ReferenceDiagnosis
W. W. Korth 2010Similar in size to Eumys elegans but molars wider relative to length than other species; anteroconid on m1 minute; double connection of the metalophid with the anteroconid variably present on m1 (never present in other species); lingual half of the anterior cingulum greatly reduced on m2-m3; mesolophs (-ids) minute to absent on all molars; anterocone on M1 smaller than in other species; parastyle variably present on M1 (absent in all other species); M3 slightly longer (anteroposteriorly) relative to width than in other species.
