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...

Iran is known as the most complex and varied country in southwest Asia, in terms of geography, vegetation, climate and consequently biological diversity. The rather high number of recorded endemic species of Fulgoromorpha in Iran indicates a high potential for speciation in some areas. In this study, in order to identify the endemic zones for Fulgoromorpha of Iran, three main biogeographic regi...

Ricania speculum (Walker, 1851) (Hemiptera: Fulgoromorpha: Ricaniidae) is reported for the first time in Europe. Both nymphs and adults were observed from 2009 in several municipalities of Liguria (Italy). Since the species is extremely polyphagous and is a real pest for several crops in tropical and subtropical areas, the presence of this alien insect is noteworthy, representing a new possible...

Three new species of the genus Exphora Signoret, 1860 (Hemiptera, Fulgoromorpha: Tropiduchidae) are described from Madagascar: E. constanti sp. n., E. stroinskii sp. n. and E. ambatolaonaensis sp. n. The male genitalia are described for the first time in this genus. The male genitalia, head and fore wing of the new species are illustrated with photos of habitus provided. Key to the known specie...

A new species of the planthopper genus Longtania Ding (Hemiptera: Fulgoromorpha: Delphacidae), L. arcuata n. sp. (central southern China: Hubei) is described and illustrated. A revised diagnosis of Longtania and a key to known species is provided. The genus is tentatively placed in the subtribe Delphacina. The genus Platytibia is reviewed and is assigned to the subtribe Numatina sensu Emeljanov...
