Anil
Kumar Dubey, Chiun-Cheng Ko, and Baliah Vasantharaj David (2008) The
whitefly genus Singhius
Takahashi (1932) is revised based on examination of types and other
determined specimens. Singhius
ehretiae Jesudasan and David is synonymized with S. hibisci (Kotinsky). Adult
morphology is provided for the first time for S. hibisci. Notes on
dimorphism, intraspecific variations, and new hosts are given.
The study led to a generic redescription, and supports Singhius as a full genus; species
diagnoses and an identification key to puparia are given.
Key words: Singhius, Morphology, Variation,
Dimorphism, Key.
