This genus appears to be closely allied to _Prosobonia_, but has a much
shorter hind toe. Its colouration is very different, and quite that of a
Sandpiper, while the pattern of _Prosobonia_ is most singular. Seebohm
placed _Aechmorhynchus_, together with _Prosobonia_, in the genus
_Phegornis_.
We know only one species.
