Diagnoza

Differs from Messelirrisor in that the margo medialis of the coracoid bears a medial projection, the carpometacarpus lacks a processus intermetacarpalis, and the tarsometatarsus is proportionally longer; smaller from other species of genus Laurillardia and much smaller from all extant Upupidae and Phoeniculidae species (about 60% of the Abyssinian scimitarbill Rhinopomastus minor) and differs from members of these families in that the caudal margin of the sternum bears two pairs of incisions and in that processus acrocoracoideus and processus procoracoideus of the coracoid are not connected by an osseous bridge

Porównanie

As in all extant Bucerotes, there is no foramen nervi supracoracoidei; humerus is relatively short and robust, with a nearly straight shaft and in its overall proportions resembles that of Messelirrisor; carpometacarpus in general shape is similar to that in Messelirrisor, Upupidae and Phoeniculidae, with very wide spatium intermetacarpale and a strongly bowed os metacarpale minus that reaches farther distally than the os metacarpale majus and has an undulated ventral margin; as in extant Upupidae and Phoeniculidae the processus terminalis ischii of the pelvis is positioned almost at right angles to the synsacrum; three anterior toes are closely adjoined to each other may indicate the former presence of syndactyl foot, which is a characteristic feature of Upupidae, Phoeniculidae and Coraciiformes.
