10-13mm. This, the next species, eusema Prout and quadratifera Walker all have rather similarly patterned forewings which have a dark subtornal spot. G. lapidarioides has rather uniform brown forewings somewhat akin to those of lapidaria Walker (Sri Lanka); there are faint, fine, curved fasciae in the medial zone that may bound zones of paler or darker ground colour, and in one specimen are clearly defined in dark brown (illustrated). The male genitalia are as in quadratifera with a harpe that is not bulbous and is relatively slender. The female genitalia are distinctive, having narrow, acute (rather than rounded) ovipositor lobes with unusually long apophyses; there is no signum and the ductus bursae is long with a kink at one third.
