Pronotum with sparse, subappressed setae around lateral margins. Scutellum wider than long. Elytral disc deplanate, with indistinct strial-interstrial pattern (a character defined by Krikken, 2009 ). Elytra glabrous, with symmetric pattern of yellow patches on darker green background, or unmarked uniform dark green. Apicosutural elytral angle rounded off. Pygidium distinctly transverse, sparsely clad with erect, fine setae. Mesometasternal protrusion absent, mesocoxae subcontiguous. Tarsomeres without apico-internal tuft of setae. Protibia with 1 external denticle and 1 apical tooth, without proximal serration. Apico-internal spur of protibia present, movable. Protarsomere 1 about as long as protarsomere 2, not dilated. Mesotibiae and metatibiae straight. Mesotibia with an internal tooth. Mesotibial apex not extended beyond apex as a drawn-out lobe (a character defined by Krikken 2009 ). Mesotibial spurs present.
