Species­group of Bemisia tabaci (Gennadius, 1889)

DISTRIBUTION. Cosmopolitan, but only under cover in cooler temperate areas.

HOST PLANTS. Filicopsida ­ Gleicheniaceae: Dicranopteris ? linearis; also highly polyphagous on Angiospermae.

COMMENTS. We ae only aware of a single record of this major pest species­group from a fern, and it concerns just two puparial specimens collected in the Genting Highlands, peninsular Malaysia (BMNH), on a fern species that rapidly colonises newly cleared land in the tropics. The vasiform orifice is a little broader than is typical for B. tabaci, but the geminate pore/porette distribution and stout caudal setae indicate inclusion in this important species­group.
