Subfamily PLECTROPTERINAE.
The distinguishing features of this subfamily are the rather long hind toe, without lobes and the neck shorter than the body ; the upper plumage, especially in the male, is more or less glossy; the tail is rather long.
Three genera are represented in India, though two of these,. Asarcornis and Rhodonessa, which are peculiar to our area, are represented by single species only.
