The genus Parasudra Schmidt syn.nov.is found to be a new junior synonym of Balala Distant,and its type species Parasudra sumatrana Schmidt is transferred to Balala as a new combination,Balala sumatrana(Schmidt)comb.nov.Pseudosudra Schmidt syn.nov.is proposed as a new junior synonym of Sudra Distant,and Pseudosudra borneensis(Schmidt)is recovered as Sudra borneensis stat.retr.Sudra insularis Schmidt syn.nov.is found to be a junior synonym of Sudra notanda Distant.A new species Kalasha brachyala sp.nov.is described,and Balala sumatrana(Schmidt)comb.nov.and Sudra borneensis stat.retr.are redescribed.Figures for all species are provided.
The Nematus wahlbergi group from China is revised.Two species are described as new:N luyaensis Liu,Li&Wei sp.nov.and N.rubifemoratus Liu,Li&Wei sp.nov.from the Chinese Provinces of Shanxi and Gansu,respectively.A key to all Chinese species of the Nematus wahlbergi group is provided.
Medina Robineau-Desvoidy,1830(Diptera:Tachinidae)belongs to the tribe Blondeliini in the Exoristinae.One new species of the genus from the Yintiaoling National Nature Reserve,Wuxi County,Chongqing,China was found and is described:Medina wuxiensis Zhang&Dong sp.nov.

There is well-documented evidence for an ongoing decline in flying insect biomass.The author briefly summarizes the 26-years of Malaise trap data(Hallmann et al.2017)from German nature reserves.An additional 10-year sweep-net study published by Seibold et al.(2019)found an even greater decline in insects on German forests and grasslands.Additional studies are cited that involve a variety of sampling methods and target butterflies,moths,aphids and other insects.Some studies go back to 1968.The results show declines of 28 to 46 percent.
A new genus, Sinogodavaria gen. nov., with two new species, S. multiformis sp. nov. and S. tenebrosa sp. nov., is described from China. It belongs phylogenetically to the Hypocera group of genera. The species Latiborophaga bathmis Liu is transferred to the new genus. A key to species of the new genus is presented.
Two new species of the genus Togoperla are described from Guangxi,China:T.caii sp.nov.and T.hippata sp.nov.Togoperla perpicta Klapálek,1921 and T.triangulata Du&Chou,1999 from the same region are diagnosed and re-described.The taxonomic relationships are discussed with related congeners.
A new species,Simulium(Simulium)setiferorum sp.nov.,is described from Yunnan Province,China.This species is assigned to the venustum species-group in the subgenus Simulium and is morphologically most similar to S.(S.)xinbinen Sun,1994 from Liaoning in China.However,it is clearly differentiated by the shape of the genitalia.A key to the female adults of the venustum species-group of China is provided.
Three new species of Janus Stephens are described from Zhejiang Province,China:Janus dianban Wei sp.nov.,J.infuscimarginatus Wei sp.nov.and J.xanthoscutella Wei sp.nov.A key to four Janus species from Zhejiang Province is provided.Type materials are deposited in the Asian Sawfly Museum,Nanchang,China.
The mitogenome is a double strand molecule that has become an extensively studied molecular marker used in the study of the phylogeny of insects.A recent study investigated the mitogenomes of Planococcus citri(Risso,1813)and Unaspis yanonensis(Kuwana,1923)published by PeerJ(Liu etal.2020).In our study,we determine that the putative"P.citri and U.yanonensis"mitogenomes did not originate from Coccoidea but from parasitic wasps in the Chalcidoidea.These results are based on the genetic distances of the barcoding sequences of cytochrome c oxidase I(COI)and on molecular identifications performed against the Basic Local Alignment Search Tool(BLAST)in NCBI.
The genus Blepharicera Macquart,1843 is recorded from Xizang,China for the first time with the species B.xizangica sp.nov.which is described and illustrated as new to science.This new species is distinguished from congeners mainly by body color and male genitalia.A key to Chinese Blepharicera species is presented.
Five species in the genus Tetraleurodes Cockerell(Hemiptera:Aleyrodidae)known to occur in China were studied.Tetraleurodes thenmozhiae Jesudasan and David is recognized as a newly recorded species to China and is redescribed with morphological illustrations and photographs taken with a scanning electron microscope(SEM).Comments on the other four species,T.acaciae(Quaintance),T neemani Bink-Moenen,T.graminis Takahashi and T.oplismeni Takahashi are provided.An identification key to the puparia of Chinese Tetraleurodes species is given.Specimens are deposited in the Insect Collection of Zhejiang Agriculture&Forestry University,Hangzhou,China.
