The genus Pnoepyga contains two Wrens which are characterized by an extremely short tail of only six feathers; this short tail is, moreover, entirely concealed from view by the long and very ample rump-feathers. In other structural characters the genus resembles Urocichla.
The sexes differ considerably in colour, and the young are without the markings of the adult. Both species are resident on the Himalayas and the hill-ranges of Burma.
