To explore the mitogenome characteristics and shed light on the phylogenetic relationships and molecular evolution of Drabescini species, we sequenced and analyzed the complete mitochondrial genome of two species including Drabescus ineffectus and Roxasellana stellata. The complete mitogenomes of D. ineffectus and R. stellata are circular, closed and double-stranded molecules with a total length of 15744 bp and 15361 bp, respectively. These two newly sequenced mitogenomes contain the typical 37 genes. Most protein-coding genes (PCGs) began with the start codon ATN and terminated with the terminal codon TAA or TAG, with an exception of a special initiation codon of ND5, which started with TTG, and an incomplete stop codon T-- was found in the Cytb, COX2, ND1 and ND4. All tRNAs could be folded into the canonical cloverleaf secondary structure except for the trnS1, which lacks the DHU arm and is replaced by a simple loop. The multiple tandem repeat units were found in A + T-control region. The sliding window, Ka/Ks and genetic distance analyses indicated that the ATP8 presents a high variability and fast evolutionary rate compared to other PCGs. Phylogenetic analyses based on three different datasets (PCG123, PCG12R and AA) using both Bayesian inference (BI) and maximum likelihood (ML) methods showed strong support for the monophyly of Drabescini.

The Oriental leafhopper genus Parabolopona Matsumura (Cicadellidae: Deltocephalinae: Drabescini: Paraboloponina) is reviewed with description of a new species, Parabolopona yunnanensis sp. nov., from China. An updated checklist with distributions and a key to males of this genus are also provided.

Two new species from China, Drabescus macrocladus sp. nov. and Drabescus mucronatus sp. nov., are described and figured. An updated checklist with distributions and key to males of the species in this genus from China is given. The type specimens of these two new species are deposited in the Entomological Museum, Northwest A&F University, Yangling, Shaanxi, China (NWAFU) and in Sun Yat-Sen University (Zhongshan University, ZSU), Guangzhou, Guangdong, China.

The leafhopper genus Nirvanguina Zhang & Webb (Cicadellidae: Deltocephalinae: Drabescini: Paraboloponina) is reviewed, including description of a new species, Nirvanguina bifurcatus Xu & Zhang sp. nov., from China. An updated checklist along with distribution and a key to males of this genus are also provided. Type specimens of this new species are deposited in the Entomological Museum, Northwest A&F University, Yangling, Shaanxi, China (NWAFU).

A new genus of Ianeirina (Cicadellidae: Deltocephalinae: Selenocephalini), Gyrosus gen. nov. including the new species Gyrosus deltodontus sp. nov. as the type species, is described and illustrated from South Africa. Habitus photographs of adult leafhoppers and the genitalia of this new species are provided. Type specimens of this new species are deposited in the Iziko South African Museum, Cape Town, South Africa (ISAM).

The African leafhopper genus Angolaia Linnavuori & Al-Ne'amy, 1983 (Cicadellidae: Deltocephalinae: Selenocephalini: Selenocephalina) is reviewed, including description of the new species, Angolaia picea sp. nov., from Zambia. An updated checklist with distribution and a key to males in this genus are also provided. Type specimens of this new species are deposited in the Illinois Natural History Survey, University of Illinois, Champaign, Illinois, USA (INHS).
