The Sikkim Wedge-billed Babbler or Blackish-breasted Babbler（Sphenocichla humei）, has been discovered and photographed during a field survey in Medog（Motuo）County, Nyingchi Prefecture, Tibet Autonomous Region, China（29°35′45″N，95°28′25″E, alt. 1437m, Fig. 1）. This is the first record of this species in China except the disputed area occupied by India. This species, together with Cachar Wedge-billed Babbler（S. roberti, Fig. 2）were once considered as two subspecies of Wedge-billed Babbler Sphenocichla humei sensu lato, but has been upgraded to a full species based on distinct morphology and vocalisations.
