Puparia and third instars of a new whitefly, Aericerus meghalayensisgen. et sp. nov. infesting Terminalia calamansanai (Blanco) (Combretaceae) leaves are described from Barapani, located in the state of Meghalaya in North-East India. The florate-shaped wax secreting geminate pores and submarginal sieve plates are reported for the first time from whitefly puparia. Puparia of the new genus differ from closely related genera, Aleuroclava Singh and Trialeurolonga Martin in having submargin demarcated from the dorsal disc, longitudinal and transverse moulting sutures reaching submarginal ridge, prominent tracheal folds, and a groove demarcating narrow submargin ventrally; it also differs from the former genus in having wax secreting glandular pores with accompanying sieve plates on the submargin, and from the latter genus in puparial size, smooth margin and in lacking submarginal papillae. The new taxa are described with camera lucida drawings, images of habitus, holotype puparium and third instar, and scanning electron microscope photomicrographs.
