Description:
The Oriental leafhopper genus Toba Schmidt is reviewed and placed in the subfamily Stegelytrinae Baker. Its type species, T. fasciculata Schmidt, and a new species T. sandakanensis Wei & Webb, are described with details of the male and female genitalia given for the first time. A related new genus and species, Paratoba longa Wei & Webb, gen. n. and sp. n., are described. The subfamily status and the morphological similarities between these two genera and other taxa are discussed.

Description:
We review the cicada genus Auritibicen Lee, 2015 based on the description of ten new species: A. aethus sp. n., A. daoxianensis sp. n., A. pallidus sp. n., A. rotundus sp. n., A. curvatus sp. n., A. purus sp. n., A. parvus sp. n., A. gracilis sp. n., A. septatus sp. n. and A. lijiangensis sp. n. Auritibicen shikokuanus (Kato, 1959) is confirmed to be a synonym of Auritibicen kyushyuensis (Kato, 1926). Diagnoses and descriptions, along with illustrations of the structure of male genitalia, are provided for all Auritibicen species. The systematics of Auritibicen is elucidated using both morphological and molecular characterization. Thirty-five morphological characters of the 24 species of Auritibicen and one outgroup taxon, Chremistica ochracea (Walker, 1850), were scored. Morphological phylogenetic analyses reveal the relationships among related species of Auritibicen, which are supported by a number of morphological characters. The mitochondrial gene fragments of Cytochrome Oxidase I (COI) of 11 species of Auritibicen and two outgroup Lyristes species were analyzed and yielded identical robust phylogenetic trees. The phylogram based on a Bayesian analysis of both morphological and molecular data is similar to the ML/BI topologies based only on the molecular data. The molecular phylogenetic analysis indicates that species of Auritibicen are structured phylogeographically, with related species clustered into three lineages. The divergence time estimated based on molecular data indicates that the divergence of Auritibicen from Lyristes occurred during the Miocene, and the most recent common ancestor (tMRCA) of Auritibicen evolved during the Pliocene. However, the time when the main divergence events of species of Auritibicen occurred was the Pleistocene. From the combination of the phylogeny and updated geographical distributions, we infer that the center of distribution of Auritibicen could be Southwest China (e.g., Sichuan and Yunnan Provinces), from where species of this genus spreaded northeastwards to Shaanxi, Hubei and other provinces along the Qinling and Daba Mountains, then further northeastwards to Hebei Province in China and also to Far East Russia, the Korean Penisula, and Japan.
