Distribution Map
(simplified continental distribution)
Geographical Distribution:
Asia, Europe

Recorded Distribution(s):
Widely distributed in the Palaearctic to Japan (and Russian Maritime Territory). Appears also to be found at higher altitudes in tropical Asia (e.g. Northern Philippines, North Sumatra) where it may be found on upland rice.

L. striatellus is vector of black-streaked dwarf and stripe virus diseases of rice. In the Palaearctic region it is the vector of rough dwarf virus of maize (e.g. Harpaz, 1972). It is an important rice pest in Japan and southern Europe.

Species Description

Length:
. Male 3.4-3.6 mm, female 3.6-3.8 mm.

Colour:
The body of adult L. striatellus is black to dark-brown, and coloration varies with season. The wings are hyaline. The mesonotum is black to dark-brown, as is the pterostigma on the fore wings, and the areas between the carinae of the frons are deep black. These colours vary with general body coloration; the distinctive colour of the areas between the carinae of the frons is the most stable of the three and is diagnostic. Dark suffusion on the apical part of the fore wings, which occurs in certain delphacids, is absent.

Species Diagnosis

The shiny black mesonotum of the male, the pterostigma of the forewing and the male genitalia are diagnostic for the species. Male genitalia: The form of the aedeagus and the parameres are unlike any other delphacid found on rice. Short, sharp anal tube appendages, and the shape of the parameres and the diaphragm, are diagnostic.
