The plant-louse subfamily Miralinae, as a bizarre extinct psylloid lineage displaying some unique body structures and wing characteristics, was recently erected on the basis of the monotypic genus Mirala reported in mid-Cretaceous Kachin amber of northern Myanmar. Herein, Burmala liaoyaoi gen. et sp. nov., as the second genus and species of Miralinae, is described and illustrated from the same amber biota. The new genus is discriminated from Mirala by possessing elongate compound eyes, lateral ocelli close to anterior margin of compound eyes, and forewings with the wing tip at ending of vein M, very thick and long bScP, complete CuA2 and CuP, etc. Our new finding provides additional morphological information for the intriguing Miralinae, further adding the biodiversity and disparity of this plant-louse subfamily.

Four new protopsyllidioid species, Paraprotopsyllidium spinosum gen. et sp. nov., Angustipsyllidium minutum gen. et sp. nov., Burmapsyllidium setosum gen. et sp. nov., and Maliawa akrawna gen. et sp. nov. are described from the mid-Cretaceous Burmese amber, and assigned to a new family, Paraprotopsyllidiidae fam. nov., that we establish. These taxa are characterized by their narrowed fore and hind wings, bearing a fringe of long setae; the possible functions of these bristles are explored in this paper. The population dynamics, the potential diet and feeding behavior and the biogeographical distribution of this family are briefly discussed.

Whiteflies are abundant and highly diverse in mid-Cretaceous Kachin amber, but only three taxa have been reported to date: Burmoselis evelynae and Paraburmoselis kachinensis in the extinct subfamily Bernaeinae, and ‘Aleurodicus’ burmiticus with generic and subfamilial assignment doubtful. A new genus and species, Burmodicus cretaceus gen. et sp. nov., is herein described and illustrated on the basis of a new whitefly in Kachin amber, and the new taxon is tentatively assigned to the subfamily Aleurodicinae. In addition, the nomenclature, homology and evolution of aleyrodid wing venation are briefly discussed.

The first jumping plant-louse from mid-Cretaceous Burmese amber is described as Mirala burmanica gen. et sp. nov. The absence of modified hind legs places the new taxon near the Mesozoic Liadopsyllidae (1 genus, 12 species) and Malmopsyllidae (4 genera, 4 species). The latter is defined by the presence of a pterostigma in the fore wing but is otherwise morphologically heterogeneous. Mirala has a pterostigma but shares also characters with Liadopsyllidae. It is concluded that Malmopsyllidae is polyphyletic and following synonymy is proposed: Liadopsyllidae = Malmopsyllidae syn. nov. Mirala differs from the other five Mesozoic psylloid genera in the straight, subparallel veins Rs, M and Cu1a, the unforked vein M in the fore wing and the straight vein Cu1b which is directed toward the wing base. A key is provided for the identification of the genera of Liadopsyllidae. The new taxon described here represents only the third specimen of Liadopsyllidae preserved in amber, and the fourth species from the Cretaceous (the majority being Jurassic). A member of the plant family Lauraceae is discussed as a possible host plant for the psyllid lineage in Burmese amber.

Four new, monotypic genera of Aleyrodidae from the Lower Cretaceous Lebanese amber are described: Shapashe aithiopa gen. sp. nov.; Milqartis azari gen. sp. nov.; Aretsaya therina gen. sp. nov.; and Yamis libanotos gen. sp. nov. All new taxa represent subfamily Aleurodicinae. The key for identification of genera of Aleurodicinae from the Lebanese amber is provided. The morphological features of newly established taxa are discussed. The importance of the fossils for phylogenetic, evolutionary and ecological studies is presented.

Eomatsucoccus andrewi sp. nov. (Hemiptera: Sternorrhyncha: Coccinea: Matsucoccida) has been established on the basis of a wing impression from the Lower Weald Clay (Hauterivian, Lower Cretaceous) at Keymer Tileworks, West Sussex, southern England. It differs from the other two Lower Cretaceous species, E. sukachevae Koteja and E. popovi Koteja, in wing size (c. 3.3 mm long) and shape (gradually tapering towards apex). The taxonomy and palaeontology of the matsucoccids are discussed.
