Published online by Cambridge University Press: 10 July 2009
Extract
The species of the genus Pyrilla Stål (Fulgoroidea: Lophopidae) found in India and Ceylon are reviewed on the basis of population samples from different localities. It is considered that two polytypic species are present: P. perpusilla (Wlk.), widespread in India and now recognised as extending to Ceylon and to Thailand, and P. aberrans (Kby.) (sensu stricto), formerly regarded as being confined to Ceylon, but now found to occur also in south India. Ten geographical subspecies of the former and five of the latter are described and named.
