Diagnosis
ReferenceDiagnosis
W. Tonomori et al. 2018Allodesmus uraiporensis sp. nov. is distinguished from all other Allodesmus by having the palatine fissure (incisive foramen) that is located anterior to the canine (character 7 : 1) and an anteriorly located supraorbital process of the frontal (character 20 : 0), a developed peroneal tubercle of the calcaneum (character 98 : 1); from Al. kernensis, Al. sinanoensis Al. demerei and Al. naorai by having rounded infraorbital foramen (character 9 : 0); from Al. naorai by having M2 that is smaller than premolars (character 86 : 0); from Al. kernensis, Al. sinanoensis and Al. demerei by having a developed but not laterally exaggerated prenarial shelf (character 1:1) and a flat palate (character 12:0), posteriorly very wide palatal margins of the maxilla (character 13 : 2); from Al. packard by having the smaller size of M2 than premolars (character 86 : 0) and the small supraorbital process of the frontal (character 19 : 0).
Holotype.
