Wayanad laughingthrush 
(Khướu bụng vằn, Pterorhinus delesserti)
Once placed in Crateropus, Dryonastes or Garrulax, Ianthocincla.

The Wayanad laughingthrush (Pterorhinus delesserti) is a species of laughingthrush in the family Leiothrichidae. It is endemic to the Western Ghats south of Goa in India.

Some resemblance to the rufous-vented laughingthrush (Pterorhinus gularis) of northeastern India which has a yellow throat. 
Some older treatments considered lumped delesserti with gularis.

The ranges of delesserti and gularis are widely disjunct but museum specimens can be told apart by the pale lower mandible of delesserti unlike the all dark bill of gularis. 
The tail is uniformly coloured and is darker than the back in delesserti while that of gularis is pale with rufous outer tail feathers. 
The chin is yellow in gularis while white in delesserti. 

Leiothrix Leiothrichidae Ancient Greek leios meaning "smooth" and thrix meaning "hair".
The name of the genus combines the Ancient Greek pteron meaning "feather" with rhinos meaning "nostrils".
The specific epithet was chosen to honour the French naturalist Adolphe Delessert who had collected specimens from near Kotagiri in the state of Tamil Nadu, India.
