A new delphacid genus and species from Argentina, Lepidelphax pistiae Remes Lenicov, gen. et sp. nov.(Hemiptera: Fulgoromorpha: Delphacidae: Delphacini), is described and illustrated, and biological, distribution and experimental host range data are provided. Males of the new genus are easily distinguished from all other Neotropical Delphacini by being pale cream to white in color with a distin...

The mutualistic interspecific relationships of trophobiosis between trophobiont planthoppers (Hemiptera, Fulgoromorpha) providing food to the host called xenobiont, are reviewed. degree these symbionts varies from occasional or short time duration (a few hours a days) longer ones, with trophobionts left free escape (optobiotic type) by maintained enclosed in nests ant shelters (cryptobiotic typ...

Ninety percent of the Cixiidae Macaronesian archipelagos are endemic. Each archipelago has its own endemics reaching a total 31 taxa. The Madeira comprises five species: Cixius madeirensis China, 1938, C. verticalis Noualhier, 1897, chaoensis Hyalesthes madeires Remane & Hoch, 1986 and H. portonoves 1986. Good knowledge concerning taxonomy, habitat information distribution essential for...

The external morphology of the heads of adult male and female Cixiopsis punctatus (Matsumura) (Hemiptera: Fulgoromorpha: Tropiduchidae) was studied using scanning electron microscopy. Eleven types of sensilla or sensory organs were identified: trichoid sensilla on the pedicel, scape, maxillae, and labium; campaniform sensilla on the antennal pedicel, antennal scape, maxillae, and labium; plate ...
