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.

Simple Summary Typhlocybinae is the smallest sized and most evolved leafhopper, body length 2–4 mm, forewing with four apical cells but lacking closed preapical cells. It comprises over 6000 species (Dietrich, 2013) distributed worldwide, making it the second largest group of Cicadellidae. Previous phylogenetic analyses in this subfamily were mainly based on morphological characters and were restricted to several gene fragments. To provide further insight into the relationships of its included tribes, complete mitogenomes of two Alebrini species (Shaddai acuminatus, Sobrala sp.), two Dikraneurini species (Dikraneura (Dikraneura) zlata, Robusta emeiensis), two Empoascini species (Alebroides salici, Empoasca serrata), two Erythroneurini species (Elbelus tripunctatus, Kaukania anser), two Typhlocybini species (Eupteryx (Eupteryx) adspersa, Eurhadina jarrary), and one Zyginellini species (Yangisunda tiani) are newly sequenced and comparatively analyzed. The mitogenomes comprise the typical set of 37 mitochondrial genes and a large non-coding region (A+T-rich region). The acceptor arm of trnR is the most inconstant among all the tRNAs, due to the acceptor arm comprising unpaired bases. Phylogenetic analyses using Bayesian inference and maximum likelihood methods produced a well-resolved framework of Typhlocybinae, showed the monophyly of Typhlocybinae and its inner tribes, except for Typhlocybini and Zyginellini combined. These results provide the valuable data toward the future study of the phylogenetic relationships in this subfamily. Abstract To explore the characteristics of mitogenomes and discuss the phylogenetic relationships and molecular evolution of the six tribes within Typhlocybinae, 11 complete mitogenomes are newly sequenced and comparatively analyzed. In all of these complete mitogenomes, the number and order of the genes are highly conserved in overall organization. The PCGs initiate with ATN/TTG/GTG and terminate with TAA/TAG/T. Almost all tRNAs are folded into the typical clover-leaf secondary structure. The control region is always variable in length and in numbers of multiple tandem repeat units. The atp8 and nad2 exhibits the highest evolution rate among all the PCGs. Phylogenetic analyses based on whole mitogenome sequences, with three different datasets, using both maximum likelihood and Bayesian methods, indicate the monophyly of Typhlocybinae and its inner tribes, respectively, except for Typhlocybini and Zyginellini that are paraphyletic. Finally, we confirm that Erythroneurini is a subtribe of Dikraneurini.

An unusually dark typhlocybine leafhopper (Cicadellidae, Typhlocybinae, Erythroneurini) from Guizhou Province, China, is described as a new genus and species, Shibingagen. nov., and S. nigrasp. nov. Detailed morphological descriptions and illustrations of the new species are provided.

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.

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.

Separate keys are provided for identification of males from North and South America, all known species are illustrated, and data on their distributions are summarized. Phylogenetic analysis of 40 morphological characters of the 71 species for which males are known yielded a reasonably well resolved estimate of relationships among the included species, but branch support was low overall.

Species of Erythroneurini (Cicadellidae: Typhlocybinae) currently placed in the genus Zygina and found in Australia, New Zealand and some neighbouring islands are transferred to the new genus Anzygina, type species Erythroneura sidnica Kirkaldy, following comparison with the type species of the genus: Typhlocyba nivea Mulsant and Rey. New combinations are Anzygina sidnica (Kirkaldy), Anzygina honiloa (Kirkaldy), Anzygina melanogaster (Kirkaldy) and Anzygina sativae (Evans) from Australia, Anzygina toetoe (Cumber), Anzygina agni (Knight), Anzygina dumbletoni (Ghauri) and Anzygina ramsayi (Knight) from New Zealand, Anzygina zealandica (Myers) from Australia and New Zealand, Anzygina jowettae (Knight) from Norfolk Island and Anzygina medioborealis (Ghauri) from Papua New Guinea. Lectotypes are designated for Erythroneura honiloa Kirkaldy and E. sidnica Kirkaldy. Anzygina billi sp.n. is described from SE Qld, and Anzygina barrattae sp.n. is described from the South Island of New Zealand. A. agni is a new record for Australia and is presumed to be Australian in origin. A. dumbletoni has a distribution which suggests that it also is introduced to New Zealand although its origins are not known. A. ramsayi, A. barrattae and A. toetoe, all of which appear to be New Zealand endemics, show affinity with each other based on aedeagal structure. A key to these species, based on males, is provided. The lack of male syntypes for Erythroneura honiala Kirkaldy and Erythroneura lubra Kirkaldy precludes establishment of their identities relative to other species of the genus, and both names are regarded as having nomen dubium status. Australian species not transferred to Anzygina are Zygina evansi (Ross) and Zygina ipoloa (Kirkaldy), both of which belong elsewhere.

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.
