Systematics

This species described by Louis Mandelli based on specimens from Sikkim and placed in the genus ''Heterorhynchus'' which was however preoccupied leading to it briefly being placed in the genus ''Stachyrirhynchus'' by

. However the genus ''Sphenocichla'' was erected before this by Godwin-Austen and Lord Tweeddale for the Manipur or Cachar wedge-billed babbler and this species was moved to the genus ''Sphenocichla''. Molecular phylogenetic analysis indicated that the species in the genus ''Sphenocichla'' were nested amid species of ''Stachyris'' leading to them being merged into the older described genus ''Stachyris''. The species was previously known as the wedge-billed babbler and included ''Stachyris humei'' and the now separated ''Stachyris roberti'' which was earlier treated as a subspecies.

Ecology

It inhabits the understorey of broadleaf evergreen forest and bamboo at 900–1,950 m, favouring westward facing slopes in Bhutan. It occupies lower elevations only during the winter. It occurs in small parties and feeds on insects, particularly woodlice and boring beetles.
