Pro- and mesopleuron black; mesepimeron weakly and narrowly tinged with yellow dorsally and ventrally; metepisternum fuscous anteriorly, dark yellow posteriorly, scent gland evaporative areas and peritreme yellow; metepimeron dark brown. Hemelytron. Yellow fuscous with brown and black areas; clavus, endocorium and cuneus fuscous, entirely mottled with yellow and with brown mottling medially; clavus with relatively large, yellow patch subapically; endocorium with blackish patch apically; cuneus with blackish tinge near medial part on inner margin; exocorium and embolium yellow, tinged with fuscous and brown; membrane with indistinct yellow tinges ( Fig. 1A View FIGURE 1 ). Legs. Coxae yellow; fore coxa weakly tinged with red; femora dark brown fuscous with two irregular annulations near apex, apical part weakly tinged with red; profemur weakly and narrowly tinged with yellow; meso- and metafemora with well-developed yellow tinge; tibiae and tarsi dark yellow ( Figs 1A, C View FIGURE 1 ).
