Pseudomaiestas gen. nov. with Pseudomaiestas dietrichi sp. nov. (type species, China: Yunnan Prov.), and Maiestas anhuiensis sp. nov. (China: Anhui Prov.) are described and illustrated. A checklist to the known genera and species of Deltocephalini from China is given together with a generic key. The tribe now holds 14 genera and 59 species in total from China. The genera Alobaldia Emeljanov, Amblysellus Sleesman, Ctenurella Vilbaste, Graminella DeLong, Matsumuratettix Metcalf, Peitouellus Vilbaste, Polyamia DeLong, Recilia Edwards, Wyushinamia Zhang & Duan, and Pseudomaiestas Xu, Shah & Duan gen. nov. contain 1 species. Similarly, Yuanamia Zhang & Duan includes 2 species, Paramesodes Ishihara contains 6 species, Deltocephalus Burmeister has 7 species, and Maiestas Distant is recorded with 34 species respectively. A separate key for the Chinese Maiestas species is also given.

A new leafhopper species Stirellus pakistanicus Shah & Duan sp. n. is described from Attock region of the Punjab province of Pakistan. Habitus photos and illustrations of male genitalia of the new species are provided. An updated checklist and a distribution map of the known species of Stirellus from Pakistan are also given.

The leafhopper genus Grammacephalus Haupt is revised with the description and illustrations of a new species Grammacephalus punjabensis Shah & Duan sp. n. from Pakistan. A checklist of the species of Grammacephalus and key to distinguish known species in the genus are also given in the present study.

Polyamia ( Polyamia ) choromorica sp. n., representing the first record of the genus Polyamia DeLong from South America, is described and illustrated. Previously described species of Polyamia DeLong appear to be restricted to North America. Color illustrations of Polyamia ( Copolyamia ) caperata (Ball), Polyamia ( Copolyamia ) similaris DeLong & Davidson and Polyamia ( Polyamia ) weedi Van Duzee are also provided for comparison. A species checklist and distribution summary for the genus is provided. Notes on other South American species of Deltocephalini with supernumerary forewing crossveins are also provided.

Morphological characters previously used to define the subgenus Amplicephalus ( Nanctasus ) Linnavuori and its status are discussed. Two new species are described and illustrated, and tentatively placed in subgenus A . ( Nanctasus ) Linnavuori: A . ( N .) anayensis sp. n. and A . ( N .) paralbivenosus sp. n. A checklist and a key to species of the subgenus are provided.

The leafhopper tribe Goniagnathini (Cicadellidae: Deltocephalinae) is reviewed from China. Seven species are recognised and a key provided for the six species for which males are known. One new species, Goniagnathus cornutus sp. n., is described and Megalopsius tamaricius Cai, is transferred to Tamaricades, comb. nov.

The Old World leafhopper genus Changwhania Kwon is reviewed and three of its four species are illustrated and male genital characters are provided. One new species from China, Changwhania digitata Zhang and Duan, is described. A key to species is also provided.

The grassland leafhopper subgenus Leofa (Prasutagus) is reviewed. Five species are dealt with in this paper, including two new species from China: Leofa (Prasutagus) forcipatus Duan & Zhang sp. nov. and Leofa (Prasutagus) yangae Duan & Zhang sp. nov., and a key to species is provided.

The South American leafhopper genus Cortona is moved from Macrostelini to Deltocephalini and is reviewed. Its type species and four new species, C. catanachae sp. n., C. concordica sp. n., C. otamendiensis sp. n., and C. silvai sp. n., are illustrated and described from Argentina. A checklist and a key to species are provided.

Miradeltaphus Dash & Viraktamath and Yuanamia Zhang & Duan are revised, one new species M . sanogae sp. n. is described and Parayuanamia Xing & Li is considered a junior synonym of Yuanamia Zhang & Duan syn. n. Both genera are newly recorded from Thailand. A revised key to the Palearctic and Oriental genera of Deltocephalini is provided.

Matsumura (1914) established Epitettix with the type species E. hiroglyphicus Matsumura, 1914 from Taiwan. Metcalf (1952) proposed the new name Matsumuratettix for Epitettix Matsumura, which was preoccupied by Epitettix Hancock, 1907. Dash & Viraktamath (1995) synonymised Pruthiorosius Ghauri with Matsumuratettix Metcalf. Currently, Matsumuratettix comprises a single species, M. hiroglyphicus (Matsumura, 1914). The genus is easily distinguished from other Old World Deltocephalini by the aedeagal shaft being strongly laterally compressed over the distal two-thirds and with asymmetrical distal spines. In this paper, a new species is described from Thailand and a key to distinguish the two known species is provided.

The Chinese mainland species of the leafhopper genus Nephotettix Matsumura (Hemiptera: Cicadellidae: Deltocephalinae: Chiasmini) (Nephotettix cincticeps (Uhler), Nephotettix malayanus Ishihara & Kawase, Nephotettix nigropictus (Stal), Nephotettix parvus Ishihara & Kawase rec. n., and Nephotettix virescens (Distant)) are reviewed. This genus is redescribed. Variation is described and illustrated. Keys for their separation are provided together with a worldwide checklist.

New leafhopper taxa in the deltocephaline tribe Scaphytopiini Oman are described: Xenovarta lui sp. n., and a new genus and species Aparaphysis lushuiiensis, gen. n., sp. n. from China. Detailed morphological descriptions and illustrations of the new genus and species are given. A checklist to genera of Scaphytopiini is provided.

Chinese species of Gurawa Distant (tribe Chiasmini) are reviewed and a new species, Gurawa truncata sp. nov., is described and illustrated. The related genus Chiasmus Mulsant & Rey is reported from China for the first time and descriptions and illustrations are provided for the genus and one undetermined species. Checklists to species of both genera are provided.
