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.

---|---|---|
M. R. Dawson 2001 | Small- to medium-sized ischyromyid rodents; dental formula 1/1, 0/0, 2/1, 3/3. Lower molars have well-developed anterior cingulum; at least in early wear stages, anterior cingulum is separated by a buccal groove from the protoconid; buccal end of anterior cingulum may be cuspate; trigonid short anteroposteriorly with small trigonid basin; tendency toward strong transverse component in lophids of
lower molars, with metalophid and hypolophid from short to complete; mesoconid rounded; entoconid separated by groove from posterolophid. Upper molars have distinct hypocone; protoloph and metaloph directed toward protocone. Occlusal pattern on lower molars varies from simple (Microparamys) to complicated by numerous small folds and crenulations (Lophiparamys, Mattimys). |
