Introduction
This genus was reviewed by Asche and Wilson (1990) and currently contains 15 species distributed in most regions of the world. Only three species are recorded in Australia and all three are also widely distributed elsewhere in the world. They were almost certainly introduced to Australia with cereal plants. Two of the species are known vectors of plant diseases while the third, S. furcifera, causes direct feeding damage to rice and is one of the world's worst planthopper pests of rice (Wilson & Claridge 1991).

Diagnosis
Small and slender delphacids. Macropterous males about 2.5–3.5 mm, macropterous females about 3.0–4.0 mm. Vertex rounded onto frons, anterior cell of vertex long, reaching to apex of vertex or bent towards frons. Colouration: males with a whitish longitudinal stripe across vertex and the middle portion of pro- and mesonotum; lateral portions of pro- and mesonotum brown or black. Females distinctly lighter than males, yellow to orange, stramineous or light brown.
Sogatella can be distinguished from other externally similar genera by a combination of the following three characters of the male genitalia. 1. The dorsal margin of the diaphragm in the middle possesses two cone-shaped processes which are medially connected by a dorsally slightly concave tuberosity, altogether forming a broad U-shaped structure. 2. The aedeagus is moderately long, slightly sinuate, after its basal third it is bent dorsad, with the tip curved ventrad, slightly compressed and twisted tapering to the apex. Two rows of small teeth are present ascending from the ventrodorsal third on both sides to the dorsal third. The phallotreme is situated subapically on the left side. 3. The parameres are diverging, in most of the species tapering to apex and distally bifurcated. (Asche & Wilson 1990)
