Diagnosis
ReferenceDiagnosis
N. R. Longrich et al. 2013Distinguished from Leptorhynchos elegans by a more anteriorly projecting tip of the beak, a strongly rounded anteroventral margin of the symphysis, lateral occlusal margins of the dentaries not as strongly divergent in dorsal view, with the tip of the beak being narrower and more spoon-shaped in dorsal view.
