressed; paraconid small; metaconid present, weak; labial cingulum present delicate. Paraconid of p4 large, sharp; labial cingulum present, delicate. m1 larger or equal to m2. Protoconid of m1 well developed; metaconid lower than protoconid; hypoconulid often lacking; posterior cingulum well visible; labial cingulum well marked, below hypoconid sometimes lacking. m3 smallr or equal to m2, without hypoconulid.|
