Recorded hosts
Wheat (Sogatella vibix), Rice (Sogatella furcifera), Maize (Sogatella kolophon, Sogatella vibix). Asche and Wilson (1990) note that the genus is associated with grasses, but the level of specialization on hosts is unclear.
Economic importance
Sogatella furcifera is the white-backed planthopper (WBPH), and important pest of rice in the Old World. Sogatella furcifera, and other Sogatella are known for migratory habits.
Sogatella furcifera is known to vector Pangola stunt virus (PSV), and Southern Rice Black Streak Dwarf Virus (SRBSDV). Sogatella kolophon is known to vector Brazilian wheat spike disease (BWSV), Digitaria striate virus (DSV), and Maize sterile stunt virus (MSSV). Sogatella vibex is known to vector Finger millet mosaic virus (FMMV), Maize rough dwarf virus (MRDV), and Maize sterile stunt virus (MSSV).
Recognition
All species tend to be straw to brown color with a conspicuous pale stripe down the midline of the dorsum. Recognition of species, particularly when it is unclear whether the species is endemic or potentially invasive, can be challenging. Color can be both helpful and misleading, particularly since color intensity can vary quite a bit between males and females of the same species and between individuals from different localities. Some species can be very common and can be collected in considerable numbers. Individuals can travel great distances and may be found well outside their usual range.
Sogatella kolophon is easily the most abundant New World species of Sogatella
The genus Sogatella is quite similar to Tagosodes (and Sogatellana and to a lesser degree Matutinus). Males are much preferred for identification. Females can be difficult to distinguish to genus, and can only be tentatively assigned to species. These genera can best be separated by the shape of the genital diaphragm of the male - which is broadly "u" shaped in Sogatella versus a rectangular protrusion or raise T-shaped area in Tagosodes.

Note the bifurcate apex of the parameres and the gena ('cheeks') of the face of the male is straw-colored (instead of dark in S. molina).
Sogatella molina






Compared to S. kolophon, notice the dark genae ('cheeks' of the face), and the slightly different shape of the parameres.
Sogatella furcifera - Does not occur in the New World. Reports of this species in the New World have been through misidentification (See Asche and Wilson 1990). (Although I had heard that a population was exterminated in Florida).







Notice the dark face and the different shape of the parameres.

Sogatella vibix - Does not occur in the New World





Notice the pale face and dark genae ('cheeks') compared to S. furcifera and S. kolophon, and the differently shaped paramere compared to S. furcifera.
Molecular resources
A considerable variety of molecular resources are available on Genbank for Sogatella furcifera here. BOLD indicates barcodes are available for Sogatella furcivera and Sogatella vibix (here). Sogatella molina and S. furcifera were sequenced for 18S, 28S, CO1, WG in Urban et al. (2010).
