Planthoppers (Delphacidae), leafhoppers (Cicadellidae) and froghoppers (Aphrophoridae) (Hemiptera: Auchenorrhyncha) caught during day and night sampling at a height of 200 m above ground at Cardington, Bedfordshire, UK, during eight summers (between 1999 and 2007) were consolidated with high-altitude catches made over England in the 1930s. Comparisons were made with other auchenorrhynchan trapp...

Malaise trap sampling of Hemiptera (Heteroptera; Auchenorrhyncha) was conducted at 500 m intervals along an elevational gradient from 200 m to 3,700 m on the east slope of Mount Wilhelm, Madang Province, Papua New Guinea. Hemiptera had a decrease in morphospecies richness and overall abundance with increasing elevation, however, the Heteroptera did not exhibit either pattern. A few species were...

A new monobasic subgenus, Macropsis (Spinoniacropsis) subgen. nov., of the subfamily Macropsinae (Hemiptera: Auchenorrhyncha: Cicadellidae) based on type species Macropsis flavovirens Kuoh, 1992 from Yunnan Province of China is proposed. The new subgenus can be distinguished by the unique character of the male pygofer with two spinelike processes on the caudal margin. Macropsis (S.)flavovirens ...

Abstract Acanalonia conica (Say, 1830), the first representative of Nearctic planthopper family Acanaloniidae (Hemiptera: Auchenorrhyncha: Fulgoroidea), introduced to Europe, is reported for time from multiple locations in Hungary. Diagnosis, detailed illustration male genitalia and notes on ecology are provided along with distributional records.

iranian species of the leafhopper genus neoaliturus distant, 1918 (n. alboflavovittatus (lindberg), n. decemocellatus (dlabola); n. dubiosus (matsumura), n. fenestratus (herrich-schäffer), n. guttulatus (kirschbaum), n. haematoceps (mulsant and rey), n. opacipennis (lethierry), n. pulcher (haupt); n. tenellus (baker)) are reviewed. detailed morphological descriptions and illustrations and a key...

Insect species in the Auchenorrhyncha suborder (Hemiptera) maintain ancient obligate symbioses with bacteria that provide essential amino acids (EAAs) deficient in their plant-sap diets. Molecular studies have revealed that two complementary symbiont lineages, "Candidatus Sulcia muelleri" and a betaproteobacterium ("Ca. Zinderia insecticola" in spittlebugs [Cercopoidea] and "Ca. Nasuia deltocep...

The order Hemiptera was formerly divided into two suborders, Heteroptera and Homoptera. The suborder Homoptera was also divided into two convenient groups, the Auchenorrhyncha and the Sternorrhyncha, the latter comprising the superfamilies Aphidoidea, Psylloidea, and Aleyrodoidea, plus the scale insects in the superfamily Coccoidea. Until about the mid-20th century, most workers on scale insect...

Four new species in two new genera of leafhoppers (Hemiptera, Auchenorrhyncha, Cicadellidae, Deltocephalinae) are described. All are associated with Xerophyta species (Velloziaceae, Pandanales), and are usually tended by ants. Observations and discussions of the ant associations are provided. The new leafhopper genera and species are: Xerophytavorus furcillatus gen.n & sp.n., from Malawi, and t...

The species Gonatopus vidanoi Olmi, 1994 and Haplogonatopus hernandezae 1984 (Hymenoptera: Dryinidae) are recorded for the first time from urban parks of Bogotá city (Colombia). In addition, is in Colombia. These new records contribute to a better knowledge diversity parasitoid wasps present Colombia, context their trophic role as natural enemies leafhoppers (Hemiptera: Auchenorrhyncha) recogni...
