Abstract:
ABSTRACT. Members of the subfamily Deltocephalinae include many vector species
transmitting pathogens among economically important crops. Species of ten genera
belonging to seven tribes namely, Exitianus Ball, Nephotettix Matsumura, Deltocephalus
Burmeister, Hecalus Stål, Balclutha Kirkaldy, Cicadulina China, Hishimonus Ishihara,
Orosius Distant, Changwhania Kwon and Doratulina Melichar were detected in a survey
carried out during 2007-2008 in Mid Country associated with the vegetable ecosystems of
Sri Lanka. An illustrated dichotomous key based on the morphology and genitalia characters
is presented here for easy identification of field collected leafhoppers at generic level.
