The leafhopper genus Cornicola Ohara & Hayashi, previously recorded from Japan, is recorded from China for the first time and a new species, C. maculatus Xu, Dietrich & Qin, sp. nov., is described and illustrated, including its color polymorphism. This genus has male genitalia and hind wing venation similar to those found in Empoascini but it is more appropriately placed in Dikraneurini. A key to species of Cornicola is given together with a key to the genera of Dikraneurini from China.

Libaneuphoris jantopi gen. et sp. n., Burmipachytrocta singularis gen. et sp. n., and Atapinella garroustei gen. et sp. n., three fossil taxa assigned to Pachytroctidae (Psocodea, Troctomorpha), are described and figured from the Cretaceous ambers of Lebanon and Myanmar. A new subfamily Libaneuphorinae subfam. nov. is proposed to embrace the Lebanese fossil Libaneuphoris jantopi . The positions of the new taxa are discussed and the fossils are compared to other pachytroctids. The described species represent the earliest records of the family Pachytroctidae. A checklist of all known Pachytrocidae is given.

The first representative of the booklouse genus Embidopsocus Hagen (Nanopsocetae: Liposcelididae) is documented from the blaue Erde of northern Europe. Embidopsocus pankowskiorum Engel, new species, is similar to the related E. saxonicus Günther from the Bitterfeld deposits (so-called ‘Saxonian amber’) and E. eocenicus Nel et al. from Oise amber, but differs in details of antennal structure, setation, wing venation, and size. The species is described and comments made regarding its character affinities to other fossil liposcelidids.

Two new species and genera of minute, coleopteriform psocopterans, family Sphaeropsocidae (Nanopsocetae), are described from fossils preserved in Cretaceous ambers: Sphaeropsocoides canadensis Grimaldi and Engel, n.gen., n.sp., from the Campanian of western Canada; and Sphaeropsocites lebanensis Grimaldi and Engel, n.gen., n.sp., from the Neocomian of Lebanon. These are the first described Mesozoic species of the family. Sphaeropsocus kuenowii Hagen in midEocene Baltic amber is redescribed in detail. The 14 described Recent species of the family (in the genera Sphaeropsocopsis and Badonnelia) have natural distributions that are largely restricted to southern portions of the Southern Hemisphere, but Eocene and now Cretaceous fossils reveal a formerly global distribution of the family. Hypothesized relationships of the five genera indicate basal positions of the fossil genera, and probably an entirely Tertiary age of the Recent genera Sphaeropsocopsis and Badonnelia, which would thus be too young for these two genera to have been affected by gondwanan drift.
