RESUMEN
The genus Batracomorphus Lewis is the third largest leafhopper genus in the world, with its greatest diversity in the Oriental region. Here, nine species of Batracomorphus, including one new species, are recorded from Shaanxi Province, China, for the first time: B. allionii (Turton), B. clavatus Cai and Shen, B. fletcheri Hu and Dai sp. nov., B. geminatus (Li and Wang), B. juno Knight, B. lateprocessus Li and Wang, B. lunatus Cai and He, B. subfuscus (Li and Wang) and B. pandarus Knight. Among them, B. juno Knight is recorded from China for the first time. One new synonym is revealed: B.nigromarginattus Cai and Shen, 1999 is a junior synonym of B. subfuscus (Li and Wang, 1993). All taxa are described, and photographs of male genitalia are given based on observations of specimens from Qinling Mountain in Shaanxi of China. A key to the species found in Qinling Mountain of Shaanxi is also provided.
RESUMEN
Three new Brazilian species of Polana (Varpulana) are described and illustrated, based on males and females: P. (V.) agualimpa sp. nov., from Distrito Federal; P. (V.) feitosai sp. nov., from Piauí and P. (V.) recurva sp. nov. from Paraná. An updated key to males of P. (Varpulana) is presented, the diagnosis of the subgenus is revised and a new state record is presented to P. (V.) pandara. Additionally, morphological differences found in the dorsal sculpturing of the first valvula between the species of Polana are reported.

Two new species of Bertawolia and one of Momoria are described and illustrated from Brazil: Bertawolia grazielia sp. nov. from Paraná and Santa Catarina; B. lata sp. nov. from Paraná and Momoria albohabena sp. nov. from Paraná and Minas Gerais. The female genitalia of Bertawolia and Momoria species are described and illustrated by the first time. In addition, host plants for B. grazielia sp. nov. and M. albohabena sp. nov. are recorded and a key to species of Bertawolia is given.

For elucidating phylogenetic relationships among members of the family Cicadellidae, mitogenomes of six members of the subfamily Iassinae, including Batracomorphus lateprocessus, Iassus dorsalis, Krisna concava, Krisna rufimarginata, Gessius rufidorsus, and Trocnadella arisana, were sequenced. The mitogenomes are 14,724-15,356-bp long. Moreover, typical 37 genes in mitogenomes were identified; arrangement of these genes in the studied species was consistent with that in the inferred ancestral insects, except for tRNA genes, with a simple switch between the positions of trnI and trnQ in Trocnadella arisana. Most protein-coding genes in the Iassinae mitogenomes showed typical ATN start codons (ATA/ATT/ATC/ATG) and TAR (TAA/TAG) or an incomplete stop codon T--; ATP8 of all sequenced species showed the start codon TTG. The secondary structures of 16S rRNA and 12S rRNA were predicted. 16S rRNA comprised 6 domains with 43 helices, and 12S rRNA comprised 3 domains with 25 helices. All subfamilies, except Cicadellinae and Evacanthinae, were recovered as monophyletic. As reported previously, treehoppers originated from paraphyletic Cicadellidae. Iassinae and Coelidiinae, Megophthalminae and treehoppers, and Cicadellinae and Evacanthinae were sister groups with high nodal support.

The genus Acusana is recorded from the Brazilian fauna for the first time, with the description of four new species: Acusana adunca sp. nov. and Acusana spina sp. nov. from Mato Grosso, Central-Western Brazil and Acusana dilatata sp. nov. and Acusana longa sp. nov. from Maranhão, Northeast Brazil. Detailed description and illustrations of male and female are provided, as well a revised diagnosis for the genus. The female genitalia of Acusana species is described and illustrated by the first time. A new record of Acusana paga DeLong Freytag, 1966 is added from Costa Rica.

Two new monotypic genera of Gyponini from South America are proposed, described and illustrated. Caetana gen. nov., from Brazil and Ecuador, differs from other genera of the tribe by the scutellum strongly inflated; forewing expanded apically and hind wing with long r-m and m-cu. Insolitana gen. nov., from Peru, differs from other genera by the presence of a pair of longitudinal carinae on crown; crown, noto, and clavus punctuated; male sternite VIII (= pregenital sternite) fully covering the subgenital plates; and pygofer with internal dorsoapical process.
