A gall midge that induces upwardly folded leaf-margin galls on Quercus serrata, Q. mongolica and Q. dentata (Fagaceae) in Japan and South Korea is described as Macrodiplosis selenis sp. n. (Diptera: Cecidomyiidae). M. selenis is distinguished from Palaearctic congeners by a combination of morphological characters. Genetic differences supported the result of morphological comparison and indicate...

The genus Trachionus Haliday, 1833 (Hymenoptera, Braconidae, Alysiinae, Dacnusini) is reported for the first time from China. The genus is represented by four new species from Shaanxi province (NW China), which are described and illustrated. An identification key to the species in China is presented, a key to the genera of the Trachionus group and notes on the relationships with other Palaearct...

The genus Polychrysia is comprised of seven species separated into three species groups. Six of the seven species are distributed in the Palaearctic region and one of these six species has a Holarctic distribution. The genus has been discussed in detail in monographs by Goater et al. (2003) and Ronkay et al. (2008). A new species of Polychrysia was discovered during an expedition studying the n...

Systematic information on the rarely collected Holarctic platypezid genus Seri Kessel & Kessel is reviewed.
