Description

Medium-sized, cylindrical leafhoppers (Figs 2–14). Head (Figs 2–14) broader than pronotum; ocelli visible in dorsal aspect; frontoclypeus expanded with prominent transverse muscle scars; lateral frontal sutures extended ventromesad of ocelli; antennal ledges well developed; antennae subequal to or longer than width of head; anteclypeus convex and tapered from base to apex; lorum short, narrow, well separated from genal margin, partly bordering frontoclypeus; gena slightly emarginate below eyes, exposing proepisternum; rostrum tapered, surpassing front trochanters.
Pronotum (Figs 2–5, 7–11, 13, 14) greatly enlarged, strongly convex, distinctly punctate, weakly produced anterad, extended posterad to scutellar suture. Forewings (Figs 15, 17, 19) macropterous with venation distinct and opaque sclerotization, if present, limited to basal third; vein R with two (R1 not visible as separate vein) or three branches; crossvein s present (outer anteapical cell closed); inner apical cell elongate, parallel-sided, extended to wing apex. Hind wings (Figs 16, 18, 20) with venation complete; submarginal vein well separated from wing margin. Forelegs with femur with AM1 weakly developed or absent, intercalary row and distal half of AV well differentiated, each with several setae arranged in single row; tibia cylindrical, AD and PD undifferentiated. Hind legs with femur with macrosetal formula 2+0; tibia with macrosetae of dorsal rows reduced in size and number; tarsomere I without dorsoapical pair of macrosetae; pecten with 2 platellae.
Male genital capsule (Figs 21–24, 29–42) with valve articulated or fused laterally to pygofer; pygofer without distinct membranous clefts near base; segment X very large, well sclerotized, with or without processes; subgenital plates digitiform, broadest at base, usually with numerous fine setae dorsally but only rarely with well differentiated macrosetae; connective Y-shaped; style sigmoid; with or without sclerotized dorsal connective or other sclerotized processes between anal tube and aedeagus usually present.
Female ovipositor (Figs 26, 27) elongate, variable in shape and dentition.

Distribution

Afrotropical and Oriental.

Notes

With the exception of the proconiine sharpshooter genus Tretogonia Melichar, 1926 and the recently described dikraneurine (Typhlocybinae) genus Sweta Viraktamath & Dietrich 2011, Signoretiinae are the only leafhoppers with fully developed wings that have the pronotum extended to the scutellar suture. Viraktamath and Dietrich (2011)[1] discussed several characters supporting the placement of Sweta in Typhlocybinae rather than Signoretiinae. Interestingly all these leafhoppers have the long pronotum distinctly punctate.
Nothing is known about the ecology or feeding behavior of Signoretiinae, although the strongly convex or inflated face suggests that they preferably feed on xylem sap.
