Anomoneura taiwanica sp. nov. (Hemiptera, Psylloidea, Psyllidae, Psyllinae) is described based on samples from Taiwan that were previously misidentified as A. mori Schwarz, 1896. Morphological and genetic differences between the two species, as well as their distribution, are detailed and discussed. Comments on the pest status of Anomoneura spp. in East Asia are also provided. [ABSTRACT FROM AUTHOR]

The material disparity with the West, and the havoc wreaked in the period of Japanese imperial encroachment on Chinese territory and autonomy after the First Opium War, have shaped and guided China's collective memory and its shared desire of national rejuvenation to this day. In tracing the deeper historical roots of what Xi Jinping contemporarily frames as a "Chinese dream" of "wealth and power," the article discerns key actors, events, and organizing principles in a long process toward restoring China's deemed rightful place in the regional system. Taking into account the region-specific socio-historical complex of China and East Asia, and further exploring the parameters of an International Relations theory with "Chinese characteristics," the article's comparative historical analysis details how China's leaders have chosen to mobilize the nation's "domestic resources" in their common pursuit of national rejuvenation. Providing greater insight into how and according to which interlinked domestic and foreign explanatory markers this is attained, the article argues that we are currently in the last phase of rejuvenation and advances implications for China's further trajectory.

Pear psyllids are major pests and the causal agents of pear decline disease in orchards. In the past two decades, their outbreaks have raised issues pertaining to invasions and taxonomic identification of the dimorphic Cacopsylla chinensis (Yang and Li) in East Asia. The present study elucidated, as an aid to quarantine management, the invasive origins, differentiation history, and putative gene flow and hybridization between C. chinensis and its sibling species Cacopsylla jukyungi (Kwon). Analyses revealed that the ancestors of C. jukyungi might have diverged from C. chinensis approximately 3.5 million yr ago (Mya) and that differentiation between C. chinensis lineages I and II probably occurred 1.5 Mya. The known overlapping distribution of C. chinensis and C. jukyungi in northeastern China and the two C. chinensis lineages in the Bohai Rim region and Taiwan could be attributed to recent population expansion after the Last Glacial Maximum and/or anthropogenic activities. Analyses of the nuclear gene demonstrated that frequent gene flow between the two C. chinensis lineages and the paraphyletic relationship between C. chinensis and C. jukyungi might be caused by incomplete lineage sorting or hybridization events. On the basis of the current distribution, it is evident that C. jukyungi is not present in middle-southern China, whereas C. chinensis is not distributed in Japan and Korea. Preventing new invasions of Cacopsylla psyllids among geographic regions through the transportation of pear scions is thus pivotal in East Asia, particularly for the possible genetic exchanges among differentiated lineages after secondary invasion events.
