A new species of Oligosita Walker (Chalcidoidea: Trichogrammatidae), O. balcluthae Viggiani et Laudonia n. sp., is described as a parasitoid of the eggs of Balclutha brevis Lindberg (Homoptera: Cicadellidae) associated with crimson fountain grass, Pennisetum setaceum (Poaceae) in Italy. Morphological features and biology of the new species are discussed and illustrated. The 28S-D2 and ITS2 regi...

The Chinese mainland species of the leafhopper genus Nephotettix Matsumura (Hemiptera: Cicadellidae: Deltocephalinae: Chiasmini) (Nephotettix cincticeps (Uhler), Nephotettix malayanus Ishihara & Kawase, Nephotettix nigropictus (Stål), Nephotettix parvus Ishihara & Kawase rec. n., and Nephotettix virescens (Distant)) are reviewed. This genus is redescribed. Variation is described and illustrated...

Bambusananus cuihuashanensis sp. n. (Hemiptera: Cicadellidae: Deltocephalinae: Athysanini), a new bamboo-feeding leafhopper species, is described and illustrated from Shaanxi Province of China. Checklist, host plants and distribution for each species of Bambusananus is given along with a key to all known species.

Comparative assessments of Gonatocerus ashmeadi and the ‘new association’ parasitoid G. deleoni (Hymenoptera: Mymaridae) as biological control agents of Homalodisca vitripennis (Hemiptera: Cicadellidae) N.A. Irvin a & M.S. Hoddle a b a Department of Entomology, University of California, 900 University Ave, Riverside, CA, 92521, USA b Center for Invasive Species Research, University of Californi...

The two Chinese species of the leafhopper genus Exitianus Ball (Hemiptera: Cicadellidae: Deltocephalinae: Chiasmini) (Exitianus indicus (Distant) and Exitianus nanus (Distant)) are reviewed. Descriptions of the species and a key for their separation are provided. Exitianus fulvinervis Li & He is considered a junior synonym of Exitianus nanus syn. n.

Diramus, gen. nov. (Hemiptera: Cicadellidae: Evacanthinae), and three new species, Diramus khaokus sp. nov., Diramus nigromaculatus sp. nov. and Diramus uncatus sp. nov., are described from Thailand. The differences between the new genus and the closely related genus Bundera Distant is discussed.

Two leafhopper (Hemiptera Cicadellidae) hosts are reported for Gonatocerus (Gonatocerus) californicus Girault (Hymenoptera Mymaridae): Exitianus obscurinervis (Stal) and Spangbergiella vulnerata lacerdae Signoret. At El Manantial site in Tucumán Province, Argentina, G. californicus emerged from 7.1% and 90.5% of the parasitized sentinel eggs of the respective host on maize plants. Notes on the ...

Classical arthropod biological control programs lack a universally adopted, broadly utilitarian, and standardized risk assessment testing strategy for precisely estimating physiological and ecological host range of potential biological control agents. We implemented a rigorous host specificity testing protocol for estimating potential physiological and ecological risk to non-target species pose...

This paper treats all four known species of the genus Neurotettix Matsumura, 1914 (Hemiptera, Cicadellidae, Deltocephalinae), including one new species: Neurotettix truncatussp. n. from China. A key is given to distinguish all species of the genus, and illustrations of genitalia are provided.
