Diagnosis
ReferenceDiagnosis
T. H. Worthy and W. E. Boles 2011A flightless rail having the diagnostic characters of the genus Australlus that differs from A. disneyi by its considerably larger size (humeral proximal width and distal width are 117.5% and 116.5%, respectively, of the largest values for A. disneyi) and by having the humeral facies bicipitalis in the area overlying the corpus depressed into a distinct depression relative to the intumescentia humeri and caput humeri; a near obsolete sulcus lig. transversus that is separated from the incisura capitis by a caudocranially thicker ridge; a less prominent proc. supracondylaris dorsalis; and proc. flexorius extending markedly further distally than the condylus ventralis.
