DIAGNOSIS: Easily recognized by the ovoid body, smooth and rounded head, usually widely hyaline hemelytra with the partly pigmented apices of the corium and cuneus (Fig.
Full white dots (??) represent eggs laid on the exposed dorsal and ventral body sides; full black dots (*) represent eggs laid under the wings in 2 distinct portions of the forewings (hemelytra) that cover the abdomen, i.e., the coriaceous anterior portion (Cp) and the membranous posterior portion (Mp).
Head pronotum, scutellum, is dull ochraceous, thickly and densely punctured with dark brown tinge; eyes dark brown with outer border dull ochraceous; ocelli pale ochraceous; antennae brown; pronotum and scutellum streaked with dark and light stripes; apex of scutellum light brown, with few dark brown puncture; each segment of abdomen dark brown with middle portion light brown; membrane of hemelytra bright brown with dark veins; labium ochraceous except a little basal portion of 3rd and entire 4th segment are brown; legs ochraceous brown with dark patches.
A unique, unreported feature present in certain mainland African and Middle Eastern Laccocorinae is a transverse fracture of the hemelytra extending from near the distal end of the embolium through the apex of the claval commissure (Figs 15, 17, 19).
