The diastema in front of the premolars is longer in the living Equidae than in their extinct allies.
Three specimens lack a diastema and 17 specimens have a diastema.
The teeth are in a continuous series; no diastema or maxillary step is evident.
The canines were not greatly enlarged, and no diastema separated any of the teeth.
Between them and the incisors above, and between the canine and the anterior pre-molar below, occurs a gap (or diastema).
Homalodontotherium owes its name to its even row of teeth without a diastema.
The small size of the canine and of the first premolar produces a diastema in the tooth series.
On the mandible the great length of the diastema between the incisors and premolars is a Giraffine characteristic.
Then the absence of a diastema in the tooth series, coupled with the presence in Macrauchenia of a complete dentition.
In combination with this characteristic, it often happens that there is a diastema next to the canine.
