Description.

Dorsal coloration pale yellow to white ( Figs 8-14 ; except Signoretia greeni Distant, 1908). Head ( Figs 8 - 17 ) with crown bearing prominent medial, lateral and posterior carinae, margins elevated, punctations indistinct; ocelli closely adjacent to eyes, laterad of submarginal carinae, directly above antennal ledges; transition from crown to face sharp, indicated by transverse carina; antennal ledges prominent, with anterior depression; frontoclypeus with complete median longitudinal carina; anteclypeus with apex truncate; maxillary suture absent.

Pronotum ( Figs 8-11, 13-14 ) with pair of carinae or with median anterior depression. Forewings ( Figs 17, 19 ) without R1 and crossveins r-m1 and m-cu2. Hind wings ( Figs 18, 20 ) with crossvein m-cu oblique relative to CuA; submarginal vein extended onto jugum. Forefemora with intercalary row weakly arcuate. Hind tibiae with row PD without macrosetae and row PV without blunt-tipped setae.

Female ovipositor sigmoid, broadened near midlength; first valvulae with dorsal sculpturing strigate; second valvulae with dorsal teeth numerous, close-set, and bidentate; toothed area occupying more than half entire length of valvula.

Male terminalia ( Figs 29 - 42 ) with pygofer with well-developed posteroventral process; valve articulated laterally to pygofer; subgenital plates extended posteriorly beyond pygofer lobe apex; style with preapical teeth or denticuli; dorsal connective absent; anal tube segment X with or without lobes and/or processes at base or more apically; aedeagus divided into ventral paraphyses-like structure articulated to connective consisting of basal preatrium and paired robust processes and dorsal shaft, dorsal and ventral parts may be loosely connected by membrane (all Oriental species) or completely fused to eachother (some African species).
