Type.

This monotype is perhaps most like Sciitalopus in general 

 appearance, but has, although to a lesser degree than Acrajdernis, a 

 similar development of the culmen into an oval plate. The hind 

 claw is moderately long and curved. The tail is rather short and 

 much rounded. 



Triptorhinus is confined to Southern Chili.
