The genus Anufrievia Dworakowska, 1970 is widely distributed in China, Korea, South Korea, Japan, Nepal, India, Thailand, Vietnam and Vietnam. This work reports on two new species of Anufrievia found at Bijie City and Shibing County, Guizhou Province, China.Two new species of the leafhopper genus Anufrievia Dworakowska, 1970 from Guizhou Province China are described and illustrated, i.e., A. crispata sp. nov. and A. confluensa sp. nov. A key to distinguish the Chinese species of the genus is given.

The number and classification of tribes in the leafhopper subfamily Typhlocybinae are not yet fully clear, and molecular data has recently been used to help resolve the problem. In this study, the mitochondrial genomes of Mitjaevia shibingensis Chen, Song & Webb, 2020 and M. dworakowskae Chen, Song & Webb, 2020 of the tribe Erythroneurini (Cicadellidae, Typhlocybinae) were sequenced. Most protein-coding genes (PCGs) start with ATN and end with TAA or TAG, and the AT content of these three codons were found differ from previous results that show that the first codon has the highest incidence. Two rRNA genes are highly conserved, and the AT content in 16S is higher than that of 12S. The nucleotide diversity and genetic distance among 13 PCGs of the four tribes from Typhlocybinae show that Empoascini nucleotide diversity is significantly less than in the other three tribes, and have the largest distance from the others, while Typhlocybini and Zyginellini have the smallest distance, indicating that the relationship between the two is the closest. The nad2, nad4, nad4L, and nad5 genes have greater nucleotide diversity, showing potential for use as the main markers for species identification. The phylogenetic analysis yielded a well-supported topology with most branches receiving maximum support and a few branches pertaining to relationships within Zyginellini and Typhlocybini receiving lower support. The species of these two tribes are intertwined, and it was impossible to resolve them into separate branches. In addition, the tribes Empoascini and Erythroneurini were recovered as monophyletic, and Alebrini was placed at the base of the tree as the most primitive. These results are broadly in line with other molecular phylogenetical studies which differ from traditional morphological classification.

Complete mitochondrial genome sequences facilitate species identification and analyses of phylogenetic relationships. However, the available data are limited to the diverse and widespread insect family Cicadellidae. This study analyzes and summarizes the complete mitochondrial genome structure characteristics of 11 leafhopper subfamilies and two newly sequenced Typhlocybinae species, Empoascanara wengangensis and E. gracilis. Moreover, using 13PCGs and rRNA data to analyze the nucleotide diversity, evolution rate, and the phylogenetic relationship between the subfamilies of 56 species, verifying the taxonomic status analysis of E. wengangensis and E. gracilis. The analysis results show that the genome structures of the subfamilies and the newly sequenced two species are very similar, and the size of the CR region is significantly related to the repeat unit. However, in the entire AT-skews and CG-skews, the AT-skews of other subfamilies are all positive, and CG-skews are negative, while Empoascini of Typhlocybinae and Ledrinae are the opposite. Furthermore, among 13PCGs, the AT-skews of 13 species are all negative while CG-skews are positive, which from Empoascini in Typhlocybinae, Idiocerinae, Cicadellinae, Ledrinae, and Evacanthinae. Phylogenetic analysis shows that ML and PB analysis produce almost consistent topologies between different data sets and models, and some relationships are highly supported and remain unchanged. Mileewinae is a monophyletic group and is a sister group with Typhlocybinae, and the sister group of Evacanthinae is Ledrinae + Cicadellinae. Phylogenetic analysis grouped the two newly sequenced species with other species of Typhlocybinae, which was separated from other subfamilies, and all Erythroneurini insects gathered together. However, E. gracilis grouped into a single group, not grouped with species of the same genus (Empoascanara). This result does not match the traditional classification, and other nuclear genes or transcriptome genes may be needed to verify the result. Nucleotide diversity analysis shows that nad4 and nad5 may be evaluated as potential DNA markers defining the Cicadellidae insect species.

Guizhou is regarded as one hotspot for China's Erythroneurini diversity, from where numerous rare new species have been, or are being, described.

Anointing and grooming behaviors of the adult of Singapora shinshana (Matsumura) (Erythroneurini), Empoascanara (Empoascanara) mai Dworakowska (Erythroneurini), Austroasca vittata (Lethierry) (Empoascini), and Limassolla diospyri Chou et Ma (Zyginellini) were recorded and analysed. Through observation and analysis of their anointing and grooming, we found that there is a preparation stage before anointing behavior in typhlocybines. Anointing and grooming are repeated several times and the numbers and interval times differ from species to species among the Typhlocybinae. Ultramorphological examination of brochosomes and the morphology of the brochosome field, metathoracic tibiae and the structures on the head, face, mesothorax and pygofer of E. mai were done using a scanning electron microscope. Brochosomes (IBS) on the cuticle of typhlocybine adults were spherical visible above these integument. Characteristics of anointing and grooming behavior, the provide evidence that the brochosome field may function as a storage site in preparation for the next grooming session.

The leafhopper species Tautoneura polymitusa Oh & Jung, 2016 (Hemiptera: Auchenorrhyncha: Cicadellidae: Typhlocybinae: Erythroneurini), described recently from Korea, is recorded from Hungary, representing the first known European occurrence of the species and also of the genus Tautoneura Anufriev, 1969. The species is illustrated, its diagnostic characters are discussed and compared with those of the closely related congeners. The occurrence of T. polymitusa in three isolated localities in Hungary and regular records in Budapest over a period of five years since 2012 indicate that stable populations exist in Hungary, the species is probably already established and it is locally abundant. It is apparently associated with elm trees (Ulmus spp.) and other members of the plant family Ulmaceae. Its further spread in Europe is expected.
