Puparia and third instar of a new diminutive whitefly, Regiominutus ventralis gen. et sp. nov. found infesting underside leaves of Aglaia elaeagnoides (A. Juss) (Meliaceae) on the Andaman Islands, India, are diagnosed, described and discussed. Regiominutus gen. nov. differs from allied genera, Aleuroclava Singh, Aericerus Dubey, Aleuroparvus Dubey, Aleuropleurocelus Drews and Sampson and Tetralicia Harrison in having a submarginal ventral groove, from the former two in having a deflexed submargin and smaller ventral surface and from the latter two in having a caudal furrow. Affinities and differences of the new genus shared with related genera are discussed. Puparium characters observed in slide mounts versus scanning electron microscope (SEM) images are presented. Line drawings, habitus images and SEM, microphotographs of the type specimens are given for the new taxa. This is the first whitefly species to be recorded from this host plant.

Puparia of a new whitefly genus and species, Margaritaplena ovatagen. et sp. nov. found feeding on the underside of the leaves of Combretum sp. (Combretaceae) are described from the Andaman Islands, India. It differs from the allied genera, Asialeyrodes Corbett, Icfrealeyrodes Dubey and Sundararaj, and Vasantharajiella PMM David in shape, the large-sized geminate pores, and thoracic and caudal tracheal pores comprising microtubercles, and are inset from the margin, and also from Asialeyrodes in a complete submarginal furrow, and in lacking the first abdominal setae and caudal furrow. Line drawings, images for the habitus, types, and scanning electron microscope photomicrographs are provided for the new taxa. An identification key to puparia differentiating the new genus from related Indian Aleyrodinae genera is given. [ABSTRACT FROM AUTHOR]

A new whitefly species, Pealius satakshiae Dubey, found infesting Quercus leucotrichophora A. Camus (Fagaceae) in the Chail Wildlife Sanctuary, Himachal Pradesh, India, is described. Puparia of the new species differ from described Pealius species in being larger in size, having a differentiated cephalus, rhachisform abdomen and reduced abdominal segment VII, and lacking the first abdominal setae. Puparial characteristics for the genus Pealius Quaintance and Baker in relation to new species are discussed. Camera lucida drawings, images of habitus and holotype, and scanning electron microscope photomicrographs are provided. [ABSTRACT FROM AUTHOR]
