Two new bamboo-feeding species of the cixiid planthopper genus Neocarpia Tsaur & Hsu, 2003 (Hemiptera: Fulgoromorpha: Cixiidae: Eucarpiini), N. bidentata sp. nov. (Guizhou: Xishui) and N. hamata sp. nov. (Guizhou, Yanhe), from southwest China, are described and illustrated. The generic characteristics are redefined. A key and a checklist to the known species of this genus in the world are provi...

Six new species of the planthopper genus Usana, U. aspergilliformis sp. nov., U. concava sp. nov., U. congjiangensis sp. nov., U. fissura sp. nov., U. oblongincisa sp. nov. and U. unispina sp. nov. are described and illustrated from China. A checklist, a key to all species of the genus and illustrations of U. lineolalis Distant, 1906 are also given.

This paper deals with the genus Trachypeplus from China. Nine species of Trachypeplus are treated in this paper, of which three species, namely Trachypeplus depressus sp. nov., Trachypeplus jingae sp. nov., and Trachypeplus parafulgoris sp. nov., are described as new. These nine species are photographed and keyed.

The two leafhopper species in the genus Parazyginella Chou & Zhang from China are reviewed and illustrated including one new species, Parazyginella tianisp. n. whichis described. A key to separate males of the two species is provided.

The genus Naevus Knight, 1970 is recorded from the mountains of southwestern Saudi Arabia, the first record from the Arabian Peninsula. A new species, Naevus hathali El-Sonbati & Wilson sp. n. is described here, which appears to have an asymmetric aedeagus. An illustrated key to Naevus species is presented to facilitate identification.

Xynotingis hoytana Drake, 1948 and Zeiratingis hainanensis sp. nov. are recorded from China (Hainan Island). Species of both genera are very rarely collected. This represents the first record of both genera in this country. The new species is described. Illustrations of the involved species are provided as well as a key to the species of the genus Zeiratingis.

Searching for morphometric differences between sexes in immature forms, the development of genital plates in the exuviae of Triatoma pallidipennis Stål 1872 nymphs was studied. Differences were found in the form and size of the 9th genital urosternite, it is larger and wider in males as compared to females. This difference is reported in several South American Triatoma species. From our results...

The leafhopper fauna of northwestern Iran: Azarbaijan-e-Sharghi, Azarbaijan-e-Gharbi and Ardabil provinces is listed from previously published records and from our current work. Sixty-nine species are included with four species (Mogangellastraminea Dlabola, 1957, Doraturastylata (Boheman, 1847), Macrostelessordidipennis (Stål, 1858) and Psammotettixseriphidii Emeljanov, 1962) listed as new for ...

We report and describe the first species of Atheroides Haliday presumed to be native to North America, collected at the Valles Caldera National Preserve, New Mexico, USA. We hypothesize its placement among the Siphini based on morphological, phylogenetic analysis and extend the distribution of the genus to the Holoarctic. We expand the key of the known Atheroides to include the new species and ...

Species of the extinct family Dysmorphoptilidae with distinctly punctate and emarginate tegmina are one of the most characteristic elements of the hemipteran fauna of the three Queensland Triassic fossil insect-bearing formations-the Middle Triassic (Anisian) Gayndah Formation at Gayndah, the Late Triassic (Norian) Mount Crosby Formation at Mount Crosby, and the Late Triassic (Norian) Blackston...
