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.

The leafhopper genus Anufrievia was established by Dworakowska with A. rolikae Dworakowska as its type species. They are widely distributed in China, North Korea, South Korea, Japan, Nepal, India, Indonesia, Thailand and Vietnam. Two new species, A. ventricosa sp. nov. and A. unianxialis sp. nov., found in the karst area of Guanling and Shibing City, Guizhou Province, China are described and illustrated. The key to the identification of the specie of this genus is given.

Three new species of the leafhopper genus MitjaeviaDworakowska 1970, M. bijiensissp. nov., M. solitariasp. nov., and M. salaxiasp. nov., are described from the Karst region of Southwest China. Specimens studied were taken by sweep net. Morphological descriptions, depictions of habitus and illustrations of male terminalia are provided. A key and checklist to known species occurring in China are given.

The leafhopper genus Empoascanara Distant, 1918 encompasses 81 species, most of which are distributed in Afrotropical, Oriental and Australian Realm. The leafhopper genus Kapsa Dworakowska, 1972 encompasses 23 species, mainly known from the Oriental and Australian Realms. Two new species of the leafhopper tribe Erythroneurini from Guizhou Province, China, Empoascanara dichotomus sp. nov. and Kapsa sinuose sp. nov. are described and illustrated. Identification keys to the males of the genera Empoascanara and Kapsa in China are proposed.

General characteristics of Gladkara Dworakowska and a checklist to all the known species of this genus are provided. A new species Gladkara klongensis Song & Dietrich, sp. n. from Thailand is added.

A new genus of the leafhopper tribe Erythroneurini (Cicadellidae, Typhlocybinae) from Thailand, Undulivenagen. n., and a new species Undulivenathaiensissp. n., are described and illustrated. The new genus exhibits a unique feature of the forewing venation with CuA vein strongly sinuate.

Seriana menglaensis sp. n. (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini) is described and illustrated from Southwest China. S. equata (Singh, 1969) is recorded for the first time from China.
